Description

Technical Field

[0001] This invention relates to the field of CT scanning technology and related technical fields, specifically to a CT detector assembly method, apparatus, device, and storage medium. Background Technology

[0002] In modern mainstream CT scanning systems, the detector plays a crucial role as the device that acquires image data. In a CT scanning system, the X-ray tube emits X-rays that cover a specific part of the human body to be scanned. The detector acquires the X-rays and converts them into electrical signals. These signals are then converted into digital information by the data acquisition and conversion unit and stored in the image processing system. The image processing system then uses a series of correction and image reconstruction algorithms to generate an image that is displayed on the monitor.

[0003] In a CT scanning system, the detector consists of a photosensitive array made up of photosensitive crystals. This array is mounted on a photosensitive module mounting plate, which in turn is mounted on a photosensitive module mounting frame, ultimately assembling into a single detector. Because both the photosensitive module mounting frame and the photosensitive module mounting plate are mechanical parts, manufacturing errors are inevitable. To ensure image quality, the error between adjacent photosensitive module mounting frames cannot be too large, nor can the error after matching the photosensitive module mounting plate to the frame be too large. Currently, mainstream detector calibration methods assume that all photosensitive module mounting plates and frames have ideal errors. They then randomly assemble a detector, scan it, and replace the problematic mounting plate. This calibration process is time-consuming, wastes manpower, and makes it difficult to trace and manage the photosensitive module mounting plates and frames. Summary of the Invention

[0026] In view of the problems existing in the prior art, the present disclosure provides a CT detector assembly method. Figure 1 This is a schematic flowchart of a CT detector assembly method provided in an embodiment of this disclosure, as shown below. Figure 1 As shown, the specific process of CT detector assembly includes: S110. Obtain the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece in the photosensitive module mounting frame unit.

[0027] Specifically, CT detectors include M N photosensitive module mounting pieces and photosensitive module mounting frames, the photosensitive module mounting frames comprising M photosensitive module mounting frame units arranged along a second direction, each photosensitive module mounting frame unit comprising N photosensitive module mounting slots arranged along a first direction, each photosensitive module mounting slot comprising two first positioning holes, each photosensitive module mounting piece unit comprising two second positioning holes, the photosensitive module mounting pieces and photosensitive module mounting frames being fitted together. Figure 2 An exemplary schematic diagram of the photosensitive module mounting frame is shown.

[0028] Based on the problems existing in the prior art, this disclosure provides a CT detector assembly method. During the CT detector assembly process, the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece in the photosensitive module mounting frame unit are first obtained. The position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece in the photosensitive module mounting frame unit can be confirmed after the photosensitive module mounting slot and the photosensitive module mounting piece are formed, and the corresponding data is stored in a database.

[0029] Due to manufacturing process errors, there are deviations in the position information of the first positioning holes in each photosensitive module mounting slot and the position information of the second positioning holes in each photosensitive module mounting piece within the fabricated photosensitive module mounting frame unit. Therefore, during the fitting process of the photosensitive module mounting pieces and photosensitive module mounting slots, it is necessary to select photosensitive module mounting pieces and photosensitive module mounting slots with approximately the same error accuracy to ensure that the photosensitive module mounting pieces and photosensitive module mounting slots can fit perfectly. In addition, when arranging the photosensitive module mounting frame units, it is also necessary to ensure that adjacent photosensitive module mounting frame units have the same error accuracy. Therefore, in the CT detector assembly method provided in this embodiment, the position information of the first positioning holes in each photosensitive module mounting slot and the position information of the second positioning holes in each photosensitive module mounting piece are first obtained within the photosensitive module mounting frame unit.

[0030] S120. Select one photosensitive module mounting frame unit as the reference photosensitive module mounting frame unit, and select other photosensitive module mounting frame units as matching photosensitive module mounting frame units.

[0031] During the assembly of a CT detector, the first step is to sort the photosensitive module mounting frame units within the photosensitive module mounting frame. In this sorting process, a photosensitive module mounting frame unit is first selected as the reference photosensitive module mounting frame unit. Then, by matching the other photosensitive module mounting frame units (excluding the reference photosensitive module mounting frame unit) with the reference photosensitive module mounting frame unit, the specific arrangement of the other photosensitive module mounting frame units relative to the reference photosensitive module mounting frame is determined. Therefore, in this embodiment, after selecting a photosensitive module mounting frame unit as the reference photosensitive module mounting frame unit, the other photosensitive module mounting frame units (excluding the reference photosensitive module mounting frame unit) are the matched photosensitive module mounting frame units.

[0032] S130. Based on the position information of the first positioning hole in each photosensitive module mounting slot in each matching photosensitive module mounting frame unit and the position information of the first positioning hole in each photosensitive module mounting slot in the reference photosensitive module mounting frame unit, determine the arrangement of each matching photosensitive module mounting frame unit relative to the reference photosensitive module mounting frame unit, and generate the target photosensitive module mounting frame.

[0033] Specifically, after determining the reference photosensitive module mounting unit and the matching photosensitive module mounting frame unit, the arrangement of each matching photosensitive module mounting frame unit relative to the reference photosensitive module mounting frame unit is determined based on the position information of the first positioning hole in each photosensitive module mounting slot in each matching photosensitive module mounting frame unit and the position information of the first positioning hole in each photosensitive module mounting slot in the reference photosensitive module mounting frame unit.

[0034] In the specific implementation, based on the position information of the first positioning holes in the mounting slots of each matching photosensitive module in each matching photosensitive module mounting frame unit and the position information of the first positioning holes in the mounting slots of each photosensitive module in the reference photosensitive module mounting frame unit, the arrangement of each matching photosensitive module mounting frame unit relative to the reference photosensitive module mounting frame unit is determined. This includes: based on the position information of the first positioning holes in the mounting slots of each matching photosensitive module in each matching photosensitive module mounting frame unit and the position information of the first positioning holes in the mounting slots of each photosensitive module in the reference photosensitive module mounting frame unit, the arrangement of each matching photosensitive module mounting frame unit relative to the reference photosensitive module mounting frame unit is calculated sequentially. The matching score of each unit; based on the matching score of each matching photosensitive module mounting frame unit, the target matching photosensitive module mounting frame unit arranged adjacent to the reference photosensitive module mounting frame unit is determined; based on the position information of the first positioning hole in each photosensitive module mounting slot in each matching photosensitive module mounting frame unit other than the reference photosensitive module mounting frame unit and the position information of the first positioning hole in each photosensitive module mounting slot in the target matching photosensitive module mounting frame unit, the target matching photosensitive module mounting frame unit arranged adjacent to the target matching photosensitive module mounting frame unit is determined.

[0035] The photosensitive module mounting frame unit includes N photosensitive module mounting slots arranged along a first direction, and each photosensitive module mounting slot includes two first positioning holes. Based on the position information of the first positioning hole in each photosensitive module mounting slot in each matched photosensitive module mounting frame unit and the position information of the first positioning hole in each photosensitive module mounting slot in the reference photosensitive module mounting frame unit, the matching score of each matched photosensitive module mounting frame unit is calculated sequentially, including: based on the position information of the first positioning hole in each photosensitive module mounting slot in each matched photosensitive module mounting frame unit and the position information of the first positioning hole in each photosensitive module mounting slot in the reference photosensitive module mounting frame unit, the sub-matching score of each photosensitive module mounting slot in each matched photosensitive module mounting frame unit is calculated sequentially; based on the sub-matching score of each photosensitive module mounting slot in each matched photosensitive module mounting frame unit, the matching score of each matched photosensitive module mounting frame unit is determined.

[0036] Based on the matching scores of each matching photosensitive module mounting frame unit, the target matching photosensitive module mounting frame unit to be arranged adjacent to the reference photosensitive module mounting frame unit is determined, including: based on the matching scores of each matching photosensitive module mounting frame unit, the matching photosensitive module mounting frame unit with the highest matching score is selected as the target matching photosensitive module mounting frame unit to be arranged adjacent to the reference photosensitive module mounting frame unit.

[0037] For a specific example, the position information of the first positioning holes in the first photosensitive module mounting slot arranged along the first direction of the reference photosensitive module mounting frame unit are (x11, y11) and (x12, y12), respectively; the position information of the first positioning holes in the second photosensitive module mounting slot arranged along the first direction are (x21, y21) and (x22, y22), respectively; the position information of the first positioning holes in the third photosensitive module mounting slot arranged along the first direction are (x31, y31) and (x32, y32), respectively; and the Nth photosensitive module arranged along the first direction... The position information of the first positioning holes in the mounting slots are (xN1, yN1) and (xN2, yN2), respectively. First, based on the relationship between the position information of the first positioning holes in the first photosensitive module mounting slot of the reference photosensitive module mounting frame unit arranged along the first direction and the preset position information, the error information of the first photosensitive module mounting slot of the reference photosensitive module mounting frame unit arranged along the first direction is determined. Then, the error information of the second photosensitive module mounting slot of the reference photosensitive module mounting frame unit arranged along the first direction is calculated sequentially, ..., the error information of the reference photosensitive module mounting frame unit along the first direction is calculated sequentially. The error information of the Nth photosensitive module mounting slot arranged in the first direction is used. Then, based on the relationship between the position information of the first positioning hole in each photosensitive module mounting slot arranged along the first direction of the first matching photosensitive module mounting frame unit and the preset position information, the error information of the first photosensitive module mounting slot arranged along the first direction of the first matching photosensitive module mounting frame unit is calculated sequentially. The error information of the second photosensitive module mounting slot arranged along the first direction of the first matching photosensitive module mounting frame unit is then calculated, and so on. The error information of the module mounting slot, and based on the relationship between the position information of the first positioning hole in each photosensitive module mounting slot arranged along the first direction of the Mth matching photosensitive module mounting frame unit and the preset position information, the error information of the first photosensitive module mounting slot arranged along the first direction of the Mth matching photosensitive module mounting frame unit, the error information of the second photosensitive module mounting slot arranged along the first direction of the Mth matching photosensitive module mounting frame unit, ..., the error information of the Nth photosensitive module mounting slot arranged along the first direction of the Mth matching photosensitive module mounting frame unit.

[0038] After determining the error information of the N photosensitive module mounting slots arranged along the first direction of the reference photosensitive module mounting frame unit and the error information of the N photosensitive module mounting slots arranged along the first direction of each matching photosensitive module mounting frame unit, the matching scores between the reference photosensitive module mounting frame unit and each matching photosensitive module mounting frame unit are calculated sequentially. The matching photosensitive module mounting frame unit with the highest matching score is selected as the target matching photosensitive module mounting frame unit arranged adjacent to the reference photosensitive module mounting frame unit. This process is repeated, using the target matching photosensitive module mounting frame unit arranged adjacent to the reference photosensitive module mounting frame unit as the reference photosensitive module mounting frame unit. The matching scores are then calculated with the remaining matching photosensitive module mounting frame units, and the target matching photosensitive module mounting frame unit adjacent to the target matching photosensitive module mounting frame unit is determined again, until the arrangement of M-1 matching photosensitive module mounting frame units is completed.

[0039] The specific process for calculating the matching scores between the reference photosensitive module mounting frame unit and each matching photosensitive module mounting frame unit after determining the error information of the N photosensitive module mounting slots arranged along the first direction of the reference photosensitive module mounting frame unit and the N photosensitive module mounting slots arranged along the first direction is as follows: First, based on the error information of the first photosensitive module mounting slot of the reference photosensitive module mounting frame unit and the first photosensitive module mounting slot of each matching photosensitive module mounting frame unit arranged along the first direction, the error information of the first photosensitive module mounting slot of each matching photosensitive module mounting frame unit arranged along the first direction is determined. Then, based on the error information of the second photosensitive module mounting slot of the reference photosensitive module mounting frame unit and the error information of the first photosensitive module mounting slot of each matching photosensitive module mounting frame unit arranged along the first direction, the error information of the first photosensitive module mounting slot of each matching photosensitive module mounting frame unit is determined. Based on the error information of the two photosensitive module mounting slots, the error information of the second photosensitive module mounting slot of each matching photosensitive module mounting frame unit arranged along the first direction is determined, ... and based on the error information of the Nth photosensitive module mounting slot of the reference photosensitive module mounting frame unit arranged along the first direction and the error information of the Nth photosensitive module mounting slot of each matching photosensitive module mounting frame unit arranged along the first direction, the error information of the Nth photosensitive module mounting slot of each matching photosensitive module mounting frame unit arranged along the first direction is determined. Then, based on the error information of the N photosensitive module mounting slots of each matching photosensitive module mounting frame unit arranged along the first direction, the sub-matching score of each photosensitive module mounting slot in each matching photosensitive module mounting frame unit is determined. Finally, based on the sub-matching score of each photosensitive module mounting slot in each matching photosensitive module mounting frame unit, the matching score of each matching photosensitive module mounting frame unit is determined.

[0040] In a specific example, during the process of determining the error information of the first photosensitive module mounting slot of the first matching photosensitive module mounting frame unit arranged along the first direction, based on the error information of the first photosensitive module mounting slot of the reference photosensitive module mounting frame unit arranged along the first direction and the error information of the first photosensitive module mounting slot of the first matching photosensitive module mounting frame unit arranged along the first direction: the error information of the first photosensitive module mounting slot of the reference photosensitive module mounting frame unit arranged along the first direction is D1, with the direction being positive; the error information of the first matching photosensitive module mounting frame unit arranged along the first direction is... The error information of the first photosensitive module mounting slot arranged in the first direction is D2, and the direction is negative. Then, the error information of the first photosensitive module mounting slot arranged in the first matching photosensitive module mounting frame unit along the first direction is |D1-D2|. Then, based on the error range of this error information and the arrangement position of the photosensitive module mounting slot corresponding to this error information, the sub-matching score of the first photosensitive module mounting slot in the matching photosensitive module mounting frame unit is determined. Similarly, the sub-matching score of each photosensitive module mounting slot in the matching photosensitive module mounting frame unit is determined.

[0041] It should be noted that the mounting slots for the photosensitive modules at different locations correspond to different matching weight values.

[0042] After determining the matching score of each matching photosensitive module mounting frame unit, the matching photosensitive module mounting frame unit with the largest matching score is selected as the target matching photosensitive module mounting frame unit to be arranged adjacent to the reference photosensitive module mounting frame unit. Then, the target matching photosensitive module mounting frame unit arranged adjacent to the reference photosensitive module mounting frame unit is used as the reference photosensitive module mounting frame unit. The matching score of the remaining matching photosensitive module mounting frame units is calculated in the above manner, and the target matching photosensitive module mounting frame units adjacent to the target matching photosensitive module mounting frame units are determined again, until the arrangement of M-1 matching photosensitive module mounting frame units is completed. After the arrangement of M-1 matching photosensitive module mounting frame units is completed, the arranged reference photosensitive module mounting frame units and matching photosensitive module mounting frame units form the target photosensitive module mounting frame.

[0043] It should be noted that, in the above embodiments, the specific process of determining the error information of the N photosensitive module mounting slots arranged along the first direction in the photosensitive module mounting frame unit is as follows: First, based on the position information of the first positioning hole in each photosensitive module mounting slot in the photosensitive module mounting frame unit, the center position information of each photosensitive module mounting slot in the photosensitive module mounting frame unit can be determined. Based on the relationship between the center position information of each photosensitive module mounting slot in the photosensitive module mounting frame unit and the preset position information, the error information of each photosensitive module mounting slot in the photosensitive module mounting frame unit is determined. The positive and negative values ​​in the error information reflect the error direction, and the deviation value in the error information reflects the error magnitude.

[0044] S140. Starting from the central photosensitive module mounting slot of the target photosensitive module mounting frame, determine the photosensitive module mounting pieces that match each photosensitive module mounting slot in sequence according to the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece.

[0045] After determining the target photosensitive module mounting frame, each photosensitive module mounting piece is matched with the target photosensitive module mounting frame to determine the photosensitive module mounting piece that matches each photosensitive module mounting slot in the target photosensitive module mounting frame.

[0046] In the specific implementation, starting from the central photosensitive module mounting slot of the target photosensitive module mounting frame, the photosensitive module mounting pieces matching each photosensitive module mounting slot are determined sequentially based on the position information of the first positioning holes in each photosensitive module mounting slot and the position information of the second positioning holes in each photosensitive module mounting piece. This includes: determining the central photosensitive module mounting slot of the target photosensitive module mounting frame based on the arrangement of each photosensitive module mounting frame unit in the target photosensitive module mounting frame and the number of photosensitive module mounting slots included in each photosensitive module mounting frame unit; and determining the central photosensitive module mounting slot based on the arrangement of each photosensitive module mounting frame unit in the target photosensitive module mounting frame and the number of photosensitive module mounting slots included in each photosensitive module mounting frame unit. Based on the position information of the first positioning hole in the mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece, the photosensitive module mounting piece that matches the central photosensitive module mounting slot is determined. Taking the central photosensitive module mounting slot as the center, each ring of photosensitive module mounting slots adjacent to the central photosensitive module mounting slot is determined sequentially, and based on the position information of the first positioning hole in each ring of photosensitive module mounting slots adjacent to the central photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece, the photosensitive module mounting piece that matches each ring of photosensitive module mounting slots adjacent to the central photosensitive module mounting slot is determined.

[0047] Specifically, determining the photosensitive module mounting piece that matches the central photosensitive module mounting slot based on the position information of the first positioning hole in the central photosensitive module mounting slot and the position information of the second positioning holes in each photosensitive module mounting piece includes: determining the first error information of the central photosensitive module mounting slot based on the relationship between the position information of the first positioning hole in the central photosensitive module mounting slot and preset position information; determining the second error information of each photosensitive module mounting piece based on the relationship between the position information of the second positioning hole in each photosensitive module mounting piece and preset position information; and determining the photosensitive module mounting piece that matches the central photosensitive module mounting slot based on the relationship between the first error information of the central photosensitive module mounting slot and the second error information of each photosensitive module mounting piece.

[0048] For example, if the photosensitive module mounting frame includes M photosensitive module mounting frame units, and each photosensitive module mounting frame unit includes N photosensitive module mounting slots, the central photosensitive module mounting slot of the target photosensitive module mounting frame is the N / 2th photosensitive module mounting slot of the M / 2th photosensitive module mounting frame unit. In this case, the N / 2th photosensitive module mounting slot of the M / 2th photosensitive module mounting frame unit is the central photosensitive module mounting slot. At this time, the first error information of the central photosensitive module mounting slot is determined according to the relationship between the position information of the first positioning hole in the central photosensitive module mounting slot and the preset position information. The second error information of each photosensitive module mounting piece is determined according to the relationship between the position information of the second positioning hole in each photosensitive module mounting piece and the preset position information. Then, the photosensitive module mounting piece corresponding to the second error information with the smallest sum of the first error information of the central photosensitive module mounting slot is selected as the photosensitive module mounting piece that matches the central photosensitive module mounting slot.

[0049] After determining the central photosensitive module mounting slot, taking the central photosensitive module mounting slot as the center, firstly, the position information of the first positioning hole in the first ring of photosensitive module mounting slots adjacent to the central photosensitive module mounting slot is obtained. Then, based on the relationship between the position information of the first positioning hole in the first ring of photosensitive module mounting slots adjacent to the central photosensitive module mounting slot and the preset position information, the first error information of the first ring of photosensitive module mounting slots adjacent to the central photosensitive module mounting slot, and the second error information of each remaining photosensitive module mounting piece are determined. The mounting pieces are then selected from the central photosensitive module mounting slot... The photosensitive module mounting piece that matches the first adjacent photosensitive module mounting slot is determined sequentially, with the central photosensitive module mounting slot as the center. This ensures the fitting accuracy between the photosensitive module mounting piece and the target photosensitive module mounting frame. Furthermore, during the fitting process, the closer the photosensitive module mounting piece is to the central photosensitive module mounting slot, the smaller the error between the photosensitive module mounting piece and the photosensitive module mounting slot, thus improving the fitting efficiency.

[0050] Similarly, in the above embodiments, the specific process of determining the first error information of the central photosensitive module mounting slot and the second error information of each photosensitive module mounting piece is as follows: First, based on the position information of the first positioning hole in the central photosensitive module mounting slot, the center position information of the central photosensitive module mounting slot can be determined. Based on the position information of the second positioning hole in each photosensitive module mounting piece, the center position information of each photosensitive module mounting piece can be determined. Then, based on the relationship between the center position information of the central photosensitive module mounting slot and the preset position information, the first error information of the central photosensitive module mounting slot is determined. Based on the relationship between the center position information of each photosensitive module mounting piece and the preset position information, the second error information of each photosensitive module mounting piece is determined. The positive and negative values ​​in the first and second error information reflect the error direction, and the error value in the error information reflects the magnitude of the deviation.

[0051] The CT detector assembly method provided in this embodiment first obtains the position information of the first positioning holes in each photosensitive module mounting slot and the position information of the second positioning holes in each photosensitive module mounting piece in the photosensitive module mounting frame unit; then, it selects one photosensitive module mounting frame unit as the reference photosensitive module mounting frame unit and selects other photosensitive module mounting frame units as matching photosensitive module mounting frame units; and based on the position information of the first positioning holes in each photosensitive module mounting slot in each matching photosensitive module mounting frame unit and the position information of the first positioning holes in each photosensitive module mounting slot in the reference photosensitive module mounting frame unit, it determines the arrangement of each matching photosensitive module mounting frame unit relative to the reference photosensitive module mounting frame unit. The process involves generating a target photosensitive module mounting frame. Finally, starting from the central photosensitive module mounting slot of the target photosensitive module mounting frame, and based on the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece, the photosensitive module mounting pieces that match each photosensitive module mounting slot are determined sequentially. This achieves optimal matching between the photosensitive module mounting frame and the photosensitive module mounting pieces. On the one hand, this ensures the fitting accuracy between the photosensitive module mounting pieces and the target photosensitive module mounting frame; on the other hand, during the fitting process, the closer the photosensitive module mounting pieces are to the central photosensitive module mounting slot, the smaller the error between the photosensitive module mounting pieces and the photosensitive module mounting slot, thus improving fitting efficiency.

[0052] As a preferred implementation method, first distance information between each mark and preset position information of each photosensitive module mounting piece and the mark and preset position information of each photosensitive module mounting slot in the target photosensitive module mounting frame are obtained; based on the first distance information between each mark and preset position information of each photosensitive module mounting piece and the mark and preset position information of each photosensitive module mounting piece, first angle error information of each photosensitive module mounting piece is determined; and based on the second distance information between each mark and preset position information of each photosensitive module mounting slot in the target photosensitive module mounting frame, second angle error information of each photosensitive module mounting slot is determined. At this point, starting from the central photosensitive module mounting slot of the target photosensitive module mounting frame, based on the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece, the photosensitive module mounting pieces that match each photosensitive module mounting slot are determined sequentially, including: Starting from the central photosensitive module mounting slot of the target photosensitive module mounting frame, the photosensitive module mounting pieces that match each photosensitive module mounting slot are determined sequentially based on the position information of the first positioning hole in each photosensitive module mounting slot, the position information of the second positioning hole in each photosensitive module mounting piece, the first angle error information of each photosensitive module mounting piece, and the second angle error information of each photosensitive module mounting slot.

[0053] In this implementation, by obtaining the distance information between the four markers in the photosensitive module mounting piece and the photosensitive module mounting slot and the preset position information, the first angle error information of each photosensitive module mounting piece and the second angle error information of each photosensitive module mounting slot are determined. Then, based on the position information of the first positioning hole in each photosensitive module mounting slot, the position information of the second positioning hole in each photosensitive module mounting piece, the first angle error information of each photosensitive module mounting piece, and the second angle error information of each photosensitive module mounting slot, the photosensitive module mounting piece that matches each photosensitive module mounting slot is determined sequentially.

Figure 3 As shown, the CT detector assembly includes: The position information acquisition module 310 is used to acquire the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece in the photosensitive module mounting frame unit. The reference photosensitive module mounting frame unit determination module 320 is used to select one photosensitive module mounting frame unit as the reference photosensitive module mounting frame unit and select other photosensitive module mounting frame units as matching photosensitive module mounting frame units. The target photosensitive module mounting frame determination module 330 is used to determine the arrangement of each matching photosensitive module mounting frame unit relative to the reference photosensitive module mounting frame unit based on the position information of the first positioning hole in each photosensitive module mounting slot in each matching photosensitive module mounting frame unit and the position information of the first positioning hole in each photosensitive module mounting slot in the reference photosensitive module mounting frame unit, and to generate the target photosensitive module mounting frame. The photosensitive module mounting plate matching module 340 is used to determine the photosensitive module mounting plates that match each photosensitive module mounting slot, starting from the central photosensitive module mounting slot of the target photosensitive module mounting frame, based on the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting plate.

[0055] The CT detector assembly apparatus provided in this embodiment first acquires the position information of the first positioning holes in each photosensitive module mounting slot and the position information of the second positioning holes in each photosensitive module mounting piece in the photosensitive module mounting frame unit; then, it selects one photosensitive module mounting frame unit as a reference photosensitive module mounting frame unit and selects other photosensitive module mounting frame units as matching photosensitive module mounting frame units; and, based on the position information of the first positioning holes in each photosensitive module mounting slot in each matching photosensitive module mounting frame unit and the position information of the first positioning holes in each photosensitive module mounting slot in the reference photosensitive module mounting frame unit, it determines the arrangement of each matching photosensitive module mounting frame unit relative to the reference photosensitive module mounting frame unit. The process involves generating a target photosensitive module mounting frame. Finally, starting from the central photosensitive module mounting slot of the target photosensitive module mounting frame, and based on the position information of the first positioning hole in each photosensitive module mounting slot and the position information of the second positioning hole in each photosensitive module mounting piece, the photosensitive module mounting pieces that match each photosensitive module mounting slot are determined sequentially.
