Wherein, the processor 1 is the core component of the present invention, and its interior includes animage collector 5, animage processor 6 and animage manager 7, and theimage collector 5 is used to collect image information, and transmit the collected image information to theimage Processor 6; theimage processor 6 processes and processes the image information collected by theimage collector 5 to obtain the image required by the user; the processed and processed image is directly displayed on thedisplay screen 2 and transmitted to the image manager at thesame time 7. Store it in case the user calls it at any time.Display screen 2,keyboard 3 and mouse 4 are all connected with processor 1, anddisplay screen 2, as the output device of processor 1, can visually display images to facilitate users to browse, judge and analyze;keyboard 3 and mouse 4 are used as processing The input device of the device can manipulate the processor 1, so that the user can process and process the image according to his own needs and judgment.

影像处理器6包括影像二维处理装置8、影像三维处理装置9、影像测量装置10、影像配准装置11、影像分割装置12。Theimage processor 6 includes an image two-dimensional processing device 8 , an image three-dimensional processing device 9 , animage measurement device 10 , animage registration device 11 , and animage segmentation device 12 .

参见图3,显示屏2由三个二维视图窗口和一个三维视图窗口组成,三个二维视图窗口分别为横断位窗口、矢状位窗口、冠状位窗口。Referring to FIG. 3 , thedisplay screen 2 is composed of three two-dimensional view windows and one three-dimensional view window. The three two-dimensional view windows are respectively a transverse view window, a sagittal view window and a coronal view window.

影像二维处理装置8由影像基本处理装置及影像裁剪装置两部分构成。影像基本处理装置包括针对单幅影像的滤波处理及针对两幅影像的算术运算处理。单幅影像的滤波处理包括:噪声抑制、形态运算、边缘检测以及其它处理方式。两幅影像的算术运算包括算术运算和布尔运算。影像裁剪装置一般会分析所有影像数据,为获得更好的对比度及更加灵活的操作方式,用户可执行裁剪操作来选择部分区域数据执行影像处理操作。The two-dimensionalimage processing device 8 is composed of two parts: a basic image processing device and an image cropping device. The basic image processing device includes filtering processing for a single image and arithmetic operation processing for two images. The filtering processing of a single image includes: noise suppression, morphological operations, edge detection and other processing methods. Arithmetic operations on two images include arithmetic operations and Boolean operations. The image cropping device generally analyzes all the image data. In order to obtain better contrast and more flexible operation mode, the user can perform a cropping operation to select part of the area data to perform image processing operations.

影像三维处理装置由“体绘制”及“视频制作”两部分组成。体数据当中的每一个点都可以分配一个光线的发射与吸收参数。这样,通过模拟光线在体内部的传播,就能够实现体数据在任意视角条件下的显示。影像处理结果可以通过制作视频录制将视频或视图截屏保存下来。The image three-dimensional processing device consists of two parts: "volume rendering" and "video production". Each point in the volume data can be assigned a ray emission and absorption parameter. In this way, by simulating the propagation of light inside the volume, the display of volume data under any viewing angle can be realized. The image processing result can be saved by making a video recording to save the video or view screenshot.

It can measure distances, angles, paths, and some geometric figures. After performing a measurement operation, the same or different measurement graphics associated with the selected image can be saved for future use. When multiple graphics are drawn on the image, the current application graphics will be displayed in red, and other application graphics will be displayed in white, and the displayed value on the image is the return value of the current application graphics. All measurement graphics will each generate a node of the image tree to be displayed in the data manager. Individual survey graphics or images that are no longer needed can be deleted individually or as a group in the data manager.

影像配准装置由“点配准”、“刚体配准”及“非刚体配准”三部分组成。医学影像配准是指将一组医学影像经空间变换后,使它与另一组保持不动的医学影像上的对应点达到空间上的一致。保持不动的叫做参考影像,做变换的称作浮动影像。配准的结果应用于浮动影像。The image registration device consists of three parts: "point registration", "rigid body registration" and "non-rigid body registration". Medical image registration refers to spatially transforming a set of medical images to achieve spatial consistency with corresponding points on another set of medical images that remain still. The one that remains still is called the reference image, and the one that is transformed is called the floating image. The result of the registration is applied to the floating image.

影像分割装置能够在人体的医学影像上为解剖结构及病理结构创建分割。包括交互式分割及血管分割两部分。以下以肝脏为例,说明影像分割装置的工作原理。The image segmentation device is capable of creating segmentations for anatomical and pathological structures on medical images of the human body. It includes two parts: interactive segmentation and vessel segmentation. The following takes the liver as an example to illustrate the working principle of the image segmentation device.

血管分割包括基于阈值的血管分割和基于模型的血管重建两步。Vessel segmentation includes two steps: threshold-based vessel segmentation and model-based vessel reconstruction.

影像基本要求为血管强化过CT数据,层厚≤2mm,且血管CT体素平均值大于周围器官30个灰度值,基本能看到血管就可用于分割(核磁也可以,不过对操作人员要求较高不建议采用核磁影像)。The basic requirements for imaging are blood vessels enhanced CT data, slice thickness ≤ 2mm, and the average value of vascular CT voxels greater than 30 gray values of surrounding organs, and blood vessels can be basically seen for segmentation (nuclear magnetic resonance is also possible, but there are requirements for operators) Higher MRI is not recommended).

基于阈值的血管分割操作步骤如下:The operation steps of threshold-based blood vessel segmentation are as follows:

(1)选取种子点(1) Select the seed point

(2)确定阈值(2) Determine the threshold

即确定血管的上下阈值,把鼠标移动到血管内,确定阈值范围,点击预览观查分割效果,调整阈值,直到取得较理想的血管分割数据。That is to determine the upper and lower thresholds of the blood vessel, move the mouse into the blood vessel, determine the threshold range, click the preview to view the segmentation effect, and adjust the threshold until the ideal blood vessel segmentation data is obtained.

(3)血管分割(3) Blood vessel segmentation

确定完阈值后点击分割按钮,等待分割完成的血管数据。After determining the threshold, click the segmentation button and wait for the segmented blood vessel data.

(4)基于模型的血管重建(4) Model-based vessel reconstruction

完成分割后的血管比较粗糙,无法完成后续的各种分析,因此需要对血管进行重建,首先在三维窗口选取血管的起点(一般为一个点),然后按照你所需要的血管分支选取血管的终止点,未选取的分支则不重建,选择好种子点之后点击重建按钮,此步骤耗时较长,等待计算完成就可以看到重建后的血管结果。The blood vessels after segmentation are relatively rough, and subsequent analysis cannot be completed. Therefore, it is necessary to reconstruct the blood vessels. First, select the starting point of the blood vessel (usually a point) in the 3D window, and then select the end of the blood vessel according to the branch of the blood vessel you need. Click, the unselected branches will not be reconstructed. After selecting the seed point, click the rebuild button. This step takes a long time. Wait for the calculation to complete before you can see the reconstructed blood vessel results.

(5)中心线提取(5) Centerline extraction

用于形态分析及血管重建。For morphological analysis and vascular reconstruction.

(6)肝段分割(6) Liver segmentation

能够将肝脏按照医学要求,将肝脏分为八段用不同的颜色显示出来,并将每个肝段内部相应的血管也用不同的颜色显示出来。According to medical requirements, the liver can be divided into eight segments and displayed in different colors, and the corresponding blood vessels inside each liver segment can also be displayed in different colors.

Referring to Fig. 12, through the reconstructed 3D rendering, it can be clearly seen whether there is a risk in the pre-delineated ablation safety boundary, and the safety boundary can be re-delineated according to the actual situation.

(3)将肝脏三维重建模型生成三维PDF报告。参见图13,规划完成后,可实现将肝脏三维重建模型及各项信息导出到PDF软件,并生成三维PDF报告。(3) Generate a 3D PDF report from the liver 3D reconstruction model. See Figure 13.
