手术目标物体3是人造肢体，例如是假上肢、假手(hand phantom)、假手掌、假手指、假手臂、假上臂、假前臂、假手肘、假上肢、假脚、假脚趾、假脚踝、假小腿、假大腿、假膝盖、假躯干、假颈、假头、假肩、假胸、假腹部、假腰、假臀或其他假部位等等。Thesurgical target object 3 is an artificial limb, such as artificial upper limbs, hand phantoms, artificial palms, artificial fingers, artificial arms, artificial upper arms, artificial forearms, artificial elbows, artificial upper limbs, artificial feet, artificial toes, artificial ankles, artificial Calf, false thigh, false knee, false torso, false neck, false head, false shoulder, false chest, false abdomen, false waist, false hip or other false parts, etc.

在本实施例中，训练系统是以手指的微创手术训练为例说明，手术例如是板机指治疗手术，手术目标物体3是假手，医疗探具21是拟真超声波换能器(或探头)，手术器具22～24是针(needle)、扩张器(dilator)及勾刀(hook blade)。在其他的实施方式中，针对其他的手术训练可以采用其他部位的手术目标物体3。In this embodiment, the training system takes the minimally invasive surgery training of the fingers as an example. The surgery is a trigger finger treatment operation, thesurgical target object 3 is a prosthetic hand, and themedical probe 21 is a realistic ultrasonic transducer (or probe). ), the surgical instruments 22-24 are a needle, a dilator, and a hook blade. In other embodiments, other surgical target objects 3 may be used for other surgical training.

储存元件132还储存实体医学影像三维模型14b、人造医学影像三维模型14c及训练模块16的程序码与数据，处理核心131可存取储存元件132以执行及处理实体医学影像三维模型14b、人造医学影像三维模型14c及训练模块16的程序码与数据。训练模块16负责以下手术训练流程的进行以及相关数据的处 理、整合与计算。Thestorage element 132 also stores the program codes and data of the physical medicalimage 3D model 14b, the artificial medicalimage 3D model 14c, and thetraining module 16. Theprocessing core 131 can access thestorage element 132 to execute and process the physical medicalimage 3D model 14b and artificial medicine. The program code and data of theimage 3D model 14c and thetraining module 16. Thetraining module 16 is responsible for the following surgical training procedures and the processing, integration and calculation of related data.

手术训练用的影像模型在手术训练流程进行前预先建立及汇入系统。以手指微创手术训练为例，影像模型的内容包含手指骨头(掌指及近端指骨)及屈肌腱(flexor tendon)。这些影像模型可参考图5A至图5C，图5A为一个实施例的手术情境三维模型的示意图，图5B为一个实施例的实体医学影像三维模型的示意图，图5C为一个实施例的人造医学影像三维模型的示意图。这些三维模型的内容可以通过输出装置5来输出或列印。The image model for surgical training is pre-established and imported into the system before the surgical training process. Taking minimally invasive finger surgery training as an example, the content of the image model includes finger bones (metacarpal and proximal phalanx) and flexor tendons. For these image models, refer to FIGS. 5A to 5C. FIG. 5A is a schematic diagram of a three-dimensional model of an operation scenario according to an embodiment, FIG. 5B is a schematic diagram of a physical medical image three-dimensional model according to an embodiment, and FIG. 5C is an artificial medical image according to an embodiment. Schematic of the three-dimensional model. The content of these three-dimensional models can be output or printed by the output device 5.

实体医学影像三维模型14b是从医学影像建立的三维模型，其是针对手术目标物体3所建立的模型，例如像图5B出示的三维模型。医学影像例如是电脑断层摄影影像，手术目标物体3实际地经电脑断层摄影后产生的影像拿来建立实体医学影像三维模型14b。The solid medical image three-dimensional model 14b is a three-dimensional model established from medical images, which is a model established for thesurgical target object 3, such as the three-dimensional model shown in FIG. 5B. The medical image is, for example, a computer tomography image, and the image of thesurgical target object 3 actually generated after the computer tomography is used to build the three-dimensional model 14b of the physical medical image.

人造医学影像三维模型14c内含人造医学影像模型，人造医学影像模型是针对手术目标物体3所建立的模型，例如像图5C出示的三维模型。举例来说，人造医学影像模型是人造超声波影像三维模型，由于手术目标物体3并非真的生命体，虽然电脑断层摄影能得到实体结构的影像，但是若用其他的医学影像设备如超声波影像则仍无法直接从手术目标物体3得到有效或有意义的影像。因此，手术目标物体3的超声波影像模型必须以人造的方式产生。从人造超声波影像三维模型选择适当的位置或平面可据以产生二维人造超声波影像。The artificial medical image three-dimensional model 14c contains an artificial medical image model. The artificial medical image model is a model established for thesurgical target object 3, such as the three-dimensional model shown in FIG. 5C. For example, the artificial medical imaging model is a three-dimensional model of artificial ultrasound imaging. Since thesurgical target 3 is not a real living body, although computer tomography can obtain images of the physical structure, it is still possible to use other medical imaging equipment such as ultrasound imaging. Effective or meaningful images cannot be obtained directly from thesurgical target object 3. Therefore, the ultrasound image model of thesurgical target object 3 must be artificially generated. Selecting an appropriate position or plane from the three-dimensional model of artificial ultrasound images can generate two-dimensional artificial ultrasound images.

计算机装置13依据手术情境三维模型14a以及医学影像模型产生医学影像136，医学影像模型例如是实体医学影像三维模型14b或人造医学影像三维模型14c。举例来说，计算机装置13依据手术情境三维模型14a以及人造医学影像三维模型14c产生医学影像136，医学影像136是二维人造超声波影像。计算机装置13依据医疗探具呈现物141找出的检测物及手术器具呈现物145的操作进行评分，检测物例如是特定的受术部位。Thecomputer device 13 generates amedical image 136 according to the three-dimensional model 14a of the surgical situation and the medical image model. The medical image model is, for example, a solid medical image three-dimensional model 14b or an artificial medical image three-dimensional model 14c. For example, thecomputer device 13 generates amedical image 136 based on the three-dimensional model 14a of the surgical situation and the three-dimensional model 14c of an artificial medical image. Themedical image 136 is a two-dimensional artificial ultrasound image. Thecomputer device 13 scores the detection object found by themedical probe 141 and the operation of thesurgical instrument representation 145, such as a specific surgical site.

图6A至图6D为一个实施例的医疗用具的方向向量的示意图。对应于医疗用具21～24的医疗用具呈现物141～144的方向向量会即时地描绘(rendering)，以医疗用具呈现物141来说，医疗探具的方向向量可以通过计算光学标记物的重心点而得到，然后从另一点投射到x-z平面，计算从重心点到投射点的向量。其他的医疗用具呈现物142～144较为简单，用模型中的尖点就能计算方向向量。6A to 6D are schematic diagrams of the direction vector of the medical appliance according to an embodiment. The direction vectors of the medical device presentation objects 141-144 corresponding to the medical devices 21-24 will be rendered instantly. For the medicaldevice presentation object 141, the direction vector of the medical probe can be calculated by calculating the center of gravity of the optical marker And get, and then project from another point to the xz plane, and calculate the vector from the center of gravity to the projection point. Other medical appliance presentations 142-144 are relatively simple, and the direction vector can be calculated using the sharp points in the model.

为了降低系统负担避免延迟，影像描绘的量可以减少，例如训练系统可以仅绘制手术目标呈现物145所在区域的模型而非全部的医疗用具呈现物141～144都要绘制。In order to reduce the burden of the system and avoid delays, the amount of image rendering can be reduced. For example, the training system can only draw the model of the area where the surgicaltarget presenting object 145 is located instead of drawing all the medical appliance presenting objects 141-144.

此外，在训练系统中，皮肤模型的透明度可以调整以观察手术目标呈现物145内部的解剖结构，并且看到不同横切面的超声波影像切片或电脑断层摄影影像切片，横切面例如是横断面(horizontal plane或axial plane)、矢面(sagittal plane)或冠状面(coronal plane)，由此可在手术过程中帮助执刀者。各模型的边界盒(bounding boxes)是建构来碰撞检测(collision detection)，手术训练系统可以判断哪些医疗用具已经接触到肌腱、骨头及/或皮肤，以及可以判断何时开始评分。In addition, in the training system, the transparency of the skin model can be adjusted to observe the internal anatomical structure of the surgical target present 145, and to see ultrasound image slices or computer tomography image slices of different cross-sections, such as horizontal cross-sections. plane or axial plane), sagittal plane (sagittal plane) or coronal plane (coronal plane), which can help the operator during the operation. The bounding boxes of each model are constructed to detect collisions. The surgical training system can determine which medical appliances have contacted tendons, bones and/or skin, and can determine when to start scoring.

进行校正程序前，附在手术目标物体3上的光学标记物11必须要能清楚地被光学感测器12看到或检测到，如果光学标记物11被遮住则检测光学标记物11的位置的准确度会降低，光学感测器12至少同时需要两个看到全部的光学标记物。校正程序如前所述，例如三阶段校正，三阶段校正用来准确地校正两个坐标体系。校正误差、迭代计数和光学标记物的最后位置可以显示在训练系统的视窗中，例如通过输出装置5显示。准确度和可靠度资讯可用来提醒使用者，当误差过大时系统需要重新校正。完成坐标体系校正后，三维模型以每秒0.1次的频率来描绘，描绘的结果可输出到输出装置5来显示或列印。Before performing the calibration procedure, theoptical marker 11 attached to thesurgical target object 3 must be clearly seen or detected by theoptical sensor 12. If theoptical marker 11 is covered, the position of theoptical marker 11 is detected The accuracy of is reduced, and theoptical sensor 12 needs at least two to see all the optical markers at the same time. The calibration procedure is as described above, for example, three-stage calibration, which is used to accurately calibrate two coordinate systems. The correction error, the iteration count, and the final position of the optical marker can be displayed in the window of the training system, for example, by the output device 5. The accuracy and reliability information can be used to remind users that the system needs to be recalibrated when the error is too large. After the coordinate system is corrected, the three-dimensional model is drawn at a frequency of 0.1 times per second, and the drawn result can be output to the output device 5 for display or printing.

训练系统准备好后，使用者可以开始进行手术训练流程。在训练流程中，首先使用医疗探具寻找受术部位，找到受术部位后，将受术部位麻醉。然后，扩张从外部通往受术部位的路径，扩张后，将手术刀沿此路径深入至受术部位。After the training system is ready, the user can start the surgical training process. In the training process, first use a medical probe to find the site to be operated on. After finding the site to be operated on, the site is anesthetized. Then, expand the path from the outside to the surgical site, and after expansion, the scalpel is deepened along this path to the surgical site.

图7A至图7D为一个实施例的训练系统的训练过程示意图，手术训练流程包含四阶段并以手指的微创手术训练为例说明。7A to 7D are schematic diagrams of the training process of the training system of an embodiment. The surgical training process includes four stages and is illustrated by taking minimally invasive surgery training of fingers as an example.

如图7A所示，在第一阶段，使用医疗探具21寻找受术部位，藉以确认受术部位在训练系统内。受术部位例如是滑车区(pulley)，这可通过寻找掌指关节的位置、手指的骨头及肌腱的解剖结构来判断，这阶段的重点在于第一个滑车区(A1 pulley)是否有找到。此外，若受训者没有移动医疗探具超过三秒来决定位置，然后训练系统将自动地进入到下一阶段的评分。在手术训练期间，医疗探具21摆设在皮肤上并且保持与皮肤接触在沿屈肌腱(flexor tendon)的中线(midline)上的掌指关节(metacarpal joints，MCP joints)。As shown in FIG. 7A, in the first stage, themedical probe 21 is used to find the site to be operated on, so as to confirm that the site to be operated on is in the training system. The surgical site is, for example, the pulley area (pulley), which can be judged by looking for the position of the metacarpophalangeal joints, the anatomical structures of the bones and tendons of the fingers, and the focus at this stage is whether the first pulley area (A1 pulley) is found. In addition, if the trainee does not move the medical probe for more than three seconds to determine the position, then the training system will automatically enter the next stage of scoring. During surgical training, themedical probe 21 is placed on the skin and kept in contact with the skin at the metacarpal joints (MCP joints) along the midline of the flexor tendon.

如图7B所示，在第二阶段，使用手术器具22打开手术区域的路径，手术器具22例如是针。插入针来注入局部麻醉剂并且扩张空间，插入针的过程可在连续超声波影像的导引下进行。这个连续超声波影像是人造超声波影像，其是如前述的医学影像136。由于用假手很难模拟区域麻醉，因此，麻醉并没有特别模拟。As shown in FIG. 7B, in the second stage, thesurgical instrument 22 is used to open the path of the surgical area. Thesurgical instrument 22 is, for example, a needle. The needle is inserted to inject local anesthetic and expand the space. The process of inserting the needle can be performed under the guidance of continuous ultrasound images. This continuous ultrasound image is an artificial ultrasound image, which is the aforementionedmedical image 136. Because it is difficult to simulate regional anesthesia with prosthetic hands, anesthesia is not specifically simulated.

如图7C所示，在第三阶段，沿与第二阶段中手术器具22相同的路径推入手术器具23，以创造下一阶段勾刀所需的轨迹。手术器具23例如是扩张器(dilator)。此外，若受训者没有移动手术器具23超过三秒来决定位置，然后训练系统将自动地进入到下一阶段的评分。As shown in FIG. 7C, in the third stage, thesurgical instrument 23 is pushed in along the same path as thesurgical instrument 22 in the second stage to create the trajectory required for hooking the knife in the next stage. Thesurgical instrument 23 is, for example, a dilator. In addition, if the trainee does not move thesurgical instrument 23 for more than three seconds to determine the position, then the training system will automatically enter the next stage of scoring.

如图7D所示，在第四阶段，沿第三阶段创造出的轨迹将手术器具24插入，并且利用手术器具24将滑车区分开(divide)，手术器具24例如是勾刀(hook blade)。第三阶段与第四阶段的重点类似，在手术训练过程中，沿屈肌腱(flexor tendon)两侧附近的血管(vessels)和神经可能会容易地被误切，因此，第三阶段与第四阶段的重点在不仅在没有接触肌腱、神经及血管，还有要开启一个轨迹其大于第一个滑车区至少2mm，藉以留给勾刀切割滑车区的空间。As shown in FIG. 7D, in the fourth stage, thesurgical instrument 24 is inserted along the trajectory created in the third stage, and the pulley is divided by thesurgical instrument 24. Thesurgical instrument 24 is, for example, a hook blade. The focus of the third stage is similar to that of the fourth stage. During the surgical training process, the vessels and nerves near both sides of the flexor tendon may be easily miscut. Therefore, the third stage and the fourth stage The focus of the stage is not only not touching the tendons, nerves and blood vessels, but also opening a track that is at least 2mm larger than the first pulley area, so as to leave space for the hook knife to cut the pulley area.

为了要对使用者的操作进行评分，必须要将各训练阶段的操作量化。首先，手术进行中的手术区域是由如图8A的手指解剖结构所定义，其可分为上边界及下边界。因肌腱上的组织大部分是脂肪不会造成疼痛感，所以手术区域的上边界可以用手掌的皮肤来定义，另外，下边界则是由肌腱所定义。近端深度边界(proximal depth boundary)在10mm(平均第一个滑车区长度)离掌骨头颈(metacarpal head-neck)关节。远端深度边界(distal depth boundary)则不重要，这是因为其与肌腱、血管及神经受损无关。左右边界是由肌腱的宽度(width)所定义，神经及血管位在肌腱的两侧。In order to score the user's operations, the operations of each training phase must be quantified. First of all, the operation area during the operation is defined by the finger anatomy as shown in Figure 8A, which can be divided into an upper boundary and a lower boundary. Because most of the tissue on the tendon is fat and does not cause pain, the upper boundary of the surgical area can be defined by the skin of the palm, and the lower boundary is defined by the tendon. The proximal depth boundary is 10mm (average length of the first trochlear zone) from the metacarpal head-neck joint. The distal depth boundary is not important, because it has nothing to do with tendons, blood vessels, and nerves. The left and right boundaries are defined by the width of the tendon, and nerves and blood vessels are located on both sides of the tendon.

手术区域定义好之后，针对各训练阶段的评分方式如下。在如图7A的第一阶段中，训练的重点在于找到目标物，例如是要被切除的目标物，以手指为例是第一个滑车区(A1pulley)。现实手术过程中，为了要有好的超声波影像品质，医疗探具和骨头主轴的角度最好要接近垂直，可容许的角度偏差为±30°。因此，第一阶段评分的算式如下：After the surgical area is defined, the scoring method for each training stage is as follows. In the first stage of FIG. 7A, the focus of the training is to find the target, such as the target to be excised. Taking the finger as an example is the first pulley area (A1pulley). In actual surgery, in order to have good ultrasound image quality, the angle between the medical probe and the bone spindle should be close to vertical, and the allowable angle deviation is ±30°. Therefore, the scoring formula for the first stage is as follows:

第一阶段分数＝找标的物评分×其权重+探具角度评分×其权重The first stage score = the score of the target object × its weight + the angle score of the probe × its weight

在如图7B的第二阶段中，训练的重点在于使用针来打开手术区域的路径。由于滑车区环绕肌腱，骨头主轴和针之间的距离应该要小比较好。因此，第二阶段评分的算式如下：In the second stage as shown in Figure 7B, the focus of training is to use the needle to open the path of the surgical area. Since the pulley area surrounds the tendon, the distance between the main axis of the bone and the needle should be small. Therefore, the calculation formula for the second stage scoring is as follows:

第二阶段分数＝开口评分×其权重+针角度评分×其权重+离骨头主轴距离评分×其权重Second stage score = opening score × its weight + needle angle score × its weight + distance from the main axis of the bone score × its weight

在第三阶段中，训练的重点在于将扩大手术区域的扩张器插入手指。在手术过程中，扩张器的轨迹必须要接近骨头主轴。为了不伤害肌腱、血管与神经，扩张器不会超出先前定义的手术区域边界。为了扩张出好的手术区域轨迹，扩 张器与骨头主轴的角度最好近似于平行，可容许的角度偏差为±30°。由于要留给勾刀切割第一个滑车区的空间，扩张器必须要高于(over)第一个滑车区至少2mm。第三阶段评分的算式如下：In the third stage, the focus of training is to insert a dilator that enlarges the surgical area into the finger. During the operation, the trajectory of the dilator must be close to the main axis of the bone. In order not to damage tendons, blood vessels and nerves, the dilator will not exceed the previously defined boundary of the surgical area. In order to expand a good trajectory of the surgical area, the angle between the expander and the main axis of the bone should be approximately parallel, and the allowable angle deviation is ±30°. Due to the space left for the hook knife to cut the first trolley area, the expander must be at least 2mm higher than the first trolley area. The third stage scoring formula is as follows:

第三阶段分数＝高于滑车区评分×其权重+扩张器角度评分×其权重+离骨头主轴距离评分×其权重+未离开手术区域评分×其权重The third stage score = higher than the pulley area score × its weight + expander angle score × its weight + distance from the main axis of the bone score × its weight + not leaving the surgical area score × its weight

在第四阶段中，评分的条件和第三阶段类似，不同处在于勾刀需要旋转90°，这规则加入到此阶段的评分中。评分的算式如下：In the fourth stage, the scoring conditions are similar to those in the third stage, except that the hook needs to be rotated 90°. This rule is added to the scoring at this stage. The scoring formula is as follows:

第四阶段分数＝高于滑车区评分×其权重+勾刀角度评分×其权重+离骨头主轴距离评分×其权重+未离开手术区域评分×其权重+旋转勾刀评分×其权重The fourth stage score = higher than the pulley area score × its weight + hook angle score × its weight + distance from the main axis of the bone score × its weight + not leaving the surgical area score × its weight + rotating hook score × its weight

为了要建立评分标准以对使用者的手术操作做评分，必须定义如何计算骨头主轴和医疗用具间的角度。举例来说，这个计算方式是和计算手掌法线(palm normal)和医疗用具的方向向量间的角度一样。首先，要先找到骨头主轴，如图8B所示，从电脑断层摄影影像在骨头上采用主成分分析(Principal components analysis，PCA)可找出骨头的三个轴。在这三个轴中，取最长的轴作为骨头主轴。然而，在电脑断层摄影影像中骨头形状并非平的(uneven)，这造成主成分分析找到的轴和手掌法线彼此不垂直。于是，如图8C所示，代替在骨头上采用主成分分析，在骨头上的皮肤可用来采用主成分分析找出手掌法线。然后，骨头主轴和医疗用具之间的角度可据以计算得到。In order to establish a scoring standard to score the user's surgical operation, it is necessary to define how to calculate the angle between the bone spindle and the medical appliance. For example, this calculation method is the same as calculating the angle between the palm normal and the direction vector of the medical appliance. First, find the main axis of the bone. As shown in Figure 8B, the three axes of the bone can be found by using principal component analysis (PCA) on the bone from the computed tomography image. Among the three axes, the longest axis is taken as the main axis of the bone. However, the shape of the bone in the computer tomography image is not uniform, which causes the axis found by the principal component analysis and the palm normal line to be not perpendicular to each other. Thus, as shown in FIG. 8C, instead of using principal component analysis on the bone, the skin on the bone can be used to find the palm normal using principal component analysis. Then, the angle between the bone spindle and the medical appliance can be calculated.

计算骨头主轴与用具的角度后，骨头主轴与算医疗用具间的距离也需要计算，距离计算类似于计算医疗用具的顶尖和平面间的距离，平面指包含骨头主轴向量向量和手掌法线的平面，距离计算的示意如图8D所示。这个平面可利用手掌法线的向量D2和骨头主轴的向量D1的外积(cross product)得到。由于这两个向量可在先前的计算得到，骨头主轴与用具之间的距离可容易地算出。After calculating the angle between the bone main axis and the appliance, the distance between the bone main axis and the medical appliance also needs to be calculated. The distance calculation is similar to calculating the distance between the top and the plane of the medical appliance. The plane refers to the plane containing the bone main axis vector vector and the palm normal. , The schematic diagram of distance calculation is shown in Figure 8D. This plane can be obtained by the cross product of the palm normal vector D2 and the bone principal axis vector D1. Since these two vectors can be obtained in the previous calculation, the distance between the main axis of the bone and the appliance can be easily calculated.

如图8E所示，图8E为一个实施例的人造医学影像的示意图，人造医学影像中的肌腱区段和皮肤区段以虚线标示。肌腱区段和皮肤区段可用来建构模型及边界盒，边界盒是用来碰撞检测，滑车区可以定义在静态模型。通过使用碰撞检测，可以决定手术区域及判断医疗用具是否跨过滑车区。第一个滑车区的平均长度约为1mm，第一个滑车区是位在掌骨头颈(MCP head-neck)关节近端，滑车区平均厚度约0.3mm并且环绕肌腱。As shown in FIG. 8E, FIG. 8E is a schematic diagram of an artificial medical image according to an embodiment, and the tendon section and the skin section in the artificial medical image are marked with dotted lines. The tendon section and the skin section can be used to construct the model and the bounding box, the bounding box is used for collision detection, and the pulley area can be defined in the static model. By using collision detection, it is possible to determine the surgical area and determine whether the medical appliance crosses the pulley area. The average length of the first pulley area is about 1mm, and the first pulley area is located at the proximal end of the metacarpal head-neck (MCP) joint. The average thickness of the pulley area is about 0.3mm and surrounds the tendons.

图9A为一个实施例的产生人造医学影像的流程图。如图9A所示，产生的流程包括步骤S21至步骤S24。Fig. 9A is a flow chart of generating artificial medical images according to an embodiment. As shown in FIG. 9A, the generated flow includes step S21 to step S24.

步骤S21是从人造肢体的断面影像数据取出第一组骨皮特征。人造肢体是前述手术目标物体3，其可作为微创手术训练用肢体，例如是假手。断面影像数据包含多个断面影像，断面参考影像为电脑断层摄影(computed tomography)影像或实体剖面影像。Step S21 is to extract the first set of bone skin features from the cross-sectional image data of the artificial limb. The artificial limb is the aforementionedsurgical target object 3, which can be used as a limb for minimally invasive surgery training, such as a prosthetic hand. The cross-sectional image data includes multiple cross-sectional images, and the cross-sectional reference image is a computed tomography image or a solid cross-sectional image.

步骤S22是从医学影像数据取出第二组骨皮特征。医学影像数据为立体超声波影像，例如像图9B的立体超声波影像，立体超声波影像由多个平面超声波影像所建立。医学影像数据是对真实生物拍摄的医学影像，并非是对人造肢体肢体拍摄。第一组骨皮特征及第二组骨皮特征包含多个骨头特征点以及多个皮肤特征点。Step S22 is to extract the second set of bone skin features from the medical image data. The medical image data is a three-dimensional ultrasound image, such as the three-dimensional ultrasound image of FIG. 9B, which is created by multiple planar ultrasound images. Medical image data are medical images taken of real organisms, not artificial limbs. The first group of bone skin features and the second group of bone skin features include multiple bone feature points and multiple skin feature points.

步骤S23是根据第一组骨皮特征及第二组骨皮特征建立特征对位数据(registration)。步骤S23包含：以第一组骨皮特征为参考目标(target)；找出关联函数作为空间对位关联数据，其中关联函数满足第二组骨皮特征对准参考目标时没有因第一组骨皮特征与第二组骨皮特征造成的扰动。关联函数是通过最大似然估计问题(maximum likelihood estimation problem)的演算法以及最大期望演算法(EM Algorithm)找出。Step S23 is to establish feature registration data (registration) based on the first set of bone and skin features and the second set of bone and skin features. Step S23 includes: taking the first set of bone-skin features as a reference target (target); finding out the correlation function as the spatial alignment correlation data, where the correlation function satisfies the second set of bone-skin features to align with the reference target without being due to the first set of bones Disturbance caused by skin features and the second set of bone skin features. The correlation function is found through the algorithm of the maximum likelihood estimation problem (maximum likelihood estimation problem) and the maximum expectation algorithm (EM Algorithm).

步骤S24是根据特征对位数据对于医学影像数据进行形变处理，以产生适用于人造肢体的人造医学影像数据。人造医学影像数据例如是立体超声波影像，其仍保留原始超声波影像内生物体的特征。步骤S24包含：根据医学影像数据以及特征对位数据产生形变函数；在医学影像数据套用网格并据以得到多个网点位置；依据形变函数对网点位置进行形变；基于形变后的网点位置，从医学影像数据补入对应像素以产生形变影像，形变影像作为人造医学影像数据。形变函数是利用移动最小二乘法(moving least square，MLS)产生。形变影像是利用仿射变换(affine transform)产生。Step S24 is to perform deformation processing on the medical image data according to the feature alignment data to generate artificial medical image data suitable for artificial limbs. The artificial medical image data is, for example, a three-dimensional ultrasound image, which still retains the characteristics of the organism in the original ultrasound image. Step S24 includes: generating a deformation function based on the medical image data and feature alignment data; applying a grid to the medical image data and obtaining multiple dot positions accordingly; deforming the dot positions according to the deformation function; based on the deformed dot positions, The medical image data is supplemented with corresponding pixels to generate a deformed image, and the deformed image is used as artificial medical image data. The deformation function is generated using the moving least square (MLS) method. The deformed image is generated using affine transform.

通过步骤S21至步骤S24，通过将真人超声波影像与假手电脑断层影像撷取影像特征，利用影像对位取得形变的对应点关系，再通过形变的方式基于假手产生接近真人超声波的影像，并使产生的超声波保有原先真人超声波影像中的特征。以人造医学影像数据是立体超声波影像来说，某特定位置或特定切面的平面超声波影像可根据立体超声波影像对应的位置或切面产生。Through step S21 to step S24, by capturing the image characteristics of the real ultrasonic image and the artificial hand computer tomography image, the corresponding point relationship of the deformation is obtained by image registration, and then the ultrasonic image close to the real human is generated based on the artificial hand through the deformation The ultrasound retains the characteristics of the original live ultrasound image. If the artificial medical image data is a three-dimensional ultrasound image, a plane ultrasound image of a specific position or a specific section can be generated based on the corresponding position or section of the three-dimensional ultrasound image.

如图10A与图10B所示，图10A与图10B为一个实施例的假手模型与超声波容积(ultrasound volume)的校正的示意图。实体医学影像三维模型14b及人造医学影像三维模型14c彼此之间有关联，由于假手的模型是由电脑断层影像容积所建构，因此可以直接拿电脑断层影像容积与超声波容积间的位置关系来 将假手和超声波容积建立关联。As shown in FIG. 10A and FIG. 10B, FIG. 10A and FIG. 10B are schematic diagrams of the correction of the artificial hand model and the ultrasonic volume according to an embodiment. The physical medicalimage 3D model 14b and the artificial medicalimage 3D model 14c are related to each other. Since the model of the prosthetic hand is constructed by the computed tomographic image volume, the positional relationship between the computed tomographic image volume and the ultrasound volume can be directly used to integrate the artificial hand. Establish correlation with ultrasound volume.

如图10C与图10D所示，图10C为一个实施例的超声波容积以及碰撞检测的示意图，图10D为一个实施例的人造超声波影像的示意图。训练系统要能模拟真实的超声波换能器(或探头)，从超声波容积产生切面影像片段。不论换能器(或探头)在任何角度，模拟的换能器(或探头)必须描绘对应的影像区段。在实际操作中，首先检测医疗探具21与超声波体之间的角度，然后，片段面的碰撞检测是依据医疗探具21的宽度及超声波容积，其可用来找到正在描绘的影像区段的对应值，产生的影像如图10D所示。例如人造医学影像数据是立体超声波影像来说，立体超声波影像有对应的超声波容积，模拟的换能器(或探头)要描绘的影像区段的内容可根据立体超声波影像对应的位置产生。As shown in FIG. 10C and FIG. 10D, FIG. 10C is a schematic diagram of ultrasonic volume and collision detection according to an embodiment, and FIG. 10D is a schematic diagram of an artificial ultrasound image according to an embodiment. The training system must be able to simulate a real ultrasonic transducer (or probe) to generate slice image fragments from the ultrasonic volume. Regardless of the angle of the transducer (or probe), the simulated transducer (or probe) must depict the corresponding image segment. In actual operation, the angle between themedical probe 21 and the ultrasonic body is first detected. Then, the collision detection of the segment surface is based on the width of themedical probe 21 and the ultrasonic volume, which can be used to find the corresponding image segment being drawn. Value, the resulting image is shown in Figure 10D. For example, if the artificial medical image data is a three-dimensional ultrasound image, the three-dimensional ultrasound image has a corresponding ultrasound volume, and the content of the image segment to be depicted by the simulated transducer (or probe) can be generated according to the corresponding position of the three-dimensional ultrasound image.

如图11A与图11B所示，图11A与图11B为一个实施例的操作训练系统的示意图。手术受训者操作医疗用具，在显示装置上可即时对应地显示医疗用具。如图12A与图12B所示，图12A与图12B为一个实施例的训练系统的影像示意图。手术受训者操作医疗用具，在显示装置上除了可即时对应地显示医疗用具，也可即时地显示当下的人造超声波影像。As shown in FIG. 11A and FIG. 11B, FIG. 11A and FIG. 11B are schematic diagrams of an operation training system according to an embodiment. Surgery trainees operate medical appliances, and the medical appliances can be correspondingly displayed on the display device in real time. As shown in FIGS. 12A and 12B, FIGS. 12A and 12B are schematic diagrams of images of the training system according to an embodiment. Operation trainees operate medical appliances. In addition to correspondingly displaying the medical appliances on the display device, the current artificial ultrasound images can also be displayed in real time.
