Those skilled in the art may make reasonable configurations according to the different shapes of the photosensitive element 20, and this embodiment does not limit this.

[0046] The following is a further description with reference to the accompanying drawings.

[0047] Please refer to Figures 1 to 3 The utility model provides a detector module, including: a detector housing 30; a plurality of brackets 10, arranged side by side along the extension direction of the detector housing 30, and the brackets 10 are vertically plugged into the detector housing 30; each bracket 10 is provided with a photosensitive element 20; at least one bracket 10 is provided with a protrusion 101, the protrusion 101 protrudes outward along the direction close to the adjacent bracket 10, and the protrusion distance of the protrusion 101 relative to the bracket 10 is greater than the protrusion distance of the photosensitive element 20 relative to the bracket 10. It should be noted that the extension direction of the detector housing 30 is a first direction X (such as Figure 2 As shown), the protruding distance of the protruding portion 101 relative to the bracket 10 refers to the protruding distance of the protruding portion 101 relative to the bracket 10 in the first direction X. Correspondingly, the protruding distance of the photosensitive element 20 relative to the bracket 10 refers to the protruding distance of the protruding portion 101 relative to the bracket 10 in the first direction X. Please refer to Figure 1 The bracket 10 has a main body 102, one end of the main body 102 is connected to the detector housing 30 in a pluggable manner through a connecting mechanism. In an optional embodiment, a pin (not shown in the figure) is provided on the detector housing 30, and a pin hole (not shown in the figure) is opened at one end of the main body 102, and the connection is achieved by inserting the pin into the pin hole; in another optional embodiment, a groove (not shown in the figure) is provided on the detector housing 30, and a snap-fitting piece (not shown in the figure) matched with the groove is provided at one end of the main body 102, and the connection is achieved by inserting the snap-fitting piece into the groove; in some other embodiments, one end of the main body 102 and the detector housing 30 can also be connected in other ways, which is not limited in this embodiment. Please refer to Figures 2 to 3 In addition, the protrusion 101 may be a boss (see Figure 1 , Figure 6 as well as Figure 8 ), or a cylinder (see Figure 7), or components of other shapes, please refer to the following description for details. In the present embodiment, the photosensitive element 20 is arranged on the side of the bracket 10 close to the detector housing 30. It can be understood by those skilled in the art that the photosensitive element 20 needs to basically completely cover the ray incident direction of the bracket 10. After the installation of multiple detector modules, the photosensitive element 20 should form a nearly complete plane, and the gap between adjacent photosensitive elements 20 should be as small as possible. In this way, the detector module provided in the present embodiment is provided with a protrusion 101 on the bracket 10, and the protrusion distance of the protrusion 101 is greater than the protrusion distance of the photosensitive element 20, so that during the installation or disassembly of the bracket 10, the protrusion 101 can contact the adjacent bracket 10 before the photosensitive element 20, thereby avoiding the problem of damage to the photosensitive element 20 due to collision due to too small a spacing, and further extending the service life of the detector module.

[0048] Please refer to Figures 1 to 5 , a plurality of brackets 10 are arranged along the first direction X, and the protrusions 101 are arranged on the same side or different sides of the brackets 10 along the first direction X. It should be noted that, as a preferred embodiment, Figure 1 As shown, at least two protrusions 101 are provided on the bracket 10, and the two protrusions 101 are located at both ends of the photosensitive element 20 along the second direction Z. If only one end of the photosensitive element 20 along the second direction Z is provided, during the installation or removal of the bracket 10, once one end of the bracket 10 is fixed to the detector housing 30 and the other end is in a free state, the free end is likely to collide with the adjacent detector module after being rotated by force during installation. In this configuration, by providing protrusions 101 at both ends of the photosensitive element 20 along the second direction Z, it is possible to completely avoid the collision of the photosensitive element 20 during the installation or removal of the bracket 10, thereby further extending the service life of the detector module. In this embodiment, a plurality of detector modules are arranged in a fan shape on the detector housing 30, that is, the first direction X is not a straight line direction, but along Figures 2 to 3 The arc direction setting shown in Figure 1 as well as Figures 4 to 8 In the figure, for the convenience of marking, the arrangement direction of the detector modules (ie, the first direction X) is marked as a straight line, but in actual application, it should be understood as follows Figures 2 to 3 As shown in the arc, since the distance between two adjacent detector modules is relatively close, the arrangement direction between the two can be approximately a straight line.

[0049] Based on this, this embodiment provides two configuration schemes for the protrusion 101 .

[0050] The first option: Please refer to Figure 4, the protrusions 101 are arranged on the same side of the bracket 10 along the first direction X, and are arranged at intervals along the second direction Z. The two protrusions 101 are arranged on the same side of the bracket 10, and are respectively arranged at the two ends of the photosensitive element 20 along the second direction Z. During the installation of the bracket 10, even if the bracket 10 rotates, the protrusions 101 can contact the adjacent detector module before the photosensitive element 20, and can effectively protect the photosensitive element 20 from damage. It should be noted that at this time, the spacing between the two protrusions 101 should be greater than the length of the photosensitive element 20 along the second direction Z, and the spacing between the two protrusions 101 is the minimum distance between the side walls of the two protrusions 101. If the spacing between the two protrusions 101 is equal to or less than the length of the photosensitive element 20 along the second direction Z, the protrusions 101 will directly hit the photosensitive element 20 of the adjacent detector module during the installation of the bracket 10 due to the small spacing between the adjacent detector modules, thereby causing damage to the photosensitive element 20.

[0051] The second option: Please refer to Figure 5 , at least two protrusions 101 are arranged on the bracket 10, wherein at least one protrusion 101 is arranged on one side of the bracket 10 along the first direction X, at least one protrusion 101 is arranged on the other side of the bracket 10 along the first direction X, and the two protrusions 101 are arranged at intervals along the second direction Z. Taking two protrusions 101 as an example, one protrusion 101 is located on one side of the bracket 10 along the first direction X, and is located at one end of the photosensitive element 20 along the second direction Z; the other protrusion 101 is located on the other side of the bracket 10 along the first direction X, and is located at a position corresponding to the other end of the photosensitive element 20 along the second direction Z. It should be noted that at this time, the spacing between the two protrusions 101 should be greater than the length of the photosensitive element 20 along the second direction Z. At the same time, the position of the protrusion 101 on any detector module should remain consistent, that is, the relative positions of all photosensitive elements 20 and the protrusions 101 should correspond one to one. Otherwise, if the protrusions 101 of two adjacent detector modules are randomly arranged, it cannot be guaranteed that the photosensitive element 20 will not be bumped due to the rotation of the adjacent detector modules.

[0052] In an alternative example, see Figure 1 as well as Figure 6 to Figure 7 , the photosensitive element 20 has a length range 40 along the mounting direction Y of the bracket 10, and the protrusion 101 is at least located within the length range 40 along the mounting direction Y of the bracket 10. As described above, the photosensitive element 20 is a rectangular parallelepiped component, which has a certain length range 40 in the mounting direction Y of the bracket 10, and the protrusion 101 can be as follows Figure 1 The main body 102 of the bracket 10 is arranged along the installation direction Y of the bracket 10, and can also be arranged as shown. Figure 6 to Figure 7As shown, the protrusion 101 is only arranged within the length range 40 of the photosensitive element 20 along the installation direction Y of the bracket 10. Those skilled in the art can reasonably configure the protrusion 101 according to actual conditions, and this embodiment does not limit this.

[0053] As a preferred embodiment, the protrusions 101 on the same bracket 10 have the same protrusion distance. In this configuration, the protrusions 101 on the same detector module have the same protrusion distance, which can ensure that two adjacent detector modules remain relatively parallel during the process of contacting each other through the protrusions 101, thereby minimizing the probability of collision.

[0054] Please refer to Figure 8 and Fig. 9 The bracket 10 has a block body 103, the photosensitive element 20 is arranged on the block body 103, and the protrusion 101 is arranged on the side of the block body 103 and corresponds to the position of the photosensitive element 20 on the block body 103. Figure 1 as well as Figure 6 to Figure 7 In the detector module shown in FIG. 1 , the main body 102 of the bracket 10 is arranged in a long strip shape. Figure 8 In the detector module shown, the main body 102 of the bracket 10 is a block-shaped main body 103, whose length in the second direction Z is much smaller than Figure 1 as well as Figures 7 and 8 The main body 102 of the bracket 10 in the block body 10, the circuit board 50 and the photosensitive element 20 are respectively arranged on the top and bottom surfaces of the block body 103, and the detector modules are arranged in sequence along the direction perpendicular to the side of the block body 103. Therefore, the protrusion 101 only needs to be arranged on the side of the block body 103 corresponding to the position of the photosensitive element 20, and only on one side of the block body 103 to achieve the same effect; it should be noted that in Figure 8 In the illustrated example, the mounting direction Y of the bracket 10 is arranged along the thickness direction of the photosensitive element 20 (ie, the bracket 10 is pluggably connected to the detector housing 30 along the up and down direction); in other embodiments, the mounting direction Y of the bracket 10 may also be arranged along the thickness direction of the photosensitive element 20. Fig. 9 The bracket 10 is arranged along the long side direction of the block body 103. At this time, the installation direction Y is arranged parallel to the second direction Z, and the bracket 10 is pluggably connected to the detector housing 30 along the left and right direction.

[0055] Regarding the shape of the protrusion 101, this embodiment provides several different shapes, please refer to Figure 1 as well as Figures 6 to 9 .exist Figure 1 , Figure 6 , Figure 8 and Fig. 9In the embodiment, the protrusion 101 is in the shape of a cuboid, and the top and side surfaces of the protrusion 101 are both planes. In some other embodiments, the protrusion 101 may be in the shape of a prism with a plane top surface and an inclined side surface; the protrusion 101 may also be in the shape of a curved top surface and a plane side surface; the protrusion 101 may also be in the shape of a curved top surface and a curved side surface. Figure 7 In the embodiment, the protrusion 101 is cylindrical. In other embodiments, the protrusion 101 may also be a truncated cone with a round top and an inclined side. Figures 1 to 9 The shape of the protrusion 101 shown in the figure is for demonstration only and does not limit the shape of the protrusion 101. Those skilled in the art may reasonably configure the shape of the protrusion 101 according to actual conditions, and this embodiment does not limit this.

[0056] In another embodiment, please refer to Figures 2 to 3 The utility model also provides a CT detector assembly, including: a detector housing 30, having an arc-shaped extension surface 301; a plurality of brackets 10, arranged side by side along the extension direction of the detector housing 30, and each bracket 10 is vertically plugged into the arc-shaped extension surface 301; each bracket 10 is provided with a photosensitive element 20, and the photosensitive element 20 extends from the proximal end of the arc-shaped extension surface 301 to the distal end of the arc-shaped extension surface 301; a protrusion 101 is provided between at least two adjacent brackets 10, so that an escape space is formed between the two adjacent brackets 10, and the escape space can accommodate the photosensitive element 20. It should be noted that the photosensitive element 20 extends from the proximal end of the arc-shaped extension surface 301 to the distal end of the arc-shaped extension surface 301, which can be understood as a single photosensitive element 20 extending from one end of the arc-shaped extension surface 301 to the other end of the arc-shaped extension surface 301, and can also be understood as a plane formed by splicing multiple photosensitive elements 20 extending from one end of the arc-shaped extension surface 301 to the other end of the arc-shaped extension surface 301. By configuring in this way and using the above-mentioned detector module, the photosensitive element 20 is prevented from being damaged by collision during the installation or removal of the bracket 10, thereby extending the service life of the CT detector assembly. At the same time, the consumption of consumables during the use of the CT detector assembly is reduced, thereby further reducing the use cost of the CT detector assembly.

[0057] In summary, in the detector module and CT detector assembly provided in the embodiments of the utility model, the detector module includes: a detector shell; a plurality of brackets, which are arranged side by side along the extension direction of the detector shell, and the brackets are vertically inserted into the detector shell; each bracket is provided with a photosensitive element; at least one bracket is provided with a protrusion, the protrusion protrudes outward in a direction close to the adjacent bracket, and the protruding distance of the protrusion relative to the bracket is greater than the protruding distance of the photosensitive element relative to the bracket.

[0058] With such configuration, the detector module provided in the present application is provided with a protruding portion on the bracket, and the protruding distance of the protruding portion is greater than the protruding distance of the photosensitive element, so that during the installation or removal of the bracket, the protruding portion can contact the adjacent bracket before the photosensitive element, thereby avoiding the problem of damage to the photosensitive element caused by collision;

[0059] Furthermore, the CT detector assembly provided in the present application uses the above-mentioned detector module to avoid damage to the photosensitive element caused by collision during the installation or disassembly of the bracket, thereby extending the service life of the CT detector assembly, while also reducing the consumption of consumables during the use of the CT detector assembly, further reducing the use cost of the CT detector assembly.
