The air cooling can sufficiently and uniformly cool the plurality of detector units in the same detector module, and the cooling effect of the plurality of detector units in the axial direction is uniform, thereby avoiding the situation that the detection effect is reduced due to different cooling effects of the plurality of detector units in the axial direction. The required number of detectors for the ECT imaging device are connected in sequence along the axial direction for stepless expansion.

Description

Technical Field

[0001] This application relates to the field of medical imaging equipment technology, and in particular to ECT imaging equipment and its detectors. Background Technology

[0002] Positron emission tomography (PET) systems are playing an increasingly important role in the field of medical imaging. Current imaging techniques primarily use ordinary single-ring detectors, but their field of view is narrow.

[0003] Compared to ordinary single-ring detectors, ECT imaging equipment offers expanded field of view and improved efficiency. Through multi-ring layered design, it can cover a wider detection range. The synchronous operation of multiple detectors in the ECT imaging equipment enables multi-angle signal reception and processing, reducing scanning time and improving dynamic monitoring capabilities. The ECT imaging equipment features optimized field of view resolution and sensitivity, reducing image artifacts. The multi-ring redundancy design can compensate for noise or local failures, improving system robustness and signal-to-noise ratio.

[0004] Related ECT imaging devices include multiple detectors arranged sequentially along the axial direction, each detector comprising multiple detector modules arranged sequentially along the circumferential direction. Each detector module comprises multiple detector units arranged along the axial direction.

[0005] Most existing technologies employ air cooling to dissipate heat from the detectors. Air cooling solutions for ECT imaging equipment primarily involve setting up air inlet and outlet structures along the axis of each detector used in the ECT imaging device. As the cooling airflow sequentially distributes along the axial direction among multiple detector units, the cooling effect gradually diminishes, leading to uneven cooling among multiple detector units within a single detector module. This, in turn, reduces the overall cooling efficiency of the detectors used in the ECT imaging device, and consequently, reduces the cooling efficiency of the entire ECT imaging device composed of multiple detectors. Utility Model Content

[0006] Therefore, it is necessary to address the problem that in existing ECT imaging equipment, the cooling effect gradually decreases when multiple detector units are arranged axially along the cooling airflow, resulting in uneven cooling of multiple detector units in a single detector module. This leads to a decrease in the cooling effect of the detectors used in the ECT imaging equipment, and consequently, a decrease in the cooling effect of the ECT imaging equipment composed of multiple detectors used in the ECT imaging equipment. Therefore, it is necessary to provide an ECT imaging equipment and its detector.

[0007] A detector module for an ECT imaging device includes: a support and multiple detector modules, wherein the multiple detector modules are disposed on the support, and each detector module includes: a connecting shell, a connecting piece, and multiple detector units;

[0008] The connecting shell is connected to the inner wall of the bracket. An air inlet and an air outlet are provided on the side of the connecting shell near the inner wall of the bracket. The air inlet and the air outlet are arranged at intervals along the circumference of the bracket.

[0009] The connecting piece is connected to the side of the connecting shell near the air inlet. The connecting piece has multiple connecting structures, which are arranged at uniform intervals along a first direction, which is the axial direction of the bracket.

[0010] Each of the detector units corresponds to and is connected to one of the connection structures.

[0011] During installation and use, the detectors used in the aforementioned ECT imaging equipment require multiple detector units to be connected to multiple connecting structures one by one. After connection, the multiple detector units are arranged at intervals along the axial direction of the bracket. Since the multiple connecting structures are arranged at uniform intervals along the first direction, the spacing between adjacent detectors can be controlled to be the same. Then, the connecting piece is connected to the connecting shell, the connecting shell is connected to the air cavity shell, and the air cavity shell is connected to the bracket, thus forming a single ring detector for the ECT imaging equipment. At the same time, the air inlet and outlet are arranged at intervals along the circumference of the bracket. Therefore, the cooling air enters the connecting shell through the air inlet from the air outlet of the air cavity shell of one of the detector modules and cools the detector unit connected by the connecting piece and the connecting shell. The cooled air is discharged from the air outlet of the detector module and enters the corresponding air outlet, and then enters the air inlet of the next detector module, so that the cooling air forms a ring flow to cool the detector unit. Each air cavity shell can generate cooling air, thereby improving the cooling effect of multiple detectors in each detector module and preventing the air cooling effect from weakening along the circumference of the bracket. Furthermore, multiple detector units in the same detector module are arranged sequentially and evenly along the axial direction of the bracket, which allows the air cooling to provide sufficient and uniform cooling to the multiple detector units in the same detector module. This prevents the detection effect from being reduced due to different cooling effects of multiple detector units along the axial direction. In addition, the required number of detectors for ECT imaging equipment can be connected sequentially along the axial direction for stepless expansion, and the cooling effect of the expanded multi-ring detector is relatively stable.

[0012] In one embodiment, the connection structure includes a plurality of through holes and a plurality of connectors that correspond one-to-one;

[0013] The connector passes through the corresponding through hole and is connected to the detector unit.

[0014] In one embodiment, the plurality of the through holes are arranged at circumferential intervals along the detector unit.

[0015] In one embodiment, the connection structure includes a snap-fit ​​protrusion;

[0016] The detector unit has a snap-fit ​​groove on the side near the connecting shell, and the snap-fit ​​protrusion snaps into the inner wall of the snap-fit ​​groove.

[0017] The plurality of said snap-fit ​​protrusions extend along the second direction, and the first direction, the second direction and the radial direction of the bracket corresponding to the detector unit are perpendicular to each other.

[0018] In one embodiment, the detector module further includes a first connection component, the first connection component including a first connection portion and a first fastener;

[0019] The first connecting part is connected to the connecting shell, and the first connecting part is provided with a first connecting hole along the first direction. The bracket is provided with a plurality of second connecting holes along the first direction, and the plurality of second connecting holes are evenly spaced along the circumference of the bracket.

[0020] The first fastener passes through the first connecting hole and the corresponding second connecting hole.

[0021] In one embodiment, the detector for the ECT imaging device further includes multiple air cavity shells;

[0022] Multiple air cavity shells are evenly spaced along the circumference of the support and connected to the support. Each of the multiple air cavity shells corresponds to and is connected to a multiple detector module.

[0023] The air chamber shell has an air inlet chamber and an air outlet chamber that are connected to each other. The air inlet chamber is connected to the air inlet hole, and the air outlet chamber is connected to the air outlet hole.

[0024] In one embodiment, the support is ring-shaped, and a plurality of the detector modules are evenly arranged around the circumference of the support.

[0025] Another embodiment of this application provides an ECT imaging device, including a plurality of detectors and a support for the ECT imaging device, wherein the plurality of detectors for the ECT imaging device are spaced apart along an axial direction, and the detectors for the ECT imaging device include:

[0026] Multiple detector modules are supported and mounted on the bracket, and each detector module includes a connecting shell, a connecting piece, and multiple detector units;

[0027] The connecting shell is connected to the inner wall of the bracket. An air inlet and an air outlet are provided on the side of the connecting shell near the inner wall of the bracket. The air inlet and the air outlet are arranged at intervals along the circumference of the bracket.

[0028] The connecting piece is connected to the side of the connecting shell near the air inlet. The connecting piece has multiple connecting structures, which are arranged at uniform intervals along a first direction, which is the axial direction of the bracket.

[0029] Each of the detector units corresponds to and is connected to one of the connection structures.

[0030] In one embodiment, the ECT imaging device includes a plurality of the brackets. The ECT imaging device also includes a second connecting component, wherein a second connecting component is disposed between any two adjacent detectors of the ECT imaging device. The second connecting component includes a second connecting portion and two sets of second fasteners.

[0031] The second connecting part has two sets of third connecting holes, and the two sides of the annular bracket have two sets of fourth connecting holes respectively. The two sets of second fasteners, the two sets of third connecting holes and the two sets of fourth connecting holes of the two adjacent annular brackets are in one-to-one correspondence. The second fasteners are inserted through the corresponding third connecting holes and fourth connecting holes.

[0032] During the installation and use of the aforementioned ECT imaging equipment, multiple detector units need to be connected one-to-one with multiple connecting structures. After connection, the multiple detector units are arranged at intervals along the axial direction of the bracket. Since the multiple connecting structures are arranged at uniform intervals along the first direction, the spacing between adjacent detectors can be controlled to be the same. Then, the connecting piece is connected to the connecting shell, the connecting shell is connected to the air cavity shell, and the air cavity shell is connected to the bracket, thus forming a single ring for the detector of the ECT imaging equipment. At the same time, the air inlet and outlet are arranged at intervals along the circumference of the bracket. Therefore, the cooling air enters the connecting shell through the air inlet from the air outlet of the air cavity shell of one of the detector modules and cools the detector unit connected by the connecting piece and the connecting shell. The cooled air is discharged from the air outlet of the detector module and enters the corresponding air outlet, and then enters the air inlet of the next detector module, so that the cooling air forms a ring flow to cool the detector unit. Each air cavity shell can generate cooling air, thereby improving the cooling effect of multiple detectors in each detector module and preventing the cooling effect from weakening along the circumference of the bracket. Adjacent detector modules are connected via a second connecting part and two second fasteners. The distance between the two third connecting holes of the second connecting part is ensured to be the same, thus ensuring uniform gaps between multiple detector modules. Multiple detector units within the same detector module are arranged sequentially and evenly along the axial direction of the bracket. This allows for thorough and uniform cooling of the multiple detector units within the same module by air cooling. The even spacing along the axial direction of the multiple detector modules prevents uneven cooling that could reduce detection performance. Multiple detectors for the ECT imaging device are coaxially arranged and spaced apart, forming the ECT imaging device. Starting from a certain circumferential position, simultaneous air cooling of multiple detectors ensures synchronized cooling, guaranteeing stable and uniform cooling of the ECT imaging device. Adjacent detectors are connected via a second connecting component. The number of detectors required to form the ECT imaging device can be increased or decreased by disassembling the second connecting component. This allows for the seamless expansion of the ECT imaging device by sequentially connecting multiple detectors along the axial direction via the second connecting component.

[0033] In one embodiment, a first positioning groove and a second positioning groove are provided on both sides of the brackets along a first direction;

[0034] The first positioning groove of the bracket and the second positioning groove of the adjacent bracket form a positioning space, and the second connecting part is located in the corresponding positioning space.

[0035] The length of the second connecting part is equal to the sum of the length of the first positioning groove, the length of the second positioning groove, and the gap between two adjacent detector modules. Attached Figure Description

[0059] See Figure 1 The detector 20 for an ECT imaging device includes a support 21 and multiple detector modules 10. The detector modules 10 are mounted on the support 21 of the detector 20 for the ECT imaging device. The multiple detector modules 10 are connected to the inner wall of the support 21 to form the detector 20 for the ECT imaging device. (See also...) Figure 6 and Figure 7 The detector module 10 includes a connecting shell 100, a connecting piece 200, and multiple detector units 300. The connecting shell 100 is connected to the inner wall of the bracket 21. An air inlet 100a and an air outlet 100b are provided on the side of the connecting shell 100 near the inner wall of the bracket 21, and the air inlet 100a and air outlet 100b are arranged at intervals along the circumference of the bracket 21. The connecting piece 200 is connected to the side of the connecting shell 100 near the air inlet. The connecting piece 200 has multiple connecting structures 210, which are arranged sequentially and evenly at intervals along a first direction, which is the axial direction of the bracket 21. The multiple detector units 300 correspond one-to-one with and are connected to the multiple connecting structures 210, such as... Figure 5 .

[0060] During installation and use, the detector 20 for the ECT imaging device described above requires multiple detector units 300 to be connected one-to-one with multiple connecting structures 210. After connection, the multiple detector units 300 are arranged at intervals along the axial direction of the bracket 21. Since the multiple connecting structures 210 are arranged at uniform intervals along the first direction, the spacing between adjacent detectors can be controlled to be the same. Then, the connecting piece 200 is connected to the connecting shell 100, and the connecting shell 100 is connected to the bracket 21, thus forming a single-ring detector 20 for the ECT imaging device. At the same time, the air inlet 100a and the air outlet 100b are arranged at intervals along the circumference of the bracket 21. Therefore, cooling air enters the connecting shell 100 from the air inlet 100a of one of the detector modules 10 and is cooled by the connecting piece 200 and the connecting structure 210. The detector unit 300 connected to the housing 100 is cooled. The cooled air is discharged from the air outlet 100b of the detector module 10 and enters the air inlet 100a of the next detector module 10, so that the cooling air forms a ring flow to cool the detector unit 300. The multiple detector units 300 in the same detector module 10 are arranged evenly and sequentially along the axial direction of the bracket 21, so that the air cooling can fully and evenly cool the multiple detector units 300 in the same detector module 10, and will not cause the detection effect to be reduced due to different cooling effects of multiple detector units 300 in the axial direction. Furthermore, the required number of detectors 20 for ECT imaging equipment can be connected sequentially along the axial direction for stepless expansion, and the cooling effect of the expanded ECT imaging equipment 30 is relatively stable.

[0061] See Figure 6 and Figure 8 In one embodiment, the connection structure 210 includes a plurality of corresponding through holes 211 and a plurality of connectors. The connectors pass through the corresponding through holes 211 and are connected to the detector unit 300.

[0062] In this embodiment, the detector unit 300 is fixed to a specific position on the connecting piece 200 by means of a connecting hole and a corresponding detector unit 300, so as to position and connect the detector unit 300, thereby ensuring that the spacing between multiple adjacent detector units 300 in the same detector module 10 is equal.

[0063] See Figure 8 In one embodiment, a plurality of through holes 211 are arranged circumferentially and spaced apart along the bracket. Specifically, the detector unit 300 is a cuboid, and there are four through holes 211 and four connectors. The four through holes 211 correspond to the four corners of the detector unit 300 on the side near the connecting piece 200, thereby enabling the detector unit 300 to be stably connected to the connecting piece 200.

[0064] In one embodiment, the connection structure 210 includes a snap-fit ​​protrusion (not shown). The detector unit 300 has a snap-fit ​​groove (not shown) on the side near the connection housing 100, and the snap-fit ​​protrusion snaps into the inner wall of the snap-fit ​​groove.

[0065] In one embodiment, multiple snap-fit ​​protrusions extend along a second direction, and the first direction, the second direction, and the radial direction of the bracket 21 corresponding to the detector unit 300 are perpendicular to each other.

[0066] Specifically, the snap-fit ​​protrusion includes a protrusion (not shown) and two snap-fit ​​strips (not shown). Both the protrusion and the snap-fit ​​strips extend along the second direction. The snap-fit ​​strips are connected to the end of the protrusion away from the connecting piece 200. The two snap-fit ​​strips are located on both sides of the protrusion along the first direction, thus forming an inverted T-shaped structure. The snap-fit ​​groove is adapted to the snap-fit ​​protrusion, so that the detector unit 300 can be moved along the second direction to snap or unsnap the detector unit 300 to the connecting piece 200. Since multiple detector modules 10 are arranged in a single ring for the detector 20 of the ECT imaging device, the two adjacent detector modules 10 on both sides of the detector module 10 will limit the movement of the detector unit 300, thereby preventing the detector unit 300 from coming out of the connecting piece 200 after snapping, so that no connector is needed to connect the detector unit 300 to the connecting piece 200.

[0067] See Figure 8 In one embodiment, the connecting piece 200 has multiple positioning holes 200a corresponding to multiple detector units 300 along its thickness direction, and the multiple positioning holes 200a are arranged sequentially at intervals along a first direction. The detector unit 300 has a positioning protrusion that is adapted to the corresponding positioning hole 200a, so that the positioning protrusion can extend into the positioning hole 200a and abut against the connecting shell 100, thereby positioning the detector unit 300 and the connecting piece 200. At this time, it is convenient to pass the connector through the connecting hole and the corresponding detector unit 300, so as to facilitate the fixation of the detector unit 300 and the connecting piece 200.

[0068] See Figure 6 and Figure 7 In one embodiment, both the air inlet 100a and the air outlet 100b are strip-shaped holes extending along the first direction, so that cold air can enter from the strip-shaped air inlet 100a and cover multiple detector units 300. This ensures that the multiple detector units 300 arranged along the first direction can simultaneously contact the cold air at the same temperature for synchronous cooling, and prevents the multiple detector units 300 from cooling out of sync due to the diffusion of cold air along the first direction. This also avoids the situation where the detector unit 300 that comes into contact with the cold air first has a higher cooling effect than the detector unit 300 that comes into contact with the cold air later.

[0069] See Figure 2In one embodiment, the detector module 10 further includes a first connecting component 400, which includes a first connecting portion 410 and a first fastener 420. The first connecting portion 410 is connected to the connecting shell 100, and the first connecting portion 410 has a first connecting hole 410a along a first direction. The bracket 21 has a plurality of second connecting holes along the first direction, and the plurality of second connecting holes are evenly spaced along the circumference of the bracket 21. The first fastener 420 passes through the first connecting hole 410a and the corresponding second connecting hole.

[0070] In this embodiment, the detector module 10 is detachably connected to the bracket 21 by means of a first fastener 420 passing through the first connection hole 410a of the first connection portion 410 connected to the connection shell 100 and the second connection hole of the bracket 21.

[0071] See Figure 6 and Figure 7 In one embodiment, the detector module 10 further includes multiple sets of fins 500, which correspond one-to-one with multiple detector units 300. One end of the fin 500 is connected to the inner wall of the connecting shell 100 near the detector unit 300. By setting the fins 500, the contact area with the cold air is increased, thereby improving the cooling efficiency.

[0072] Specifically, the detector 20 for the ECT imaging device also includes multiple air cavity shells 22. These multiple air cavity shells 22 are arranged circumferentially around the support 21 and are evenly spaced, and connected to the support 21. Each air cavity shell 22 corresponds to and is connected to one of the multiple detector modules 10. Each air cavity shell 22 has a communicating air inlet cavity and an air outlet cavity. The air inlet cavity communicates with the air inlet hole 100a, and the air outlet cavity communicates with the air outlet hole 100b.

[0073] During installation and use, the detector 20 for the ECT imaging device described above requires multiple detector units 300 to be connected to multiple connecting structures 210 one by one. After connection, the multiple detector units 300 are arranged at intervals along the axial direction of the bracket 21. Since the multiple connecting structures 210 are arranged at uniform intervals along the first direction, the spacing between adjacent detectors can be controlled to be the same. Then, the connecting piece 200 is connected to the connecting shell 100, the connecting shell 100 is connected to the air cavity shell 22, and the air cavity shell 22 is connected to the bracket 21, thereby forming a single ring detector 20 for the ECT imaging device. At the same time, the air inlet 100a and the air outlet 100b are arranged at intervals along the circumference of the bracket 21. Therefore, the cooling air enters the connecting shell 100 through the air inlet 100a from the air outlet of the air cavity shell 22 of one of the detector modules 10 and cools the detector unit 300 connected to the connecting shell 100 through the connecting piece 200. Preferably, the air outlet of one of the air cavity shells 22 is connected to the air inlet of the adjacent air cavity shell 22. After being cooled, the air from one of the air chamber shells 22 exits through the air outlet 100b of the detector module 10 and enters the corresponding air outlet chamber, then enters the air inlet chamber of the next detector module 10. This creates a ring-shaped flow of cooling air to cool the detector unit 300. Each air chamber shell 22 generates cooling air, thereby improving the cooling effect of multiple detectors in each detector module 10 and preventing the cooling effect from weakening along the circumferential direction of the support 21. Furthermore, the multiple detector units 300 in the same detector module 10 are arranged evenly and sequentially along the axial direction of the support 21, ensuring that the air cooling can provide sufficient and uniform cooling to the multiple detector units 300 in the same detector module 10, preventing uneven cooling effects among the multiple detector units 300 along the axial direction that could lead to a decrease in detection performance.

[0074] In other embodiments, the air cavity shell 22 is located between the detector module 10 and the bracket 21. The detector module 10 and the bracket 21 are connected by the first connecting component 400, thereby clamping and fixing the air cavity shell 22 between the detector module 10 and the bracket 21.

[0075] Specifically, the bracket 21 is ring-shaped, and multiple detector modules 10 are evenly arranged around the circumference of the bracket 21, so that the air intake and exhaust around the circumference of the bracket 21 are more uniform.

[0076] Existing ECT imaging equipment typically uses multiple detector modules arranged in a ring for each detector module, with each module containing multiple spaced-apart detector units. However, the gaps between these detector units within each module are inconsistent. Axial air intake requires inlet and outlet structures along the axis of each detector. Since the gaps between the axially arranged detectors are also uneven, the cooling effect gradually diminishes as the cooling airflow sequentially passes through the axially arranged detector units and the detectors themselves. This results in uneven cooling of the detector units within a single module and across the entire ECT imaging equipment, ultimately impacting the overall cooling efficiency.

[0077] See Figure 1 , Figure 3 as well as Figure 4 This application also provides an ECT imaging device 30, which includes a plurality of detectors 20 and a support 21. The plurality of detectors 20 are spaced apart along the axial direction. Each detector 20 includes a plurality of detector modules 10 supported on the support 21. Each detector module 10 includes a connecting shell 100, a connecting piece 200, and a plurality of detector units 300. The connecting shell 100 is connected to the inner wall of the support 21. An air inlet 100a and an air outlet 100b are provided on the side of the connecting shell 100 near the inner wall of the support 21. The air inlet 100a and the air outlet 100b are arranged spaced apart along the circumference of the support 21. The connecting piece 200 is connected to the side of the connecting shell 100 near the air inlet 100a. The connecting piece 200 has a plurality of connecting structures 210, which are arranged sequentially and evenly spaced along a first direction, which is the axial direction of the support 21. And multiple detector units 300 are connected to multiple connection structures 210 in a one-to-one correspondence.

[0078] During installation and use, the aforementioned ECT imaging device 30 requires connecting multiple detector units 300 to multiple connecting structures 210 one by one. After connection, the multiple detector units 300 are arranged at intervals along the axial direction of the bracket 21. Since the multiple connecting structures 210 are arranged at uniform intervals along the first direction, the spacing between adjacent detectors can be controlled to be the same. Subsequently, the connecting piece 200 is connected to the connecting shell 100, and the connecting shell 100 is connected to the bracket 21, thus forming a single ring detector 20 for the ECT imaging device. At the same time, the air inlet 100a and the air outlet 100b are arranged at intervals along the circumference of the bracket 21. Therefore, cooling air enters the connecting shell 100 from the air inlet 100a of one of the detector modules 10 and cools the detector unit 300 connected to the connecting shell 100 via the connecting piece 200. The cooled air exits from the air outlet 100b of the detector module 10 and enters the air inlet 100a of the next detector module 10, thereby forming a ring flow of cooling air to cool the detector unit 300. The air cooling system employs a method where multiple detector units 300 within the same detector module 10 are arranged sequentially and evenly along the axial direction of the bracket 21. This ensures that the air cooling system can provide sufficient and uniform cooling to all detector units 300 within the same detector module 10, preventing uneven cooling effects that could reduce detection performance. Simultaneously, multiple detectors 20 for ECT imaging are coaxially arranged and spaced apart to form the ECT imaging device 30. Starting from a certain circumferential position, the multiple detectors 20 are simultaneously air-cooled, ensuring synchronized cooling and stable, uniform cooling of the ECT imaging device 30. Adjacent detectors 20 are connected by a second connecting component 31. The number of detectors 20 required to form the ECT imaging device 30 can be increased or decreased by disassembling the second connecting component 31. This allows for the seamless expansion of the ECT imaging device 30 by sequentially connecting multiple detectors 20 along the axial direction using the second connecting component 31.

[0079] Specifically, a single support may have one detector 20 for ECT imaging equipment, and multiple supports may be spaced apart along the axial direction, with multiple detectors 20 for ECT imaging equipment spaced apart along the axial direction. Alternatively, a single support may have multiple detectors 20 for ECT imaging equipment, with multiple detectors 20 for ECT imaging equipment spaced apart along the axial direction on a single support.

[0080] In one embodiment, the ECT imaging device includes multiple supports 21. The ECT imaging device also includes a second connecting assembly 31, with a second connecting assembly 31 disposed between any two adjacent detectors 20 of the ECT imaging device. The second connecting assembly 31 includes a second connecting portion 32 and two sets of second fasteners 33. The second connecting portion 32 has two sets of third connecting holes 34, and the supports 21 have two sets of fourth connecting holes 35. The two sets of second fasteners 33 and the two sets of third connecting holes 34 correspond one-to-one with the two sets of fourth connecting holes 35 of two adjacent detectors 20 of the ECT imaging device. The second fasteners 33 pass through the corresponding third connecting holes 34 and fourth connecting holes 35 to ensure that the spacing between the multiple detector modules 10 is equal. In this embodiment, one detector 20 of the ECT imaging device is disposed on one support, and multiple supports are spaced apart along the axial direction, as are multiple detectors 20 of the ECT imaging device.

[0081] During the installation and use of the aforementioned ECT imaging device 30, multiple detector units 300 need to be connected one-to-one with multiple connecting structures 210. After connection, the multiple detector units 300 are arranged at intervals along the axial direction of the bracket 21. Since the multiple connecting structures 210 are arranged at uniform intervals along the first direction, the spacing between adjacent detectors can be controlled to be the same. Subsequently, the connecting piece 200 is connected to the connecting shell 100, the connecting shell 100 is connected to the air cavity shell 22, and the air cavity shell 22 is connected to the bracket 21, thereby forming a single ring for the detector 20 of the ECT imaging device. At the same time, the air inlet 100a and the air outlet 100b are arranged circumferentially along the bracket 21. The detector modules are arranged in a staggered pattern, so cooling air enters the connecting shell 100 from the air outlet of the air chamber shell 22 of one of the detector modules 10 through the air inlet 100a, and cools the detector unit 300 connected to the connecting shell 100 via the connecting piece 200. The cooled air exits through the air outlet 100b of that detector module 10 and enters the corresponding air outlet chamber, and then enters the air inlet chamber of the next detector module 10. This creates a ring-shaped flow of cooling air to cool the detector unit 300. Each air chamber shell 22 can generate cooling air, thereby improving the cooling effect of multiple detectors in each detector module 10 and preventing the cooling effect from weakening circumferentially along the bracket 21. Adjacent detector modules 10 are connected by a second connecting part 32 and two second fasteners 33, and the distance between the two third connecting holes 34 of the second connecting part 32 is ensured to be the same, so that the gaps between multiple detector modules 10 are all the same. Multiple detector units 300 in the same detector module 10 are arranged sequentially and evenly at intervals along the axial direction of the bracket 21, so that air cooling can provide sufficient and uniform cooling to the multiple detector units 300 in the same detector module 10. The multiple detector modules 10 are also arranged sequentially and evenly at intervals along the axial direction of the bracket 21, so that the cooling effect of the multiple detector units 300 in the axial direction is different, which will not cause the detection effect to be reduced.

[0082] See Figure 1 , Figure 3 as well as Figure 4 In one embodiment, a first positioning groove 36 and a second positioning groove 37 are formed on both sides of the bracket 21 along a first direction. A fourth connecting hole 35 is formed on the bottom wall of both the first positioning groove 36 and the bottom wall of the second positioning groove 37. The first positioning groove 36 of the bracket 21 and the second positioning groove 37 of the adjacent bracket 21 form a positioning space 38. A second connecting portion 32 is partially located within the corresponding positioning space 38. Two second fasteners 33 are respectively inserted through the fourth connecting holes 35 of the first positioning groove 36 and the fourth connecting holes 35 of the second positioning groove 37. The length of the second connecting portion 32 is equal to the sum of the length of the first positioning groove 36, the length of the second positioning groove 37, and the gap between two adjacent detector modules 10.

[0083] In this embodiment, the second connecting part 32 is placed in the positioning space 38. The two ends of the second connecting part 32 along the axial direction of the bracket 21 abut against the side walls of the first positioning groove 36 and the second positioning groove 37, respectively, thereby pre-fixing the two adjacent detector modules 10. At this time, the fourth connecting hole 35 and the corresponding third connecting hole 34 are coaxially arranged, so as to facilitate the second fastener 33 to be inserted into the corresponding fourth connecting hole 35 and the corresponding third connecting hole 34. The length of the second connecting part 32 is equal to the sum of the length of the first positioning groove 36, the length of the second positioning groove 37 and the gap between the two adjacent detector modules 10. Therefore, when the specifications of multiple second connecting parts 32 are the same, the specifications of multiple first positioning grooves 36 are the same and the specifications of multiple second positioning grooves 37 are the same, after the second connecting part 32 connects the two detector modules 10 through the second fastener 33, the spacing of the multiple detector modules 10 is the same.

[0084] Preferably, the distance between two adjacent detector modules 10 is equal to the distance between two adjacent detector units 300 in the same detector module 10.

[0085] Preferably, the third connecting hole 34 has a first hole (not shown) and a second hole (not shown) connected to each other. The diameter of the first hole is larger than that of the second hole and forms a countersunk hole structure. The head of the second fastener 33 is located in the first hole, so that the use of the ECT imaging device 30 will not be affected by the protrusion of the second connecting part 32.
