放射线人体检查方法和放射线人体检查系统Radiation body examination method and radiation body examination system

技术领域technical field

本发明的实施例涉及放射线人体检查方法和放射线人体检查系统，例如用于机场、车站、海关等涉及安全检查的领域和/或医院等涉及人体医学辐射诊疗的领域。Embodiments of the present invention relate to a radiation body examination method and a radiation body examination system, for example, for airports, stations, customs and other fields involving security inspection and/or hospitals and other fields involving human medical radiation diagnosis and treatment.

背景技术Background technique

放射线人体安全检查广泛地用于机场、海关、车站等场所。常用的放射线检查技术包括放射线透视成像及放射线背散射成像。放射线透射成像技术是指利用放射线穿过被检查人体，由计算机分析处理穿过人体之后的放射线信号，形成人体透视图像，这是目前检查人体体内藏匿物品的主要技术手段。放射线背散射技术则是使用微量放射线扫描被检人，通过接收人体表面散射回的射线信号，获取人体表面轮廓图像，这一技术能够有效的检测人体随身携带的危险品。Radiation human safety inspection is widely used in airports, customs, stations and other places. Commonly used radiographic techniques include fluoroscopic imaging and radiation backscatter imaging. Radiation transmission imaging technology refers to the use of radiation passing through the human body to be inspected, and the radiation signal after passing through the human body is analyzed and processed by a computer to form a fluoroscopic image of the human body. Radiation backscattering technology uses trace radiation to scan the subject, and obtains the contour image of the human body surface by receiving the ray signal scattered back from the surface of the human body. This technology can effectively detect the dangerous goods carried by the human body.

人体受照剂量限值是单个人体可接收的受照剂量的上限值，或者单个人体不可接收的受照剂量的下限值。不同放射防护体系，都制定了相应的剂量限值。剂量限值通常包括单次扫描受照剂量限值和年度累积受照剂量限值。放射线人体检查设备需要满足放射防护体系对于剂量限值的要求，以保障被检查者的人体安全。The human exposure dose limit is the upper limit of the exposure dose acceptable to a single human body, or the lower limit value of the unacceptable exposure dose to a single human body. Different radiation protection systems have formulated corresponding dose limits. Dose limits usually include a single scan exposure dose limit and an annual cumulative exposure dose limit. The radiation human body inspection equipment needs to meet the requirements of the radiation protection system for the dose limit to ensure the human safety of the inspected.

但是，目前在使用的放射线类人体检查设备，设计时一般都只考虑了人体单次放射线受照剂量满足放射线防护要求；而对于被检人一定时期内的累积放射线受照剂量，则没有办法提供直接的衡量和控制。而随着现代社会人们被迫接受放射线检查的情况越来越多，累积放射线受照剂量对于人体健康的影响不容忽视。However, the radiation-type human body inspection equipment currently in use is generally only designed to meet the radiation protection requirements for a single dose of radiation exposure to the human body.

Then, the data processor integrated into the radiationbody examination apparatus 12 can add the current rated single radiation scan dose of the radiationbody examination apparatus 12 and the annual cumulative radiation exposure dose of the examinee to obtain an accumulated value; and according to the accumulation Whether the value exceeds the dose limit set by the clouddose information server 20 is determined to determine whether or not to perform the current radiation examination on the subject.

此外，所述个人身份识别设备11可以是独立于放射线人体检查设备的设备，例如可以单独放置于操作台、或由操作人员手持；或者，所述个人身份识别设备11也可以集成到每台放射线人体检查设备12中，例如固定在放射线人体检查设备12的表面上。In addition, thepersonal identification device 11 may be a device independent of the radiation body inspection equipment, for example, it may be placed on the operating table alone, or held by the operator; alternatively, thepersonal identification device 11 may also be integrated into each radiograph In the humanbody inspection apparatus 12, it is fixed to the surface of the radiation humanbody inspection apparatus 12, for example.

当所述放射线人体检查系统包括单台放射线人体检查设备12时，云端剂量信息服务器20可以放置于服务器机房，也可以集成于单台放射线人体检查设备12中。并且，所述个人身份识别设备11和所述数据处理器30也可以集成到单台放射线人体检查设备12中。When the radiation body examination system includes a single radiationbody examination device 12 , the clouddose information server 20 may be placed in a server room, or may be integrated into a single radiationbody examination device 12 . Furthermore, thepersonal identification device 11 and thedata processor 30 may also be integrated into a single radiologicalbody examination device 12 .

如果有多台放射线人体检查设备12时，云端剂量信息服务器20可以放置于机房，也可以集成于联网的某一台放射线人体检查设备12中。If there are multiple radiation human body inspection apparatuses 12 , the clouddose information server 20 may be placed in the computer room, or may be integrated into a certain networked radiation humanbody inspection device 12 .

如图2所示，每台放射线人体检查设备12具体可以包括：放射线机或放射源120，所述放射线机或放射源用于发射放射线，探测器组121，所述探测器组构造成接收放射线并产生电信号，探测器组121可以由排成阵列的多个探测器构成；图像生成装置122，构造成将探测器组的电信号转换成放射线扫描图像；以及剂量确定装置123，构造成提取所述放射线扫描图像中除人体影像以外的残余像素区域的各像素的亮度值，并计算所述残余像素区域的各像素的亮度值的平均值作为单像素平均亮度值，根据所述单像素平均亮度值确定被检查者的本次放射线受照剂量。As shown in FIG. 2 , each radiographic humanbody inspection apparatus 12 may specifically include: a radiation machine or aradiation source 120 for emitting radiation, and adetector group 121 configured to receive radiation And to generate electrical signals, thedetector group 121 may be composed of a plurality of detectors arranged in an array; animage generation device 122 configured to convert the electrical signals of the detector group into a radiographic scan image; and adose determination device 123 configured to extract The luminance value of each pixel in the residual pixel region other than the human body image in the radiographic scan image is calculated, and the average value of the luminance values of each pixel in the residual pixel region is calculated as a single-pixel average luminance value. The brightness value determines the current radiation dose of the examinee.

本领域技术人员可以理解，放射线人体检查设备12还可以包括机械传动装置、电控装置、存储装置、软件程序等，每台放射线人体检查设备12可以具有不同的输出参数、扫描速度、单次扫描人体受照剂量、探测器信号与剂量转换系数等，这里不再赘述。Those skilled in the art can understand that the radiationbody examination equipment 12 may also include mechanical transmission devices, electronic control devices, storage devices, software programs, etc., and each radiationbody examination equipment 12 may have different output parameters, scanning speeds, and single scans. Human exposure dose, detector signal and dose conversion coefficient, etc., will not be repeated here.

对于每台放射线人体检查设备，其探测器信号强度反应接受的放射线剂量大小，探测器信号强度在放射线扫描图像中反映为像素亮度，因此，对设定完成的放射线人体检查设备，其像素亮度与放射线剂量直接相关，像素亮度高，则表明放射线剂量大。对于同一台放射线设备，在特定参数设置下其扫描剂量应当是稳定的，但受环境、设备状态等因素的影响，实际进行放射线检查时放射线扫描剂量会发生波动，而不同于额定放射线扫描剂量。但是，每台设备经出厂校正后其无遮挡物时的平均单像素亮度和扫描剂量的转换系数是固定的，并且存储在设备中。因此，根据无遮挡物时的扫描图像中的平均单像素亮度值，经过转换系数的转换，可以得到实际的扫描剂量值，反映实际的当次个人放射线受照剂量。For each radiation human body inspection equipment, the detector signal intensity reflects the received radiation dose, and the detector signal intensity is reflected in the radiation scan image as the pixel brightness. The radiation dose is directly related, and the pixel brightness is high, indicating that the radiation dose is large. For the same radiation equipment, its scanning dose should be stable under certain parameter settings, but affected by factors such as environment and equipment status, the radiation scanning dose will fluctuate during actual radiological inspection, which is different from the rated radiation scanning dose. However, the conversion factor of the average single-pixel brightness and scanning dose when each device is factory-corrected without obstructions is fixed and stored in the device. Therefore, according to the average single-pixel brightness value in the scanned image when there is no obstruction, the actual scanning dose value can be obtained through the conversion of the conversion coefficient, reflecting the actual current personal radiation dose.

图3是被检查者接受检查的扫描图像的示意图。如图3所示，放射线扫描图像包括人体影像区51和除人体影像区51以外的残余像素区52。人体影像区51对应放射线被人体遮挡的区域(如果存在其它物体，也包括被其它物体遮挡的区域)，残余像素区52是无遮挡物时射线直接照射到探测器的区域。因为残余像素区52和人体同步被放射线照射，通过测量残余像素区52的单像素亮度，再根据执行检查的放射线检查设备的转换系数转换成对应的放射线剂量值，即可获得人体受照剂量值。FIG. 3 is a schematic diagram of a scanned image of an examinee undergoing examination. As shown in FIG. 3 , the radiographic scan image includes a humanbody image area 51 and aresidual pixel area 52 other than the humanbody image area 51 . The humanbody image area 51 corresponds to the area where the radiation is blocked by the human body (if there are other objects, it also includes the area blocked by other objects), and theresidual pixel area 52 is the area where the radiation directly irradiates the detector when there is no blocker. Since theresidual pixel area 52 and the human body are simultaneously irradiated with radiation, the human body exposure dose value can be obtained by measuring the single-pixel brightness of theresidual pixel area 52 and converting it into the corresponding radiation dose value according to the conversion coefficient of the radiation inspection equipment performing the inspection. .

进一步地，因为探测器组中的不同的探测器的测量值可能存在误差，因此，可以计算残余像素区52的各个像素的单像素亮度的平均值，将该单像素平均亮度值再转换成对应的放射线剂量。由于有足够多的残余像素参与平均，使得该均值非常稳定，可以正确地反映当次扫描的放射线输出剂量，因此能够精确反映当次扫描被检人员的受照剂量，避免因各种因素可能造成的设备输出剂量的波动带来的被检人员受照剂量的不正确记录。Further, since there may be errors in the measurement values of different detectors in the detector group, the average value of the single-pixel brightness of each pixel in theresidual pixel area 52 can be calculated, and the single-pixel average brightness value can be converted into corresponding values. radiation dose. Since there are enough residual pixels to participate in the averaging, the average value is very stable and can correctly reflect the radiation output dose of the current scan, so it can accurately reflect the radiation dose of the inspected person in the current scan, avoiding the possible cause by various factors. The fluctuation of the output dose of the equipment brings about the incorrect recording of the dose of the inspected person.

根据另外的实施例，如图1所示，放射线人体检查系统还可以包括个人放射线剂量计40，所述个人放射线计量计40在被检查者接收放射线检查时由被检查者同步携带，用于直接测量被检查者的单次放射线受照剂量。所述个人放射线计量计40可以和放射线人体检查设备12有线或无线通信，以将测量得到的单次放射线受照剂量发送给放射线人体检查设备12；或者，所述个人放射线计量计40可以和云端剂量信息服务器20直接通信，以将测量得到的单次放射线受照剂量直接上传至云端剂量信息服务器。具体地，可以在被检查者胸口或身旁与胸口相齐的位置放置一个个人放射线剂量计，个人放射线剂量计与被检人员同步接受放射线扫描，以直接测量被检查者的单次放射线受照剂量。According to another embodiment, as shown in FIG. 1 , the radiation human body examination system may further include a personal radiation dosimeter 40 , which is carried by the examinee synchronously when the examinee receives the radiation examination, and is used for direct Measure the single dose of radiation exposure of the examinee. The personal radiation meter 40 may communicate with the radiation humanbody examination apparatus 12 by wire or wirelessly, so as to transmit the measured single radiation exposure to the radiation humanbody examination apparatus 12; or, the personal radiation meter 40 may communicate with the cloud. Thedose information server 20 communicates directly, so as to directly upload the measured single radiation dose to the cloud dose information server. Specifically, a personal radiation dosimeter can be placed on the examinee's chest or at a position that is flush with the chest, and the personal radiation dosimeter and the examinee receive radiation scans synchronously to directly measure the examinee's single radiation exposure dose.

图4是利用如图1所示的放射线人体检查系统进行放射线人体检查的方法的流程图。如图4所示，根据本发明的一个实施例的检查过程包括：FIG. 4 is a flowchart of a method of performing a radiological human examination using the radiological human examination system shown in FIG. 1 . As shown in FIG. 4 , the inspection process according to an embodiment of the present invention includes:

在被检查者准备进入放射线人体检查设备的扫描通道时，首先，对待检查者进行个人身份登记或识别；When the examinee prepares to enter the scanning channel of the radiation human body examination equipment, firstly, register or identify the personal identity of the examinee;

根据身份识别结果调取被检查者的累积放射线受照剂量，例如年度累积放射线受照剂量；Obtain the cumulative radiation dose of the examinee according to the identification result, such as the annual cumulative radiation dose;

根据放射线人体检查设备类型获得如果进行本次检查将产生的预计举次放射线扫描剂量，该预计单次放射线扫描剂量可以是当前进行检查的放射线人体检查设备的额定放射线扫描剂量；Obtain the estimated radiation scan dose that will be generated if this examination is carried out according to the type of radiation body examination equipment, and the estimated single radiation scan dose may be the rated radiation scan dose of the radiation body examination equipment currently performing the examination;

将被检者本年度累积放射线受照剂量和预计单次放射线扫描剂量相加得到累加剂量值，根据所述累加值是否超过剂量限值来确定是否对被检查者执行本次放射线检查。The cumulative dose of radiation exposure of the subject in the current year and the expected dose of a single radiation scan are added to obtain a cumulative dose value, and whether to perform the current radiological examination on the subject is determined according to whether the cumulative value exceeds the dose limit.

具体地，如果累加剂量值超过预先设定的累计剂量限值，则决定不对被检查者进行当前放射线检查，以免被检查者接受过量的放射线辐射而损害身体健康。另一方面，如果被检者本年度累积放射线受照剂量和预计单次放射线扫描剂量相加得到的累加剂量值不超过预先设定的累计剂量限值，则确定开始对被检查者进行单次放射线检查。Specifically, if the accumulated dose value exceeds a preset accumulated dose limit, it is decided not to perform the current radiation examination on the examinee, so as to prevent the examinee from receiving excessive radiation radiation and damage to his health. On the other hand, if the cumulative dose value obtained by adding the cumulative radiation dose of the subject in the current year and the expected single radiation scan dose does not exceed the preset cumulative dose limit, it is determined to start a single dose of radiation on the subject. examine.

根据一个例子，所述累积放射线受照剂量可以是个人在一年内已经接受的放射线受照剂量的累积值，所述剂量限值可以是个人一年内可以接受的放射线受照剂量的上限值。According to an example, the cumulative radiation dose may be a cumulative value of radiation doses that an individual has received in one year, and the dose limit may be an upper limit of the radiation dose that an individual can receive in one year.

当确定对被检查者执行本次放射线检查时，在对被检查者执行放射线检查的过程中，可以实时监测放射线人体检查设备的输出参数，如果输出参数异常则中止检查工作；已经执行完成部分的放射线检查受照剂量，按已执行时间与完整执行检查所需时间比例折算本次非完整检查对被检查人员造成的放射线受照剂量。所述输出参数例如可以是放射线机的电压、电流、扫描速度等源项参数。如果在扫描过程中由于操作员操作失误或者设备故障等意外原因源项参数超出了设计值(异常)，则可能导致单次扫描剂量超出个人单次受照剂量限值，对人体造成危害，因此，在这种情况下，放射线检查设备停止发射放射线以中断扫描操作，并记录当次已经受照的剂量。否则，放射线检查设备正常完成本次扫描，并记录当次受照的剂量。When it is determined to perform this radiological examination on the subject, the output parameters of the radiation human body examination equipment can be monitored in real time during the process of performing the radiological examination on the subject. If the output parameters are abnormal, the examination will be terminated; The radiation dose of the radiation inspection shall be converted into the radiation dose of the inspected personnel caused by this incomplete inspection according to the proportion of the time that has been performed and the time required for the complete inspection. The output parameters may be, for example, source term parameters such as voltage, current, and scanning speed of the radiation machine. If the source item parameter exceeds the design value (abnormal) due to unexpected reasons such as operator error or equipment failure during the scanning process, the single scanning dose may exceed the individual single exposure dose limit, causing harm to the human body. Therefore, , in this case, the radiation inspection equipment stops emitting radiation to interrupt the scanning operation, and records the dose that has been irradiated at that time. Otherwise, the radiological examination equipment normally completes the scan and records the dose received at that time.

具体地，根据一个实施例，获取被检查者的本次放射线受照剂量包括：获取被检查者本次检查的放射线扫描图像；以及对所述放射线扫描图像进行处理，根据所述放射线扫描图像中除人体影像以外的残余像素区域的单像素平均亮度值，经转换系数转换后获得被检查者的本次放射线受照剂量。所述转换系数预先存储在放射线检查设备中。所述单像素平均亮度值是所述放射线扫描图像中除人体影像以外的残余像素区域的各像素的像素亮度值的平均值。Specifically, according to one embodiment, acquiring the current radiation exposure dose of the examinee includes: acquiring the radiographic scan image of the examinee for the current examination; and processing the radiographic scan image, according to the radiographic scan image The single-pixel average brightness value of the residual pixel area other than the human image is converted by the conversion coefficient to obtain the current radiation dose of the examinee. The conversion coefficients are stored in the radiation inspection apparatus in advance. The single-pixel average luminance value is an average value of pixel luminance values of each pixel in the residual pixel region other than the human body image in the radiographic scan image.

因为探测器组中的不同的探测器的测量值可能存在误差，因此，通过计算残余像素区的各个像素的单像素亮度的平均值，将该单像素平均亮度值再转换成对应的放射线剂量。由于有足够多的残余像素参与平均，使得该均值非常稳定，可以正确地反映当次扫描的放射线输出剂量，因此能够精确反映当次扫描被检人员的受照剂量，避免因各种因素可能造成的设备输出剂量的波动带来的被检人员受照剂量的不正确记录。Because there may be errors in the measurement values of different detectors in the detector group, by calculating the average value of the single-pixel brightness of each pixel in the residual pixel area, the single-pixel average brightness value is converted into a corresponding radiation dose. Since there are enough residual pixels to participate in the averaging, the average value is very stable and can correctly reflect the radiation output dose of the current scan, so it can accurately reflect the radiation dose of the inspected person in the current scan, avoiding the possible cause by various factors. The fluctuation of the output dose of the equipment brings about the incorrect recording of the dose of the inspected person.

根据该实施例的一个简化的例子，被检查者的本次放射线受照剂量Y可以按如下公式计算：According to a simplified example of this embodiment, the current radiation dose Y of the examinee can be calculated according to the following formula:

Y＝Y1·X/X1Y=Y1·X/X1

其中，X是放射线扫描图像中残余像素区域的单像素平均亮度值，Y1是放射线人体检查设备在本次人体检查时的额定单次放射线扫描剂量的值，X1是对应本次人体检查时的额定单次放射线扫描剂量的值，在无任何遮挡物时得到的扫描图像中的单像素亮度值。其中，X1和Y1可以是作为设备参数被预先存储在设备中的。Among them, X is the single-pixel average brightness value of the residual pixel area in the radiation scan image, Y1 is the value of the rated single radiation scan dose of the radiation body examination equipment during this body examination, and X1 is the rated value corresponding to this body examination. The value of a single radiation scan dose, the brightness value of a single pixel in the scanned image obtained when there is no obstruction. Wherein, X1 and Y1 may be pre-stored in the device as device parameters.

根据另外的实施例，获取被检查者的本次放射线受照剂量包括：简单地获取放射线人体检查设备在本次人体检查时的额定单次放射线扫描剂量，作为被检查者的本次放射线受照剂量。According to another embodiment, acquiring the current radiation exposure dose of the examinee includes: simply acquiring the rated single radiation scan dose of the radiation body examination equipment during the current body examination, as the current radiation exposure of the examinee dose.

根据另外的实施例，获取被检查者的本次放射线受照剂量包括：被检查者携带个人放射线剂量计同步接受放射线检查，通过个人计量计测量被检查者的本次放射线受照剂量。例如，在被检人员胸口或身傍与胸口相齐区位放置一个个人剂量计，个人剂量计与被检人员同步通过检查通道，并通过有线或无线与X线设备通信，个人放射线剂量计将每次扫描人体后受照剂量直接精确记录下来。According to another embodiment, acquiring the current dose of radiation exposure of the examinee includes: the subject carries a personal dosimeter to receive a radiation examination synchronously, and the personal dose meter is used to measure the current dose of radiation exposure of the examinee. For example, a personal dosimeter is placed on the subject's chest or at the same position as the chest. The personal dosimeter and the subject pass through the examination channel synchronously, and communicate with the X-ray equipment through wired or wireless communication. After the first scan of the human body, the exposure dose is directly and accurately recorded.

上述几种测量、计算被检人员受照剂量的方法可以单独使用，也可以几种方法同时使用；如几种方法同时使用，为保护被检人的健康，个人剂量管理统计时采用最大值计算。The above-mentioned methods for measuring and calculating the exposure dose of the inspected person can be used alone or at the same time; if several methods are used at the same time, in order to protect the health of the inspected person, the maximum value is used for the calculation of personal dose management statistics. .

最后，将上述方式测量、计算得到的被检人员的本次放射线受照剂量信息上传至云端剂量信息服务器，与剂量信息服务器中存储的个人累积放射线受照剂量值累加，以更新该被检人的个人累积放射线受照剂量。Finally, upload the current radiation exposure dose information of the inspected person measured and calculated in the above method to the cloud dose information server, and accumulate with the personal cumulative radiation exposure dose value stored in the dose information server to update the inspected person. individual cumulative radiation exposure.

以上实施例提出的放射线人体检查方法和检查系统，一方面可以防止误操作和设备故障导致的单次辐射剂量超标，更重要的是可以在年度累积剂量上进行监控和防护，因此，提高了放射线人体检查的安全性。The radiation human body inspection method and inspection system proposed in the above embodiments, on the one hand, can prevent the single radiation dose from exceeding the standard caused by misoperation and equipment failure, and more importantly, can monitor and protect the annual cumulative dose, therefore, the radiation dose is improved. Safety of human examination.

另外，由于根据单像素平均亮度值实时换算被检查者的当次实际放射线受照剂量，或者采用个人放射线剂量计实时测量被检查者的当次实际放射线受照剂量，因此，可以准确地获得被检查者的当次实际放射线受照剂量，进一步提高放射线人体检查的安全性。In addition, since the current actual radiation dose of the examinee is converted in real time according to the average brightness value of a single pixel, or the actual radiation dose of the examinee is measured in real time by using a personal radiation dosimeter, the current actual radiation dose of the examinee can be accurately obtained. The actual radiation dose received by the examiner at that time further improves the safety of the radiation body examination.

以上实施例中，所述年度累积放射线受照剂量是个人在一年内已经接受的放射线扫描剂量的累积值。所述剂量限值是个人一年内可以接受的放射线扫描剂量的上限值。放射线人体检查设备的预计单次放射线扫描剂量可取该放射线人体检查设备的额定单次放射线扫描剂量。但是，以上规定不是限制性的。例如，累积放射线扫描剂量可是个人在一个季度内已经接受的放射线扫描剂量的累积值。所述剂量限值是个人一个季度内可以接受的放射线扫描剂量的上限值。放射线人体检查设备的预计单次放射线扫描剂量可以取不同于额定单次放射线扫描剂量的其它适当的剂量值。本发明实施例的放射线人体检查系统可以用于多种类型的放射线人体检查领域，例如X射线、γ射线等需要进行健康监测的放射线。In the above embodiment, the annual cumulative radiation dose is the cumulative value of the radiation scanning dose that the individual has received within one year. The dose limit is the upper limit of the radiation scan dose that an individual can receive in one year. The estimated single radiation scan dose of the radiation body examination apparatus may take the rated single radiation scan dose of the radiation body examination apparatus. However, the above provisions are not restrictive. For example, the cumulative radiation scan dose may be the cumulative value of the radiation scan dose an individual has received over a quarter. The dose limit is the upper limit of the radiation scan dose that an individual can accept in a quarter. The estimated single radiation scan dose of the radiation human body examination apparatus may take other appropriate dose values other than the rated single radiation scan dose. The radiation human body inspection system of the embodiment of the present invention can be used in various types of radiation human body inspection fields, such as X-rays, gamma rays, and other radiations that require health monitoring.
