[0037] The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. However, the present disclosure may be implemented in various ways and should not be construed as limited to the embodiments described herein. These embodiments are provided to make the disclosure more thorough and complete, and to fully convey the scope of the disclosure to those skilled in the art. In the drawings, the thickness and area of layers may be enlarged for clarity. Throughout the specification, the same reference numerals are used to denote the same elements. For different embodiments, elements may have different relationships and different positions.
[0038] This application primarily aims to provide a novel collimator with adjustable slit width, enabling its use in confined spaces. Furthermore, it allows for multi-degree-of-freedom adjustment in conjunction with an optomechanical system, ultimately achieving linear adjustment of the optomechanical system, collimator, and detector. Simultaneously, it reduces the number of collimator specifications and lowers manufacturing costs.
[0039] The collimator assembly in this application allows adjustment of the collimator slit width within the range of 0.6mm-1.2mm, and also allows adjustment of the collimator's position on the optomechanical base to align with the optomechanical components, thereby achieving alignment in one direction, such as the horizontal direction. Furthermore, it enables small-angle rotational adjustments of the collimator, such as fine-tuning deflection in the vertical direction. Finally, by adjusting the X-ray tube base in two directions, the optomechanical system including this collimator assembly achieves more accurate alignment of the optomechanical system, collimator, and detector.
[0040] Figure 1 This is a top view of a collimator assembly according to an exemplary embodiment of the present disclosure. Figure 2 It is along Figure 1 The cross-sectional view shown is taken along the BB line. Figure 3 It is along Figure 1 The cross-sectional view shown is taken along line AA. Figure 4 This is a perspective view of a collimator assembly according to an exemplary embodiment of the present disclosure. Figure 5 This is a perspective view of a collimator assembly mounted on an optical engine base according to an exemplary embodiment of the present disclosure.
[0041] like Figures 1 to 5 As shown, in an embodiment of this application, the collimator assembly 1 includes: at least one position adjustment portion 11, the at least one position adjustment portion 11 being located at the end of the collimator assembly 1 for adjusting the position of the collimator assembly 1; and a collimator body portion 12, on which the at least one position adjustment portion 11 is located, the collimator body portion 12 including a first adjustment member 121, a left collimator member 122, a right collimator member 123, and a collimator component located between the left collimator member 122 and the right collimator member 123. The collimator component 123 has an adjustment hole 124. The left collimator component 122 and the right collimator component 123 are arranged side by side and have a collimator slit 125 between them. The adjustment component passes through the corresponding adjustment hole 124 to adjust the width of the collimator slit 125. The shielding box 13 is fixed to the collimator body part 12 and is located on the side opposite to the position adjustment part 11. The shielding box 13 has gaps 131 at the top and bottom corresponding to the collimator slit 125.
[0042] In one embodiment of this application, such as Figure 2 and Figure 3As shown, the collimator is composed of multiple components, such as a position adjustment part 11, a collimator body part 12, and a shielding box 13. The collimator body part 12 includes a first adjustment component 121, a left collimator component 122, a right collimator component 123, and multiple adjustment holes 124 located on the left and right collimator components 122 and 123. The first adjustment component 121 can be a screw, bolt, or bolt. A collimator slit 125 is provided between the left and right collimator components 122 and 123. By adjusting the screws located on the left and right collimator components 122 and 123 respectively, the positions of the left and right collimator components 122 and 123 relative to each other are adjusted, thereby adjusting the distance between the left and right collimator components 122 and 123, that is, adjusting the width of the collimator slit 125 so that the collimator slit width is within the range of 0.6mm-1.2mm.
[0043] In one embodiment of this application, such as Figure 4 and Figure 5 As shown, the collimator component may include one or more position adjustment portions 11 for moving the collimator assembly 1 in one direction. Each position adjustment portion 11 includes a boss portion 111, the boss portion 111 having a through hole 112 inside its portion protruding from other parts of the collimator, at least a portion of the inner surface of the through hole 112 being provided with a thread 1121. Providing a portion of the thread instead of the entire thread reduces machining and also prevents the threaded portion from being too long, facilitating assembly and adjustment. Alternatively, in other embodiments, the entire inner surface of the through hole 112 is provided with threads.
[0044] In one embodiment of this application, such as Figures 2 to 5 As shown, the collimator assembly 1 may include two position adjustment portions 11, each of which includes a boss portion 111. In other words, the collimator assembly 1 may include a boss portion 111 at each end for smoother and more stable movement of the collimator assembly 1 in one direction. Each through hole 112 is provided with a threaded second adjustment member 113, i.e., a screw or bolt. This screw or bolt can not only fix the collimator assembly 1, for example, to the optical engine base 21, but also adjust the position of the collimator assembly 1 in one direction, for example, adjusting the position of the collimator assembly 1 along the axial direction of the through hole 112. The collimator assembly 1 moves along the axial direction of the through hole 112 through the engagement of the screw or bolt with the thread in the through hole 112.
[0045] In one embodiment of this application, such as Figures 2 to 5As shown, the rotation of the collimator assembly 1 in the plane containing the slit width is adjusted by rotating the corresponding second adjustment mechanisms in the through holes 112 of the first and second bosses by different angles. For example, when the collimator is placed horizontally, by rotating the bolts in the first and second bosses respectively, the collimator will rotate slightly in the horizontal plane when the two bolts rotate at different angles, thereby achieving small-angle rotation of the collimator. Alternatively, when the collimator is placed vertically, fine-tuning of the deflection in the vertical direction can be achieved.
[0046] In one embodiment of this application, such as Figures 2 to 5 As shown, the position adjustment part 11 also includes a flat plate part 114, which has a plurality of flat plate holes 1141 and an elongated slit 1142 corresponding to the collimator slit 125. The flat plate holes 1141 correspond to the adjustment holes 124 respectively. A boss part 111 may be located at the end of the flat plate part 114; preferably, a boss part 111 is provided at each end of the flat plate part 114. The flat plate part 114 has flat plate holes 1141 corresponding to the adjustment holes 124, so that the screw can pass through the adjustment holes 124 and the flat plate holes 1141 to adjust the flat plate part 114, the left collimator member 122, and the right collimator member 123 together. The flat plate part 114 may include a left flat plate part and a right flat plate part, corresponding to the left collimator member 122 and the right collimator member 123 respectively. An elongated slit 1142 is left between the left flat plate part and the right flat plate part to correspond to the collimator slit 125. Alternatively, in other embodiments, the plate portion 114 is formed from a single plate, wherein an elongated slit 1142 is formed that is greater than or equal to the collimation slit width.
[0047] In one embodiment of this application, such as Figures 2 to 5 As shown, the collimator has multiple adjustment holes 124, wherein the inner surface of each hole and each of the plate holes 1141 is smooth, that is, the adjustment holes 124 and the plate holes 1141 are not threaded holes. The first adjustment member 121 passes through the plate holes 1141 and the adjustment holes 124 and is fixed to the shielding box 13 by a nut.
[0048] In one embodiment of this application, such as Figures 2 to 5 As shown, the left collimator member 122 has a first protrusion 1221 near the collimator slit 125, and the right collimator member 123 has a second protrusion 1231 near the collimator slit 125, the first protrusion 1221 and the second protrusion 1231 surrounding the collimator slit 125 therein. Correspondingly, the plate portion 114 has an opening through which the first protrusion 1221 and the second protrusion 1231 pass.
[0049] This application also provides an optomechanical adjustment device 2. Figure 6 This is a perspective view of an optomechanical adjustment apparatus according to an exemplary embodiment of the present disclosure. Figure 7 This is a perspective view of the optomechanical adjustment device according to an exemplary embodiment of the present disclosure from another angle. Figure 8 This is a top view of an optomechanical adjustment apparatus according to an exemplary embodiment of the present disclosure. Figure 9 It is along Figure 8 The cross-sectional view shown is taken along line AA. Figure 10 This is a side view of an optomechanical adjustment apparatus according to an exemplary embodiment of the present disclosure. Figure 11 This is a perspective view of a vertically arranged optical engine base on which an optical engine adjustment device is mounted, according to an exemplary embodiment of the present disclosure.
[0050] like Figures 6 to 11 As shown, the optical-mechanical adjustment device 2 includes: a base 21, an X-ray tube 211 and an X-ray tube support 212 disposed on the base 21; an X-ray tube horizontal adjustment component 22, which includes a first horizontal adjustment component 221 and a plurality of second horizontal adjustment components 222 located on the X-ray tube support 212, wherein the first horizontal adjustment component 221 connects the X-ray tube support 212 to the base 21, and the second horizontal adjustment components 222 are used to adjust the position of the X-ray tube 211 relative to the X-ray tube support 212; and the aforementioned collimator assembly 1, which is located on the base 21.
[0051] In one embodiment of this application, such as Figures 6 to 11 As shown, the base 21 of the optical engine is vertically arranged, the X-ray tube support 212 is mounted on the base 21, and the X-ray tube 211 is mounted on the X-ray tube support 212, which in turn is mounted on the base 21. The first horizontal adjustment member 221 connects the X-ray tube support 212 to the base 21 on one hand, and can adjust the position of the X-ray tube support 212 relative to the base 21 on the other hand, preferably to a horizontal position. The first adjustment member 121 includes a third adjustment member 2212 and a threaded hole provided in the X-ray tube support 212. For example, the third adjustment member 2212 is a screw or bolt. By rotating the screw or bolt, the X-ray tube support 212 is installed on the base 21. By tightening the screw or bolt, the X-ray tube support 212 is loosened, allowing it to move horizontally, thereby adjusting the horizontal position of the X-ray tube support 212.
[0052] In one embodiment of this application, such as Figures 6 to 11As shown, the second horizontal adjustment member 222 is disposed on both sides of the ball tube 211, including a fourth adjustment member 2221 and an elongated adjustment hole located on the ball tube support 212. The fourth adjustment member 2221 passes through the elongated adjustment hole, thereby adjusting the horizontal position of the ball tube 211 relative to the ball tube support 212. Specifically, the fourth adjustment member 2221 may include a bolt or a screw. For example, the third adjustment member 2212 is a screw or bolt. By rotating the screw or bolt, the ball tube 211 is installed on the ball tube support 212. Threaded elongated holes 2222 are provided on the supports on both sides of the ball tube 211. The longitudinal direction of the holes is along the horizontal direction. The second horizontal adjustment member 222 passes through the elongated holes 2222 to install the ball tube 211 onto the ball tube support 212, and also allows the ball tube 211 to move along the horizontal direction, thereby adjusting the horizontal position of the ball tube 211.
[0053] like Figure 9 As shown, the axis of the X-ray tube 211 is perpendicular to the slit width direction of the collimator assembly 1. Rays emitted from the X-ray tube 211 pass through the collimator slit 125 and continue forward. As shown, the slit width is related to the distance from the collimator assembly 1 to the X-ray tube 211; the closer to the X-ray tube 211, the narrower the slit.
[0054] In one embodiment of this application, such as Figure 11 As shown, the optomechanical adjustment device 2 may also include a vertical adjustment component 23, which includes a screw and a nut. The screw passes through the X-ray tube support 212 and is connected to the base 21 by the nut, and adjusts the vertical position of the X-ray tube 211 relative to the base 21.
[0055] In one embodiment of this application, such as Figure 11 As shown, the base 21 of the optical engine can be set on a plane perpendicular to the horizontal plane. That is, it can be set in a vertical plane.
