Description

Technical Field

[0001] The present invention relates to the field of medical irradiation, and in particular to a radiation protection training method and equipment for imaging departments to prevent radiation such as CT radiation. Background Art

[0002] The rapid development and widespread application of radiological diagnostic and therapeutic technologies have made radiation protection training increasingly important. However, the current teaching model, still dominated by traditional theoretical lectures, has significant limitations. For one thing, existing protective equipment is outdated and unable to realistically simulate dynamic radiation scenarios. Furthermore, the lack of effective practical training methods makes it difficult for trainees to master key protective skills. This current teaching model directly impacts training effectiveness, leading to weak protection awareness and non-standard operation among practitioners in actual work, potentially leading to serious radiation safety accidents.

[0003] The main difficulties currently faced by radiation protection training are: first, the teaching methods are single, overly dependent on PowerPoint presentations and static physical displays, and lack interactive and immersive training equipment; second, existing training cannot provide real-time dose monitoring and intelligent operation evaluation, and there is a lack of teaching feedback mechanism; third, some medical institutions are forced to adopt the alternative model of "on-the-job training" due to insufficient equipment resources, which not only increases the radiation exposure risk of trainees, but also makes it difficult to ensure the systematic and standardized training.

[0004] It's worth noting that pregnant women, as a particularly sensitive population during radiological examinations, face even stricter radiation protection requirements. Failure to adhere to standardized procedures by staff can have irreversible consequences for the health of both mother and child. Faced with current challenges in radiation protection education, such as a lack of teaching aids, monotonous formats, and outdated content, innovative solutions are urgently needed, including interactive simulation teaching aid systems, virtual reality experience devices, and intelligent mobile learning platforms. The implementation of these innovative measures will effectively improve the quality of radiation protection training, ultimately achieving the fundamental goal of reducing ionizing radiation exposure in pregnant women and safeguarding the health of both mother and child.

[0041] See also Figure 1 and Figure 2A radiation protection training device for an imaging department of the present invention includes: a human body model 100; a light sensor array 200 composed of a plurality of light sensor elements 201 mounted on the human body model 100; a display screen 300 disposed near the human body model 100 for displaying a human body irradiation area and training results; a radiation protection suit 700 covering a non-irradiated area or a human body protection area on the human body model 100; and a controller 400 for controlling the light sensor array 200 and the display screen 300 according to a radiation protection training plan, the controller 400 being configured to set the human body irradiation area according to the training plan, divide the light sensor array 200 into an irradiation sensor area 210 and a protection sensor area 220 according to the set human body irradiation area, detect light sensing signals from the protection sensor area 220 and the irradiation sensor area 210, and determine the training results based on the detection results of the light sensing signals.

[0042] The human body model 100 is a human-like physical module manufactured according to the size and shape of the human body. A plurality of grooves 101 for installing the light sensing elements 201 are densely distributed on the human body model 100 , so that each light sensing element 201 is installed in a corresponding groove of the human body model 100 .

[0043] See also Figure 4a and Figure 4b Each light sensor element 201 is composed of a light-emitting element 2011 (e.g., a light-emitting diode) and a light-sensitive element 2012 (e.g., a photodiode) for generating a light-sensing signal. When the radiation protection suit 700 covers the light sensor element 201, the light emitted by the light-emitting element 2011 is blocked by the radiation protection suit 700 and reflected onto the light-sensitive element 2012, thereby generating a light-sensing signal. When the radiation protection suit 700 is not covering the light sensor element 201, the light emitted by the light-emitting element 2011 cannot be reflected, so the light-sensitive element 2012 is not illuminated and thus cannot generate a light-sensing signal.

[0044] See also Figure 3a The first embodiment of the controller 400 of the imaging radiation protection training device of the present invention includes: a human body irradiation area setting module 410, which is used to generate human body irradiation area information corresponding to an input instruction; a planning module 420 that divides the light sensor array 200 located on the human body model 100 into an irradiation sensor area 210 and a protection sensor area 220 according to the set human body irradiation area information; a detection module 430 that detects light sensing signals of the protection sensor area 220 and the irradiation sensor area 210 respectively after the trainee covers the human body model 100 with radiation protection clothing 700 according to the human body irradiation area displayed on the display screen 300 based on the human body irradiation area information; and a training result determination module 440 that determines and outputs a training result to the display screen 300 based on the detection results of the detection module 430 that detects the light sensing signals of the protection sensor area 220 and the irradiation sensor area 210 respectively.

[0045] See also Figure 7 The planning module 420 of the controller 400 of the present invention includes: an address allocation unit 4201, which is used to allocate a unique address to each light sensor element 201 in the light sensor array 200; a light sensor area division unit 4202, which is used to divide the light sensor array 200 located on the human body model 100 into an irradiation sensor area 210 and a protection sensor area 220 according to the set human body irradiation area information; and a light sensor element determination unit 4203, which is used to determine the irradiation sensor element group 2101 corresponding to the irradiation sensor area 210 and the protection sensor element group 2201 corresponding to the protection sensor area 220, and send their addresses to the detection module 430.

[0046] In one embodiment, the human body irradiation area setting module 410 can also generate a control instruction to power on the light sensor array 200 according to the training start instruction issued by the trainer. Alternatively, the trainer can also power on the light sensor array 200 by turning off the power switch.

[0047] The detection module 430 detects the light-sensitive signals of the irradiation sensor group 2101 and the protection sensor group 2201 according to the irradiation sensor group 2101 and the protection sensor group 2201 determined by the light sensor determination unit 4203 and the unique address assigned to each light sensor unit by the address allocation unit 4201, and sends the detection results to the training result determination module 440.

[0048] The detection results may include a first light-sensing signal generated by the irradiation sensor element 2101 when the radiation protection suit 700 covers the irradiation sensor element 2101, and a second light-sensing signal generated by the protection sensor element 2201 when the radiation protection suit 700 covers the protection sensor element 2201. The training performance determination module 440 determines a failing training result upon receiving the first light-sensing signal, as the first light-sensing signal is generated by the trainee mistakenly covering the radiation protection suit 700 with the irradiation sensor element 2101 located in the irradiation area. The training performance determination module 440 determines a passing training result upon receiving the second light-sensing signal but not the first light-sensing signal.

[0049] Figure 3bThe second embodiment of the controller 400 for the radiology radiation protection training device of the present invention is shown, comprising: a human irradiation area setting module 410 for generating human irradiation area information corresponding to an input instruction; a planning module 420 for dividing the light sensor array 200 located on the mannequin 100 into an irradiation sensor area 210 and a protection sensor area 220 based on the set human irradiation area information; a detection module 430 for detecting light signals from the protection sensor area 220 and the irradiation sensor area 210 after the trainee covers the mannequin 100 with radiation protection clothing 700 according to the human irradiation area displayed on the display screen 300 based on the human irradiation area information; and a training result determination module 440 for determining and outputting a training result to the display screen 300 based on the detection results of the detection module 430 for detecting light signals from the protection sensor area 220 and the irradiation sensor area 210. The second embodiment of the controller 400 differs from the first embodiment in that it also includes an irradiation area preset module 450 for storing the correspondence between conventional human irradiation areas and irradiation sensor areas 210.

[0050] After receiving the set human body irradiation area information, the planning module 420 searches the irradiation area preset module 450 for a correspondence between the conventional human body irradiation area and the irradiation sensor area 210. Based on the found correspondence, the light sensor array 200 located on the human body model 100 is divided into the irradiation sensor area 210 and the protection sensor area 220. If the planning module 420 does not find a correspondence between the human body irradiation area and the irradiation sensor area 210 in the irradiation area preset module 450, the light sensor array 200 located on the human body model 100 is divided into the irradiation sensor area 210 and the protection sensor area 220 based on the set human body irradiation area information.

[0051] Figure 5a The optical sensor array 200 of the present invention is shown to be composed of multiple optical sensor elements 201; the address allocation unit 4201 of the planning module 420 allocates a unique address and coordinates to each optical sensor element 201; the coordinates of the optical sensor element 201 correspond to the coordinates of the human body model one by one. Figure 5a The light sensor element in the lower left corner is assigned address 0001, and its coordinates are the human body model coordinates (0,0); Figure 5a The light sensor element in the upper left corner is assigned address 0012, and its coordinates are the human body model coordinates (0,12); Figure 5a The light sensor element in the lower right corner is assigned address 0216, and its coordinates are the human body model coordinates (18,0); Figure 5aThe light sensor element in the upper right corner is assigned address 0204, and its coordinates are the human body model coordinates (18, 12). The address assignment unit 4201 stores the mapping relationship between the address and coordinates of each light sensor element 201, or a mapping table. The address assignment unit 4201 sends the mapping relationship between the address and coordinates of each light sensor element 201 to the light sensor element determination unit 4203.

[0052] The human body irradiation area information generated by the irradiation area setting module 410 includes conventional medical irradiation areas such as chest irradiation area, lung irradiation area, liver irradiation area, stomach irradiation area, etc., as well as irradiation area information represented by human body model coordinates.

[0053] The irradiation area preset module 450 can pre-set the mapping relationship between the conventional medical irradiation area and the light sensor elements 201 located in the irradiation area. For example, a mapping relationship is established between the chest irradiation area and the light sensor elements 201 with addresses 0001 to 0096. In this way, the planning module 420 can obtain the mapping relationship between the chest irradiation area and the sensor elements 201 in the area from the irradiation area preset module 450 based on the chest irradiation area information from the irradiation area setting module 410. The light sensor element determination unit then uses the mapping relationship to determine the light sensor elements 201 with addresses 0001 to 0096 as the irradiation sensor element group 2101, and determine the other light sensor elements of the light sensor array 200 as the protection sensor elements 2201 corresponding to the protection sensor area 220.

[0054] If the irradiation area information from the irradiation area setting module 410 is not conventional irradiation area information (such as Figure 6a The light sensing area dividing unit 4202 determines the irradiation area 210 and the protection area 220 according to the irradiation area information, and sends the coordinate information of the human body model in the irradiation area 210 to the light sensing element determining unit 4203, so that the light sensing element determining unit 4203 determines all the light sensing elements 201 in the area as the irradiation sensing element group 2101 and determines all the light sensing elements 201 outside the area as the protection sensing element group 2201 according to the mapping relationship between the address and coordinates of each light sensing element 201 stored therein.

[0055] It should be pointed out that Figure 3aThe first embodiment of the controller for the radiology radiation protection training device shown is suitable for training without pre-setting a conventional mapping relationship between medical irradiation areas and the light sensor elements 201 located in the irradiation area. Specifically, the light sensor area division unit 4202 determines the irradiation area 210 and the protection area 220 based on the irradiation area information (i.e., the irradiation area coordinate information). The coordinate information of the human body model in the irradiation area 210 is sent to the light sensor element determination unit 4203. The light sensor element determination unit 4203, based on the stored mapping relationship between the address and coordinates of each light sensor element 201, determines all light sensor elements 201 in the area as the irradiation sensor element group 2101, and determines all light sensor elements 201 outside the area as the protection sensor elements 2201. Then the address of the irradiation sensor tuple 2101 and the address of the protection sensor tuple 2201 are sent to the detection module 430, so that the detection module 430 detects the photosensitive signal of the irradiation sensor tuple 2101 and the photosensitive signal of the protection sensor tuple 2201 according to the address of the irradiation sensor tuple 2101 and the address of the protection sensor tuple 2201 respectively, and sends the detection results to the training result determination module.

[0056] Figure 3b The second embodiment of the controller for the radiology radiation protection training device shown in the figure has better training effects. The irradiation area presetting module 450 can pre-set the mapping relationship between the conventional medical irradiation area and the light sensor elements 201 located in the irradiation area. This allows the planning module 420 to obtain the mapping relationship between the irradiation area and the light sensor elements 201 from the irradiation area presetting module 450 based on the irradiation area information from the irradiation area setting module 410, thereby determining the irradiation sensor element group 2101 and the protection sensor element group 2201. Then, based on the address assigned to each light sensor element 201, the address of the irradiation sensor element group 2101 and the address of the protection sensor element group 2201 are determined and sent to the detection module 430. If the illumination area information is not conventional, the light sensing area division unit 4202 determines the illumination area 210 and the protection area 220 based on the illumination area coordinate information. The coordinate information of the human body model in the illumination area 210 is then sent to the light sensing element determination unit 4203. This unit then determines all light sensing elements 201 in the illumination area as illumination sensor element groups 2101, and all light sensing elements 201 outside the illumination area as protection sensor elements 2201, based on the stored mapping relationship between the address and coordinates of each light sensing element 201. The addresses of the illumination sensor element groups 2101 and the protection sensor element groups 2201 are then sent to the detection module 430. The detection module 430 detects the light sensing signals of the illumination sensor element groups 2101 and the protection sensor element groups 2201, respectively, based on the addresses of the illumination sensor element groups 2101 and the protection sensor element groups 2201, and sends the detection results to the training performance determination module.

[0057] Figure 5b The diagram shows a trainee placing radiation protection suit 700 over protection sensing area 220. When planning module 420 divides light sensor array 200 into irradiation sensing area 210 and protection sensing area 220, it starts a timer to wait for the trainee to place radiation protection suit 700 over protection sensing area 220. After the timer expires, planning module 420 instructs detection unit 430 to detect the light signals of irradiation sensor element 2101 in irradiation sensing area 210 and the light signals of protection sensor element 2201 in protection sensing area 220.

[0058] Figure 6a and Figure 6b The situation where multiple radiation protection suits 700 are needed to cover the protection sensing area 220 is shown. Figure 6a When the middle part of the human body module is shown, multiple radiation protection suits such as the first radiation protection suit 700-1, the second radiation protection suit 700-2, the third radiation protection suit 700-3 and the fourth radiation protection suit 700-4 are needed to cover the protection sensing area 220 so as to expose only the irradiation sensing area 210 in the middle.

[0059] The training process of the present invention is as follows: the trainer inputs a training plan (i.e., a human model irradiation area) through an irradiation area setting module (e.g., a computer). The irradiation area setting module 410 transmits the training plan to the display screen 300 and the planning module 420, respectively. The planning module 420 divides the light sensor array 700 into an irradiation sensing area 210 and a protection sensing area 220 according to the training plan. The planning module 420 obtains the addresses of all light sensor elements 201 in the irradiation sensing area 210 (i.e., an irradiation sensor element group 2101) based on the human model coordinates in the irradiation area 210 and the mapping relationship between the address of each light sensor element 201 and the human model coordinates. The trainee then covers the protection area 220 with the radiation protection suit 700 based on the human model irradiation area displayed on the display screen. Planning module 420 then sends the addresses of irradiation sensor tuple 2101 and protection sensor tuple 2201 to detection module 430, so that detection module 430 detects the light-sensing signal of irradiation sensor tuple 2101 according to the address of irradiation sensor tuple 2101 and detects the light-sensing signal of protection sensor tuple 2201 according to the address of protection sensor tuple 2201. The training result determination module determines the training result based on the detection results and displays the training result on display screen 300.

[0060] The detection results include a first light-sensing signal generated by the irradiation sensor element 2101 when the radiation protection suit 700 covers the irradiation sensor element 2101, and a second light-sensing signal generated by the protection sensor element 2201 when the radiation protection suit 700 covers the protection sensor element 2201. Upon receiving the first light-sensing signal, the training performance determination module 440 determines that the training failed because the first light-sensing signal was generated by the trainee mistakenly covering the radiation protection suit 700 with the irradiation sensor element 2101 located in the irradiation area. Upon receiving the second light-sensing signal but not the first light-sensing signal, the training performance determination module 440 determines that the training passed because the trainee covered the radiation protection suit 700 with the protection sensor element 2201 and did not cover the irradiation sensor element 2101.

[0061] Figure 3c The third embodiment of the controller of the imaging department radiation protection training device is shown. The third embodiment can be used specifically for radiation protection training for pregnant women and children. The third embodiment of the controller 400 includes: a radiation protection area setting module 460, which is used to generate radiation protection area information corresponding to the input instruction; a radiation protection area preset module 470, which is used to obtain the address of the protection sensor tuple 2201 and the address of the irradiation sensor tuple 2101 according to the radiation protection area information from the radiation protection area setting module 460 and the preset mapping relationship between the radiation protection area and the address of the protection sensor tuple 2201; a detection module 430, which is used to detect the light-sensitive signal of the protection sensor tuple 2201 and the light-sensitive signal of the irradiation sensor tuple 2101 respectively after the trainee covers the radiation protection area of ​​the human body model 100 with the radiation protection suit 700 according to the radiation protection area displayed on the display screen 300; and a training result determination module 440 for determining the training result according to the detection results of the light-sensitive signal of the protection sensor tuple 2201 and the irradiation sensor tuple 2101.

[0062] Figure 3c The radiation protection area preset module 470 in the embodiment stores the radiation protection area information of the fetus at different stages of pregnancy, such as Figure 8a The radiation protection zone information for the fetus during the third trimester is shown. Figure 8bThe radiation protection zone information for a fetus at six months of gestation is shown. The radiation protection zone presetting module 470 pre-establishes a mapping relationship between the radiation protection zones 220 for fetuses at different gestational stages and the addresses of their protection sensor tuples 2201. After the radiation protection zone setting module 460 outputs the fetal protection zone information for a specific gestational stage to the radiation protection zone presetting module 470 and the display screen 300, the radiation protection zone presetting module 470 obtains the addresses of the protection sensor tuples 2201 and the irradiation sensor tuples 2101 (i.e., the addresses of all light sensor tuples 201 remaining after removing the address of the protection sensor tuple 2201 from all light sensor tuple addresses) based on the pre-established mapping relationship between the radiation protection zones 220 for fetuses at different gestational stages and the addresses of their protection sensor tuples 2201. The obtained addresses of the protection sensor tuples 2201 and irradiation sensor tuples 2101 are then sent to the detection module 430. At the same time, the trainee covers the specific fetal protection zone for the specific pregnancy period with radiation protective clothing 700, based on the information displayed on the display screen. This allows the detection module 430 to detect the light-sensing signal of the protection sensor tuple 2201 and the light-sensing signal of the irradiation sensor tuple 2101, respectively, based on the addresses of the protection sensor tuple 2201 and the irradiation sensor tuple 2101, and transmits the detection results to the training achievement determination module 440. If the detection result shows that the light-sensing signal of the protection sensor tuple 2201 is detected but the light-sensing signal of the irradiation sensor tuple 2101 is not detected, the training achievement determination module 440 determines that the training achievement is satisfactory. If the detection result shows that the light-sensing signal of the protection sensor tuple 2201 is not detected, the training achievement determination module 440 determines that the training achievement is unsatisfactory. The achievement determination module 440 transmits the determined training achievement to the display screen 300 for display.

[0063] also, Figure 3cThe radiation protection zone presetting module 470 also stores child radiation protection zone information. The radiation protection zone presetting module 470 pre-establishes a mapping relationship between the radiation protection zones 220 for children of different ages and the addresses of their protection sensor tuples 2201. After the radiation protection zone setting module 460 outputs the specific child protection zone information to the radiation protection zone presetting module 470 and the display screen 300, the radiation protection zone presetting module 470 obtains the addresses of the protection sensor tuples 2201 and the irradiation sensor tuples 2101 based on the pre-established mapping relationship between the radiation protection zones 220 for children of different ages and the addresses of their protection sensor tuples 2201, and sends the obtained addresses of the protection sensor tuples 2201 and irradiation sensor tuples 2101 to the detection module 430. At the same time, the trainee covers the specific child protection area with radiation protection suit 700 according to the specific child protection area information displayed on the display screen. This allows the detection module 430 to detect the light-sensing signals of the protection sensor tuple 2201 and the irradiation sensor tuple 2101 based on the addresses of the protection sensor tuple 2201 and the irradiation sensor tuple 2101, and transmits the detection results to the training performance determination module 440. If the detection result shows that the light-sensing signal of the protection sensor tuple 2201 is detected but the light-sensing signal of the irradiation sensor tuple 2101 is not detected, the training performance determination module 440 determines that the training performance is satisfactory. If the detection result shows that the light-sensing signal of the protection sensor tuple 2201 is not detected, the training performance determination module 440 determines that the training performance is unsatisfactory. The performance determination module 440 transmits the determined training performance to the display screen 300 for display.
