Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of CT scanning and related technical fields, in particular, to a CT detector assembly method, device, equipment and storage medium. BACKGROUND

[0002] In the mainstream CT scanning system of modern medicine, the detector, as a device for collecting image data in the CT scanning system, plays a crucial role in the entire system. In the CT scanning system, the X-ray tube emits X-rays, which fully cover a certain part of the human body to be scanned. The detector collects X-rays and converts them into electrical signals, which are then converted into digital information by a data acquisition and conversion unit and stored in an image processing system. The image processing system generates images through a series of correction algorithms and image reconstruction algorithms and displays them on a display.

[0003] In the CT scanning system, the detector is a photosensitive array formed by photosensitive crystals. The photosensitive array is installed on a photosensitive module mounting sheet, which is installed on a photosensitive module mounting frame, and finally assembled into a whole detector. Because the photosensitive module mounting frame and the photosensitive module mounting sheet are mechanical parts, there will be machining errors. In order to ensure image quality, the error between adjacent photosensitive module mounting frames cannot be too large, and the error after matching the photosensitive module mounting sheet and the photosensitive module mounting frame cannot be too large. The current mainstream detector debugging is based on the assumption that all photosensitive module mounting sheets and photosensitive module mounting frames have ideal errors. Then, a detector is randomly assembled, and scanning is performed after being connected to a machine. If there is an error, the photosensitive module mounting sheet is replaced. This debugging method is time-consuming, wastes manpower, and the photosensitive module mounting sheet and the photosensitive module mounting frame are difficult to trace and manage. SUMMARY

[0062] Based on the problems existing in the prior art, the present application provides a CT detector assembly method, in the process of assembling the CT detector, first, the position information of the first positioning hole in each photosensitive module installation slot in the photosensitive module installation frame unit and the position information of the second positioning hole in each photosensitive module installation piece are acquired, wherein the position information of the first positioning hole in each photosensitive module installation slot in the photosensitive module installation frame unit and the position information of the second positioning hole in each photosensitive module installation piece can be confirmed after the photosensitive module installation slot is prepared and formed and the photosensitive module installation piece is prepared and formed. The corresponding data is stored in the database.

[0063] Due to the preparation process error, the position information of the first positioning hole in each photosensitive module installation slot of the photosensitive module installation frame unit and the position information of the second positioning hole in each photosensitive module installation piece are deviated, so that during the embedding of the photosensitive module installation piece and the photosensitive module installation slot, the photosensitive module installation piece and the photosensitive module installation slot with approximately the same error precision need to be selected to ensure that the photosensitive module installation piece and the photosensitive module installation slot can be perfectly embedded, and in addition, when arranging the photosensitive module installation frame unit, the adjacent two photosensitive module installation frame units also need to have the same error precision, therefore, in the CT detector assembly method provided by the embodiment of the present disclosure, the position information of the first positioning hole in each photosensitive module installation slot of the photosensitive module installation frame unit and the position information of the second positioning hole in each photosensitive module installation piece are first acquired.

[0064] In the CT detector assembly process, the photosensitive module installation frame unit in the photosensitive module installation frame needs to be sorted first, and in the sorting process of the photosensitive module installation frame unit, a photosensitive module installation frame unit is first selected as a reference photosensitive module installation frame unit, and then other photosensitive module installation frame units except the reference photosensitive module installation frame unit are matched with the reference photosensitive module installation frame unit to determine the specific arrangement mode of the other photosensitive module installation frame units relative to the reference photosensitive module installation frame, therefore, in the embodiment of the present disclosure, after a photosensitive module installation frame unit is selected as a reference photosensitive module installation frame unit, the other photosensitive module installation frame units except the reference photosensitive module installation frame unit are matching photosensitive module installation frame units.

[0067] Specifically, after the reference photosensitive module installation unit and the matching photosensitive module installation frame unit are determined, according to the position information of the first positioning hole in each photosensitive module installation slot in each matching photosensitive module installation frame unit and the position information of the first positioning hole in each photosensitive module installation slot in the reference photosensitive module installation frame unit, the arrangement mode of each matching photosensitive module installation frame unit relative to the reference photosensitive module installation frame unit is determined.

[0068] In a specific implementation, the position information of the first positioning hole in each of the photomodule mounting slots in each of the matching photomodule mounting frame units and the position information of the first positioning hole in each of the photomodule mounting slots in the reference photomodule mounting frame unit are used to determine the arrangement mode of each of the matching photomodule mounting frame units relative to the reference photomodule mounting frame unit, including: the position information of the first positioning hole in each of the photomodule mounting slots in each of the matching photomodule mounting frame units and the position information of the first positioning hole in each of the photomodule mounting slots in the reference photomodule mounting frame unit are used to calculate the matching score of each of the matching photomodule mounting frame units in sequence; the matching score of each of the matching photomodule mounting frame units is used to determine a target matching photomodule mounting frame unit arranged adjacent to the reference photomodule mounting frame unit; the position information of the first positioning hole in each of the photomodule mounting slots in each of the matching photomodule mounting frame units except the reference photomodule mounting frame unit and the target matching photomodule mounting frame unit and the position information of the first positioning hole in each of the photomodule mounting slots in the target matching photomodule mounting frame unit are used to determine a target matching photomodule mounting frame unit arranged adjacent to the target matching photomodule mounting frame unit.

[0069] The photomodule mounting frame unit includes N photomodule mounting slots arranged along a first direction, and each of the photomodule mounting slots includes two first positioning holes.

[0070] The position information of the first positioning hole in each of the photomodule mounting slots in each of the matching photomodule mounting frame units and the position information of the first positioning hole in each of the photomodule mounting slots in the reference photomodule mounting frame unit are used to calculate the matching score of each of the matching photomodule mounting frame units in sequence, including: the position information of the first positioning hole in each of the photomodule mounting slots in each of the matching photomodule mounting frame units and the position information of the first positioning hole in each of the photomodule mounting slots in the reference photomodule mounting frame unit are used to calculate the sub-matching score of each of the photomodule mounting slots in each of the matching photomodule mounting frame units in sequence; and the sub-matching score of each of the photomodule mounting slots in each of the matching photomodule mounting frame units is used to determine the matching score of each of the matching photomodule mounting frame units.

First, the error information of the first light-sensitive module installation slot arranged along the first direction of the reference light-sensitive module installation frame unit is determined according to the relationship between the position information of the first positioning hole in the first light-sensitive module installation slot and the preset position information, and then the error information of the second light-sensitive module installation slot arranged along the first direction of the reference light-sensitive module installation frame unit is calculated, and so on, until the error information of the Nth light-sensitive module installation slot arranged along the first direction of the reference light-sensitive module installation frame unit is calculated.

In addition, the error information of the first light-sensitive module installation slot arranged along the first direction of the Mth matching light-sensitive module installation frame unit is calculated according to the relationship between the position information of the first positioning hole in each light-sensitive module installation slot arranged along the first direction of the Mth matching light-sensitive module installation frame unit and the preset position information, and then the error information of the second light-sensitive module installation slot arranged along the first direction of the Mth matching light-sensitive module installation frame unit is calculated, and so on, until the error information of the Nth light-sensitive module installation slot arranged along the first direction of the Mth matching light-sensitive module installation frame unit is calculated.

[0073] After the error information of the N photosensitive module installation slots arranged along the first direction of the reference photosensitive module installation frame unit and the error information of the N photosensitive module installation slots arranged along the first direction of each matching photosensitive module installation frame unit are determined, the matching scores of the reference photosensitive module installation frame unit and each matching photosensitive module installation frame unit are calculated in sequence, the matching photosensitive module installation frame unit with the highest matching score is selected as the target matching photosensitive module installation frame unit arranged adjacent to the reference photosensitive module installation frame unit, and so on, the target matching photosensitive module installation frame unit arranged adjacent to the reference photosensitive module installation frame unit is taken as the reference photosensitive module installation frame unit, the matching score calculation is performed again between the target matching photosensitive module installation frame unit and the remaining matching photosensitive module installation frame units, and the target matching photosensitive module installation frame unit adjacent to the target matching photosensitive module installation frame unit is determined again until the arrangement of M-1 matching photosensitive module installation frame units is completed.

[0074] After the error information of the N photosensitive module installation slots arranged along the first direction of the reference photosensitive module installation frame unit and the error information of the N photosensitive module installation slots arranged along the first direction of each matching photosensitive module installation frame unit are determined, the matching scores of the reference photosensitive module installation frame unit and each matching photosensitive module installation frame unit are calculated in sequence, the matching photosensitive module installation frame unit with the highest matching score is selected as the target matching photosensitive module installation frame unit arranged adjacent to the reference photosensitive module installation frame unit, and so on, the target matching photosensitive module installation frame unit arranged adjacent to the reference photosensitive module installation frame unit is taken as the reference photosensitive module installation frame unit, the matching score calculation is performed again between the target matching photosensitive module installation frame unit and the remaining matching photosensitive module installation frame units, and the target matching photosensitive module installation frame unit adjacent to the target matching photosensitive module installation frame unit is determined again until the arrangement of M-1 matching photosensitive module installation frame units is completed.

[0075] In a specific example, the specific process of determining the error information of the first photosensitive module installation slot of the first matching photosensitive module installation frame unit arranged along the first direction according to the error information of the first photosensitive module installation slot of the reference photosensitive module installation frame unit arranged along the first direction and the error information of the first photosensitive module installation slot of the first matching photosensitive module installation frame unit arranged along the first direction is as follows: the error information of the first photosensitive module installation slot of the reference photosensitive module installation frame unit arranged along the first direction is D1, the direction is positive, the error information of the first photosensitive module installation slot of the first matching photosensitive module installation frame unit arranged along the first direction is D2, the direction is negative, then the error information of the first photosensitive module installation slot of the first matching photosensitive module installation frame unit arranged along the first direction is |D1-D2|, then according to the error range interval where the error information is located and the arrangement position of the photosensitive module installation slot corresponding to the error information, the sub-matching score of the first photosensitive module installation slot in the matching photosensitive module installation frame unit is determined, and so on, so as to determine the sub-matching scores of the photosensitive module installation slots in the matching photosensitive module installation frame unit.

[0076] It should be noted that the photosensitive module installation slots at different arrangement positions correspond to different matching weight values.

[0077] After determining the matching scores of the matching photosensitive module installation frame units, the matching photosensitive module installation frame unit with the maximum matching score is selected as the target matching photosensitive module installation frame unit arranged adjacent to the reference photosensitive module installation frame unit, and then the target matching photosensitive module installation frame unit arranged adjacent to the reference photosensitive module installation frame unit is taken as the reference photosensitive module installation frame unit, the matching scores of the remaining matching photosensitive module installation frame units are calculated by the above method, the target matching photosensitive module installation frame unit adjacent to the target matching photosensitive module installation frame unit is determined again, until the arrangement of M-1 matching photosensitive module installation frame units is completed, and after the arrangement of M-1 matching photosensitive module installation frame units is completed, the arranged reference photosensitive module installation frame unit and the matching photosensitive module installation frame unit form the target photosensitive module installation frame.

[0078] It should be noted that in the above embodiment, the specific process of determining the error information of the N light-sensitive module installation slots arranged along the first direction in the light-sensitive module installation frame unit is as follows: first, according to the position information of the first positioning hole in each light-sensitive module installation slot in the light-sensitive module installation frame unit, the center position information of each light-sensitive module installation slot in the light-sensitive module installation frame unit can be determined, and according to the relationship between the center position information of each light-sensitive module installation slot in the light-sensitive module installation frame unit and the preset position information, the error information of each light-sensitive module installation slot in the light-sensitive module installation frame unit is determined, wherein the positive and negative values in the error information reflect the error direction, and the deviation value in the error information reflects the error size.
