Technical Field

Background

In the related art, a photon-based computerized tomography (Computed Tomography, CT) apparatus, that is, a detector system is disposed in the CT apparatus, and the detector system is configured to receive radiation emitted by a radiation source in the CT apparatus and passing through a human body, and the detector system includes a plurality of detector modules arranged along an X-direction, the detector modules convert received optical signals into electrical signals, and the CT apparatus determines a scanning result according to the electrical signals.

In the disclosed implementation, the following problems exist with the positioning of the detector modules:

Each detector module is arranged on a section of circular arc concentric with the focus along the X-direction of the detector system, and each detector module is also positioned on a section of circular arc concentric with the focus along the Z-direction of the detector system, so as to ensure that the attenuation degree of rays emitted by the ray source into each detector module has consistency, thereby ensuring the scanning imaging effect. When the detector modules are assembled into a detector system, the mounting positions of the collimators in the detector modules need to be precisely adjusted so that the collimators in the detector modules are located concentrically with the focal point in both the X-direction and the Z-direction.

Furthermore, structural interference between collimators of a plurality of detector modules in the detector system should be avoided. Therefore, gaps inevitably exist between adjacent collimators, but in the process of splicing detector modules to form a detector system, if the gaps between the collimators are too large, the acquisition of electric signals of the whole detector system is affected, and the imaging quality of a scanned image is also affected.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the application and thus may include information that does not form the prior art that is already known to those of ordinary skill in the art.

As shown in fig. 1, the detector module provided in the embodiment of the present application is suitable for a detector system, which includes a plurality of detector modules arranged along a first direction (X-direction). The plurality of detector modules are arranged on a circular arc concentric with the focal spot such that the distance from each detector module to the focal spot is uniform to ensure uniform attenuation characteristics of the radiation source at the focal spot into the detector modules for subsequent image processing. The plurality of detector modules 10 are arranged in circular arcs concentric with the focal point in the X-direction and the Z-direction, the receiving surface of the collimator 100 in each detector module 10 being arranged on one spherical surface, i.e. a sphere-like surface as shown in fig. 1. A plurality of detector modules are assembled to a fixed support 300 and arc-shaped along both the X and Z directions to form a set of detector systems.

As shown in fig. 2 to 4, an embodiment of the present application provides a detector module 10, the detector module 10 including: the collimator 100, the holder 200, the bracket 300, and the first and second adjusters 400 and 500. The holder 200 includes a mounting portion 204 and a holding portion 203 connected to the mounting portion 204 and used for holding the collimator 100; the bracket 300 is used for carrying the collimator 100; the first adjusting member 400 is disposed on the mounting portion 204, and the first adjusting member 400 is used for adjusting the mounting positions of the clamping member 200 and the bracket 300; the second adjusting member 500 is disposed at the clamping portion 203, and the second adjusting member 500 is used for adjusting the clamping state between the clamping member 200 and the collimator 100.

Collimator 100 may be a grating collimator, also known as an anti-scatter grid, for confining and collimating radiation emitted by a radiation source. The grating collimator 100 is typically manufactured by tungsten metal 3D printing, and has a grid-shaped elongated shape inside. During a radiation scan, the radiation beam impinges on the scan object and the scattered radiation is received by the collimator 100 in the detector module 10. The collimator 100 ensures that the size and shape of the beam remains unchanged during the scanning process. Collimator 100 may also reduce scattered radiation, and only scattered radiation meeting certain requirements may pass through collimator 100 and be received by detector sub-module 600 of detector module 10, contributing to improved quality and accuracy of the scanned image.

The collimator 100 is constructed in a bar-like structure, and both ends of the collimator 100 in the Z direction are provided with holders 200. The number of the holders 200 is generally two, and the two holders 200 are respectively held at both ends of the collimator 100 in the Z-direction. The clamping portion 203 of the clamping member 200 can clamp the collimator 100, and then the clamping member 200 is disposed on the bracket 300, and the bracket 300 supports the collimator 100.

The holder 200 comprises a mounting portion 204 for forming a fixed mounting relationship with the bracket 300 and a holding portion 203 for holding the collimator 100 with the holder 203.

For example, as shown in fig. 6, the mounting portion 204 may be integrally formed with the clamping portion 203, that is, the clamping member 200 is integrally formed. The clamping member 200 may be designed as a non-conductive clamping member as a whole, i.e. the clamping member 200 is made entirely of non-conductive material.

The overall design of the clip 200 as a non-conductive clip can further ensure the insulating properties of the clip 200, thereby insulating the collimator 100 from working devices that may generate high voltages (e.g., the high voltage connector 800), further improving the safety performance of the collimator 100 and thus the detector module 10.

The clamp 200, which is made of a non-conductive material, has almost zero electrical conductivity, and can realize insulation between the collimator 100 and a working device (insulation between the collimator 100 and the working device, which may generate a high voltage, thereby ensuring the safety of the collimator 100 and the detector module 10 in use) even under the working condition of a strong electric field.

For example, as shown in fig. 7, the mounting portion 204 and the clamping portion 203 may be a separate structure. In the Y direction, the clamping portion 203 is located above the mounting portion 204 and is fixedly connected to the mounting portion 204. The mounting portion 204 may be a non-conductive mounting portion. The clamping portion 203 may be an insulating clamping portion 203 or a metal clamping portion.

The first adjusting member 400 may be disposed on the mounting portion 204, the clamping member 200 is disposed on the bracket 300 through the first adjusting member 400, and the first adjusting member 400 may adjust the mounting position of the clamping member 200 and the bracket 300. During assembly of a plurality of detector modules 10, the detector modules 10 should lie on a circular arc concentric with the focal point and gaps between adjacent detector modules 10 should be reduced as much as possible, and the purpose of actually adjusting the detector modules 10 is to adjust the distance of the collimator 100 relative to the focal point and the gaps between collimators 100 in adjacent detector modules 10. The first repositioning of the collimator 100 is achieved by adjusting the first adjustment member 400 such that the clamping member 200 is moved in the X-direction or the Z-direction to a desired target position relative to the support 300.

Alternatively, the first adjuster 400 may be a fastener. When the relative position of the clamping member 200 and the bracket 300 needs to be adjusted, the fastening relationship between the fastening member and the bracket 300 can be released, and the fastening member and the bracket 300 are fastened and matched after the clamping member 200 is moved. The fastener may be a screw.

Accordingly, the mounting portion 204 may be provided with a first mounting hole 207 accommodating the first adjuster 400, and the first adjuster 400 is fixed to the bracket 300 after passing through the first mounting hole 207.

Optionally, the first adjusting member may be a slidable locking member, and when the relative position between the clamping member and the bracket needs to be adjusted, the locking relationship between the locking member and the bracket may be released, and the locking member is locked to the bracket after the clamping member is moved.

The first adjuster 400 is detachably coupled with the bracket 300. When the mounting relationship between the first adjusting member 400 and the bracket 300 is released, the clamping member 200 and the collimator 100 can be detached from the bracket 300 for maintenance or replacement, thereby realizing the requirement of flexible detachment.

The second adjusting member 500 is disposed on the clamping portion 203, and the second adjusting member 500 can adjust the clamping state between the clamping portion 203 and the collimator 100. The clamping state may include a fixed clamping state and an adjustable state. In the case where the second adjuster 500 adjusts the clamping state between the clamping portion 203 and the collimator 100 from the adjustable state to the fixed clamping state, the second adjuster 500 may cause the clamping portion 203 to clamp the collimator 100 to fasten the collimator 100 at the target position. In the case that the second adjusting member 500 adjusts the clamping portion 203 and the collimator 100 from the fixed clamping state to the adjustable state, the collimator 100 may be moved in the Z direction or the X direction with respect to the clamping member 200 to move the collimator 100 to a suitable target position, thereby achieving a second repositioning of the collimator 100.

Alternatively, the second adjuster 500 may be a fastener. When it is necessary to adjust the relative position between the clamping portion 203 and the collimator 100, the second adjusting member 500 may be adjusted to adjust the clamping state between the clamping portion 203 and the collimator 100 to switch between the adjustable state and the clamping fixed state. The fastener may be a screw.

Accordingly, the clamping portion 203 is provided with a second mounting hole 208, and the second mounting hole 208 may be provided at the clamping portion 203 and the mounting portion 204. The second adjusting member 500 is movably disposed in the second mounting hole 208 to adjust the clamping state of the clamping member 200 and the collimator 100. The second regulating member 500 and the first regulating member 400 have a distance in the Z direction to prevent mutual interference when the first regulating member 400 and the second regulating member 500 need to be regulated.

It should be noted that, when the detector module 10 is assembled and the position of the collimator 100 needs to be adjusted, the first adjusting member 400 and/or the second adjusting member 500 may be adjusted according to the actual working conditions. For example: in the case where a position adjustment for a large displacement of the collimator 100 is required, the first adjuster 400 may be adjusted, and the position of the collimator 100 may be adjusted by adjusting the relative positions of the clip 200 and the bracket 300. In the case where the position of the collimator 100 needs to be adjusted with a small displacement, the second adjuster 500 may be adjusted to directly move the collimator 100 to the target position and then clamp the collimator 100 by the clamping portion 203. The first adjuster 400 and the second adjuster 500 may be adjusted to adjust the collimator 100 to the target position sequentially or simultaneously.

Thus, the detector module 10 according to the embodiment of the present application may adjust the collimator 100 to a suitable target position by adjusting the first adjusting member 400 and/or the second adjusting member 500. The positioning of the collimator 100 can be realized by the first adjusting piece 400, the clamping state of the collimator 100 can be adjusted by the second adjusting piece 500, and the first adjusting piece 400 and the second adjusting piece 500 can respectively and independently adjust the mounting position of the collimator 100, so that the mode of adjusting the collimator 100 can have various choices according to the actual working conditions.

Optionally, the bracket 300 is provided with a mating portion, and the first adjusting member 400 can move relative to the mating portion to adjust the relative position of the clamping member 200 and the bracket 300.

In this embodiment, the bracket 300 may be provided with a matching portion, and during the process of adjusting the collimator 100 to the target position by the clamping member 200, the clamping member 200 also drives the first adjusting member 400 to move relative to the matching portion. After the clamping member 200 is moved to a proper position, the first adjusting member 400 is adjusted to fix the clamping member 200 to the bracket 300, so that the collimator 100 can complete the position adjustment and positioning.

The fitting portion may be a plurality of fixing holes formed on the bracket 300, the plurality of fixing holes may be arranged along the X-direction or the Z-direction, and the first adjuster 400 may be a screw. The first adjuster 400 is fastened to cooperate with different fixing holes so that the holder 200 can be adjusted in the installation position with the bracket 300.

The mating portion may also be a first surface of the bracket 300 facing the clamping member 200, where the first surface is adapted to the surface of the clamping member 200 facing the bracket 300, so that the clamping member 200 drives the first adjusting member 400 to move relative to the mating portion. When the clamping member 200 moves to a proper position in the X-direction and/or the Z-direction on the first surface, the first adjusting member 400 is fastened to the bracket 300, so that the clamping member 200 can adjust the installation position with the bracket 300.

The matching part can also be a slideway which is arranged on the bracket and used for the first adjusting piece to slide, the slideway can be arranged along the X direction or the Z direction, and the first adjusting piece can be a locking piece which can slide. The clamping piece drives the first adjusting piece to slide so that the collimator is located at a target position, and then the first adjusting piece is adjusted to lock the clamping piece to the matching part, so that the installation positions of the clamping piece and the bracket are adjusted.

In this way, by providing the fitting portion on the bracket 300 that mates with the first adjusting member 400, after the clamping member 200 drives the collimator 100 to move to the target position, a fastening fit is formed between the first adjusting member 400 and the fitting portion, so that the mounting position of the clamping member 200 and the bracket 300 can be adjusted.

Optionally, the clamping portion 203 is provided with a deformation zone 205 and a clamping opening 206 communicating with the deformation zone 205, and the clamping opening 206 is used for accommodating the connecting falcon 102 of the collimator 100; the second adjusting member 500 is disposed through the clamping portion 203 and is capable of deforming the deformation section 205 to adjust the opening width of the clamping opening 206.

As shown in fig. 5, the collimator 100 is provided at both ends thereof with connecting tennons 102 extending in the Z-direction, and the connecting tennons 102 can be held by holding members 200. The connecting tongue 102 is disposed in the middle region of the collimator 100 along the Y-direction to ensure that the clamping member 200 stably clamps the collimator 100.

The clamping portion 203 is provided with a deformation section 205 and a clamping port 206 communicating with the deformation section 205. The above "disposing" may be understood that the deformation section 205 and the clamping opening 206 may be disposed in the clamping portion 203; it is also understood that the clamping portion 203 defines the deformation zone 205 and the shape of the clamping mouth 20.

Illustratively, as shown in fig. 6, a deformation zone 205 and a grip orifice 206 are disposed within the grip 203.

Illustratively, as shown in fig. 7, the deformation zone 205 and the grip orifice 206 may also be constructed from a grip 203, the grip 203 defining the location and shape of the deformation zone 205 and the grip orifice 206. For example: the clamping portion 203 defines a deformation zone 205 and at least one wall of a clamping mouth 206.

The clamping opening 206 is formed on a side of the clamping portion 203 facing the collimator 100. The location of the opening of the clamping opening 206 coincides with the Y-direction height of the attachment tongue 102 in the collimator 100. The length of clamping port 206 in the X-direction may be greater than the length of connecting tongue 102 in the X-direction, and the depth of clamping port 206 in the Z-direction may be greater than the length of connecting tongue 102 in the Z-direction. So that attachment tongue 102 can be moved in clamping opening 206 to adjust the position of collimator 100.

The clamping portion 203 is further provided with a deformation zone 205. The deformation zone 205 has a hollow structure. The deformation zone 205 communicates with the clamping opening 206. The second adjuster 500 may be disposed through the clamping portion 203 along the Y direction. The second adjusting member 500 is disposed through the clamping portion 203 and also disposed through the deformation region 205, and further extends in the Y direction toward the inside of the clamping member 200.

One end of the second adjusting member 500 is clamped in the clamping portion 203, and when the second adjusting member 500 continues to extend toward the inside of the clamping member 200 along the Y direction, the deformation section 205 is pressed and deformed by the second adjusting member 500. The two opposite wall surfaces of the deformation section 205 along the Y direction gradually approach, and the part of the clamping portion 203 opposite to the clamping opening 206 is bent, so that the opening width L1 of the clamping opening 206 along the Y direction gradually decreases, the connecting falcon 102 can be clamped by the clamping member 200, and the second adjusting member 500 is stably fixed in the clamping portion 203, so that continuous pressure can be provided to the deformation section 205. Thus, the clamping state of the clamping portion 203 and the collimator 100 is maintained in a fixed clamping state, and the connecting tongue 102 of the collimator 100 is not separated from the clamping opening 206.

When the second adjuster 500 moves to the outside of the clamping portion 203 in the Y direction, the second adjuster 500 releases the compression on the deformation section 205, and the deformation section 205 is restored. The deformation section 205 is gradually separated from the two opposite wall surfaces along the Y direction, and the bent part of the clamping portion 203 opposite to the clamping opening 206 is restored, so that the opening width L1 of the clamping opening 206 along the Y direction is restored to the original width. Connection tennons 102 is received in clamping opening 206, but since clamping member 200 does not clamp connection tennons 102, i.e., clamping state of clamping portion 203 and collimator 100 is adjustable, connection tennons 102 can move in X-direction or Z-direction within clamping opening 206, so that collimator 100 of detector module 10 can be adjusted to a target position during assembly of detector module 10.

In this way, when the deformation section 205 is provided in the clamping portion 203 and the position of the collimator 100 needs to be adjusted, the second adjuster 500 can be adjusted to release the clamping portion 203 from the fixed state of the collimator 100 and then adjust the position of the collimator 100. In the case that the collimator 100 has been adjusted to the target position, the deformation amount of the deformation section 205 may be adjusted by the second adjuster 500, so that the clamping portion 203 is deformed to clamp the connection falcon 102 of the collimator 100.

Optionally, the spacing of the deformation zones 205 is smaller than the opening width of the clamping opening 206 along the height direction of the detector module.

The deformation zone 205 may extend in a Z-direction approaching the detector module 10 so that a portion of the clip 200 opposite the clip opening 206 may more easily bend in the Z-direction.

The deformation region 205 may extend in a direction approaching the Z-direction in a direction corresponding to the direction in which the clamping opening 206 extends toward the inside of the clamping member 200. In the case of deformation of the deformation section 205, the clamping opening 206 is more likely to deform.

The height direction of the detector modules may be the Y-direction. The deformation section 205 is a distance L2 between opposite wall surfaces of the deformation section 205 in the Y direction without receiving the pressure of the second regulator 500. The value of L2 is smaller than the opening width L1 of the clamping opening 206, so that the deformation zone 205 has a relatively small space to ensure the structural strength of the clamping member 200.

In addition, the second adjusting member 500 applies a smaller pressure to the clamping member 200, so that the relatively smaller deformation region 205 is deformed, that is, the second adjusting member 500 is displaced to a smaller extent, so that the opening width L1 of the clamping opening 206 is reduced, thereby realizing adjustment of the opening width of the clamping opening 206.

In this way, by limiting the extension direction of the deformation zone 205 and the height of the cavity, on the one hand, the structural strength of the clamping member 200 can be further ensured, and on the other hand, the opening width of the clamping opening 206 can be adjusted when the second adjusting member 500 is subjected to a smaller displacement.

Optionally, the detector module 10 provided in the embodiment of the present application further includes: the detector sub-module 600 is disposed on the support 300, the detector sub-module 600 is located on the light emitting side of the collimator 100, and a space is provided between the detector sub-module 600 and the collimator 100 in the height direction of the detector module.

The detector sub-module 600 is disposed on the support 300, and the detector sub-module 600 includes materials such as cadmium zinc telluride (CdZnTe, CZT) crystals, electrode arrays, substrates, and photon counting circuitry that can accomplish the direct conversion of radiation into electrical signals. The detector sub-module 600 is configured to convert received radiation into electrical signals and is electrically connected to the circuit board 700 of the detector module 10. The circuit board 700 is used to transmit the electrical signals generated by the detector sub-module 600 to the communication means of the medical device.

There is a spacing L3 between the detector sub-module 600 and the lower surface of the collimator 100 to isolate the detector sub-module 600 from the collimator 100. Isolating the detector sub-module 600 from the collimator 100 may reduce interference of the collimator 100 to the detector sub-module 600 due to mechanical vibration, temperature variation, etc.

It should be noted that the collimator 100 needs to be precisely aligned with the electrode array. Typically, alignment of the collimator 100 and the electrode array needs to be adjusted, for example: the alignment jig 100 may be positionally adjusted by adjusting the first adjustment member 400 and/or the second adjustment member 500 to ensure accurate alignment with the electrode array.

Thus, isolating collimator 100 from detector sub-module 600 may reduce vibration and noise interference of collimator 100 to detector sub-module 600 to improve stability and signal-to-noise ratio of detector sub-module 600, thereby improving operational performance and stability of the overall detector system.

Optionally, the mounting portion 204 is provided with an avoidance gap 201, and the avoidance gap 201 and the bracket 300 define an avoidance mounting region 202, and the detector module 10 further includes: a high voltage connector 800 is disposed in the avoidance mounting region 202 and between the collimator 100 and the detector sub-module 600.

The side of the mounting portion 204 away from the clamping portion 203 is provided with a relief notch 201, and the relief notch 201 is located at the side of the mounting portion 204 for being mounted in cooperation with the bracket 300. The bracket 300 closes the avoidance gap 201 in one direction and forms the avoidance mounting region 202.

The detector module 10 also includes a high voltage connector 800, the high voltage connector 800 being disposed within the avoidance mounting region 202. The high voltage connector 800 is disposed in the avoidance mounting region 202 defined by the clip 200 and the bracket 300, and the space inside the clip 200 is reasonably utilized, so that the detector module 10 is more compact.

The high voltage connector 800 is also located at a height position between the collimator 100 and the detector sub-module 600 in the height direction of the detector module 10, further compacting the structure of the detector module 10.

The high voltage connector 800 is primarily used to connect high voltage cables in medical devices and high voltage films on the detector sub-module 600. The high-voltage film is a special insulating material, can bear high voltage and high current, and has good insulating property and mechanical property. The high voltage connector 800 transmits high voltage and high current to the detector sub-module 600 by connecting a high voltage cable and a high voltage film to ensure the normal operation of the detector module 10.

In this manner, the arrangement of the high voltage connector 800 in the relief mounting region 202 formed by the clip 200 and the bracket 300 may further utilize the structural shape and space of the clip 200, making the structural layout of the detector module 10 more rational and compact.

Alternatively, the mounting portion 204 is a non-conductive mounting portion.

The mounting portion 204 also forms the escape mounting region 202 for mounting the high-voltage connector 800. Since the high voltage connector 800 is used to connect a high voltage cable, if no insulation treatment is performed between the high voltage connector 800 and the collimator 100, spark or arc may be generated, thereby damaging the detector module 10. Therefore, it is necessary to design the mounting portion 204 as a non-conductive mounting portion to ensure that insulation processing is required between the high voltage connector 800 and the collimator 100.

Alternatively, the mounting portion 204 may be a nylon mounting portion 204.

In this way, the mounting portion 204 is made of a non-conductive material, which corresponds to the portion of the clip 200 surrounding the high voltage connector 800 being made of a non-conductive material. The clip 200 will ensure insulation between the high voltage connector 800 and the collimator 100.

Alternatively, the clamping portion 203 is an insulating clamping portion 203. That is, the clamping portion 203 may be a clamping portion 203 made of an insulating material, thereby further ensuring that the collimator 100 is isolated from high voltage electric arcs that may be generated.

Alternatively, the clamping portion 203 may also be a metal clamping portion, and since the mounting portion 204 is a non-conductive clamping portion, the clamping opening for clamping the collimator 100 is isolated from the high voltage connector 800 by the mounting portion 204. Thus, the clamping portion may be made of a metallic material to further ensure that the clamping opening 206 is aligned with the clamping of the straightener 100.

Optionally, the detector module 10 provided in the embodiment of the present application further includes: the first gasket is detachably disposed between the holder 200 and the bracket 300.

In this embodiment, when the angle of the collimator 100 needs to be adjusted, this may be achieved by inserting a first spacer between the holder 200 and the bracket 300.

Specifically, the first adjusting member 400 is adjusted to release the clamping member 200 from the fixed relation with the bracket 300, then a first spacer is inserted between the bracket 300 and the clamping member 200 to complete the adjustment of the angle of the collimator 100, and then the first adjusting member 400 is adjusted to complete the positioning and installation of the clamping member 200 and the bracket 300.

The first spacer may be provided in plurality, and each first spacer may have a different thickness. In this way, a first spacer having a suitable thickness may be selected to be interposed between the holder 200 and the bracket 300 according to actual needs, so that the angular adjustment of the collimator 100 may be variously selected.

As such, the detector module 10 may be configured with a first spacer interposed between the holder 200 and the bracket 300 to adjust the angle of the collimator 100.

Optionally, the detector module 10 further comprises a second spacer, detachably arranged in the clamping opening 206, the second spacer being located between the connecting tongue 102 and the inner wall of the clamping opening 206.

In this embodiment, when it is desired to adjust the angle of the collimator 100, this may also be achieved by inserting a second spacer between the clamping opening 206 and the connection tongue 102.

Specifically, the clamping portion 203 is released from the fixed clamping state of the connecting falcon 102 by adjusting the second adjusting member 500, then a second spacer is inserted between the clamping opening 206 and the connecting falcon 102 to complete the adjustment of the angle of the collimator 100, and then the second adjusting member 500 is adjusted to complete the clamping and fixing of the connecting falcon 102.

The second gasket may be provided in plurality, and each second gasket may have a different thickness. In this way, a second spacer of suitable thickness may be selected for insertion between the clamping opening 206 and the attachment tongue 102 as desired, thereby enabling a variety of options for angular adjustment of the collimator 100.

As such, the detector module 10 may be configured with a second spacer interposed between the clamping port 206 and the connection tongue 102 to adjust the angle of the collimator 100.

In assembling the plurality of detector modules 10, it is necessary to adjust the splice gap between the collimators 100 in adjacent detector modules 10, and the splice gap is reduced by adjusting the positions of the collimators 100 as much as possible without interference of the adjacent collimators 100. As described above, the adjustment of the splice gap may be achieved by adjusting the first adjuster 400 and/or the second adjuster 500.

In this way, the detector system of the embodiment of the application increases the coverage area of the detector system by reducing the splicing gap between the detector modules 10, thereby improving the effective acquisition amount of the scanning data and further enabling the medical equipment to obtain better imaging quality.
