Description

Technical Field

[0001] The present disclosure relates to the field of medical imaging, and in particular to a medical imaging auxiliary device for lower limbs. Background Art

[0002] At present, in the process of medical imaging of the lower limbs, in order to obtain clearer and more effective medical images of the part of interest, the operator (for example, a medical technician or a doctor) needs to constantly adjust the posture or position of the subject's lower limbs. This not only increases the workload of the operator but also greatly prolongs the imaging time of the lower limbs. In addition, in some cases, it is necessary to obtain medical images of the lower limbs under weight-bearing conditions. For example, medical images of the foot and ankle under weight-bearing conditions may better reflect the true pathological condition, which can help doctors judge the condition and provide reliable imaging information for subsequent surgery. When the subject is in a weight-bearing state, it is more difficult to adjust the posture or position of his lower limbs, and these subjects are usually unable to stand independently or for a long time, and need people or handrails to assist in standing.

[0003] At present, there are some lower limb imaging auxiliary devices, such as wooden boxes for subjects to stand on, ladders with handrails, etc. However, these imaging auxiliary devices cannot solve the problem caused by the need to adjust the posture or position of the lower limbs of the subjects. In addition, these imaging auxiliary devices are usually difficult to move and are very inconvenient to use. Utility Model Content

[0035] Figure 1 FIG. 1 shows a schematic structural diagram of an imaging auxiliary device 100 according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the imaging assisting device 100 may include an imaging assisting device 10 and an imaging detector 2 (hereinafter referred to as the detector 2). In some embodiments, the imaging assisting device 100 of the present disclosure is suitable for a lower limb medical imaging procedure. The imaging assisting device 10 may include a lower limb support 3, a rotating member 4, and an adjustment assembly 5. In an optional embodiment, the imaging assisting device 10 may also include a step member 6.

[0036] See also Figure 1 The lower limb support 3 may include a support platform 31 on which the lower limb of the subject can be placed. The support platform 31 may be formed of a low aluminum equivalent material (e.g., carbon fiber material, wood, etc.). The low aluminum equivalent material has a low absorption rate for X-rays, so the support platform 31 formed of the low aluminum equivalent material can allow X-rays to pass through without causing artifacts.

[0037] See also Figure 1 The lower limb support 3 may further include a support frame 33. The support platform 31 may be fixed between the support frames 33. The support frame 33 may be used to provide support for the support platform 31. Figure 1 In the illustrated embodiment, the support frame 33 may include four frame legs (respectively labeled 331, 332, 333, and 334), and the support platform 31 may be fixed to each of these frame legs. In other embodiments, the support frame 33 may include other numbers of frame legs as long as stable support for the support platform 31 can be provided. In an optional embodiment, such as Figure 1 As shown, an armrest portion 335 may be provided between the frame leg 331 and the frame leg 333, and an armrest portion 336 may be provided between the frame leg 332 and the frame leg 334. In some embodiments, the frame leg 331, the frame leg 333, and the armrest portion 335 may be integrally formed, for example, by bending a single metal strip to form the frame leg 331, the frame leg 333, and the armrest portion 335, respectively. Similarly, the frame leg 332, the frame leg 334, and the armrest portion 336 may also be integrally formed, for example, by bending a single metal strip to form the frame leg 332, the frame leg 334, and the armrest portion 336, respectively. In further embodiments, as Figure 1 As shown, the frame 33 may further include a crossbeam 337, which may be located between the armrest portion 335 and the armrest portion 336. The crossbeam 337 may connect the armrest portions on the left and right sides, so that the support frame 33 is formed into an integral support frame structure, which may increase the structural stability of the support frame 33. In addition, the crossbeam 337 may also be used as an additional armrest portion for the subject to support.

[0038] In some embodiments, movable wheels may be installed at the bottom of the support frame 33. For example, movable wheels may be installed at the bottom of at least one frame foot of the support frame 33 so that a user (e.g., an operator or a subject) can easily move the imaging auxiliary device 10, which can improve the convenience of using the imaging auxiliary device 10. As an example, Figure 1 It is exemplarily shown that movable wheels are installed at the bottom of two frame legs in the support frame 33, wherein the frame leg 331 is installed with a movable wheel 351, and the frame leg 332 is installed with a movable wheel 352.

[0039] Figure 8 FIG. 2 shows a schematic diagram of the structure of an imaging auxiliary device 200 according to some other exemplary embodiments of the present disclosure. Figure 8 As shown, the imaging auxiliary device 200 may include an imaging auxiliary device 20 and an imaging detector 2. The imaging auxiliary device 20 may include a lower limb support 9, a rotating member 4, an adjustment component 5 ( Figure 8 not shown).

[0040] The lower limb support 9 may include a support platform 91 on which the lower limbs of the subject can be placed. The support platform 91 may be similar to the support platform 31 described above. The lower limb support 9 may also include a footrest 92, which may be placed on the support platform 91, and the subject's feet may be placed on the footrest 92, for example, the subject may stand on the footrest 92. The support platform 91 and / or the footrest 92 may be formed of a low aluminum equivalent material (e.g., carbon fiber material, wood, etc.). Low aluminum equivalent materials have a low absorption rate for X-rays, so the support platform 91 and / or the footrest 92 formed of low aluminum equivalent materials can allow X-rays to pass through without causing artifacts.

[0041] The lower limb support 9 may further include a support frame 93, between which the support platform 91 may be fixed, and the support frame 93 may be used to provide support for the support platform 91. The support frame 93 may include four frame legs (respectively marked as 931, 932, 933 and 934), to each of which the support platform 91 may be fixed. In other embodiments, the support frame 93 may include other numbers of frame legs, as long as stable support for the support platform 91 can be provided. The bottom of the support frame 93 may also be equipped with movable wheels.

[0042] The imaging assisting device 20 further includes an armrest frame 7, which may include an armrest portion 71 and an armrest portion 73. The distance between the armrest portion 71 and the armrest portion 73 can be used to accommodate and place the lower limb support 9, so that the subject can hold the armrest portions 71 and the armrest portions 73 on both sides when using the lower limb support 9, thereby ensuring the safety of the subject. Additionally, the armrest frame 7 may also include an armrest portion 75, which may be located between the armrest portion 71 and the armrest portion 73 for use by the subject.

[0043] Figure 8 The detector 2, the rotating member 4 and the adjusting assembly 5 in the imaging auxiliary device 200 shown can be used with Figure 1 The detector 2, the rotating member 4 and the adjusting assembly 5 in the imaging assisting device 100 shown are the same. The detector 2 can be mounted on the rotating member 4. The rotating member 4 can rotate relative to the supporting platform 31 of the lower limb support 3, thereby driving the detector 2 mounted on the rotating member 4 to rotate relative to the supporting platform 31 of the lower limb support 3.

[0044] The following reference Figure 2 The rotating member 4 will be described in detail. Figure 2 FIG. 2 is a partial exploded schematic diagram of an imaging assisting device 200 according to some other exemplary embodiments of the present disclosure. Figure 2 Mainly Figure 8 The structure of the lower limb support member in the embodiment shown is used as an example for explanation, but those skilled in the art should understand that Figure 2 The lower limb support 9 and the support frame 93 can be replaced by Figure 1 The lower limb support 3 shown has a corresponding structure to the support frame 33 .

[0045] The rotating member 4 may include a mounting portion, which may be used to mount the detector 2. Figure 2 As shown, the mounting portion may include a mounting groove 41 and a mounting groove 42, and the mounting groove 41 and the mounting groove 42 may be used to accommodate the detector 2. Each of the mounting groove 41 and the mounting groove 42 may have a hinge portion ( Figure 2 (not shown). Figure 2 In the illustrated example imaging aid 20, the mounting slot 41 may be hinged to the frame foot 931 of the support frame 93 via its hinged portion, and the mounting slot 42 may be hinged to the frame foot 932 of the support frame 93 via its hinged portion. Figure 1 In the illustrated example imaging assisting device 10 , the mounting slot 41 may be hinged to the frame leg 331 of the supporting frame 33 via its hinged portion, and the mounting slot 42 may be hinged to the frame leg 332 of the supporting frame 33 via its hinged portion.

[0046] The hinged connection between the mounting groove and the frame support foot in this article can be realized by using a hinged structure known in the art, which will not be described in detail here. By utilizing the hinged connection between the mounting groove of the rotating member 4 and the frame support foot of the support frame 33 (or the support frame 93), the rotating member 4 can rotate relative to the support frame 33 (or the support frame 93), and then can rotate relative to the support platform 31 fixed to the support frame 33 (or the support platform 91 fixed to the support frame 93). Figure 2 , the detector 2 may have a first side 21 and a second side 22 opposite to each other. The mounting groove 41 may be configured to accommodate at least a portion of the first side 21 of the detector 2, and the mounting groove 42 may be configured to accommodate at least a portion of the second side 22 of the detector 2. When the detector 2 is mounted to the rotating member 4 (e.g. Figure 1 As shown in the figure, the detector 2 can rotate with the rotating member 4 relative to the supporting platform 31 (or the supporting platform 91), so that the surface 23 of the detector 2 is at different angles relative to the top surface 311 of the supporting platform 31 (or the top surface 911 of the supporting platform 91).

[0047] The adjustment assembly 5 can be used to define a plurality of rotational positions of the detector 2, such as a 45° position, a 60° position, a 75° position, a 90° position, a 120° position, etc. Each of these rotational positions can correspond to a corresponding angle formed by the surface 23 of the detector 2 relative to the top surface 311 of the support platform 31 (or the top surface 911 of the support platform 91), such as any angle between 45° and 135°. Figure 1 As shown, the adjustment assembly 5 limits the detector 2 to a position of about 90°, at which point the angle formed by the surface 23 of the detector 2 relative to the top surface 311 of the support platform 31 is about 90°.

[0048] The detector 2 can be used to receive signals generated during medical imaging, such as X-rays from an X-ray source, gamma rays from a gamma ray source, photons or other forms of radiation, and the detector 2 can convert the received signals into electrical signals. These electrical signals can then be processed by, for example, a computer to form a visualized medical image.

[0049] The following reference Figure 3 The adjustment assembly 5 is described in detail. Figure 3 A schematic structural diagram for illustrating the adjustment assembly 5 is shown when viewed from an oblique perspective.

[0050] See also Figure 3, the adjustment component 5 may be located below the support platform 31 (or the support platform 91). The adjustment component 5 may include two fixing members 51. The two fixing members 51 have the same structure and may be symmetrically fixed to both sides below the support platform 31 (or the support platform 91). Each fixing member 51 may include a groove 511, and the groove 511 may be configured to accommodate the movable member 53. Figure 3 In the illustrated embodiment, the fixing member 51 is configured to have a sector-shaped cross section, and the groove portion 511 is an arcuate groove and extends along the arc edge of the sector-shaped cross section of the fixing member 51. Correspondingly, the movable member 53 is configured as an arcuate movable member so as to be accommodated in the arcuate groove.

[0051] Although this article Figure 3 The adjustment component 5 is described by taking the fixed member 51 with a fan-shaped cross-section as an example. However, in other embodiments, the fixed member 51 in the adjustment component 5 may be configured to have a cross-section of other shapes. For example, the fixed member 51 may be configured to have a triangular cross-section; correspondingly, the groove 511 may extend along the bottom side of the triangular cross-section, and the movable member 53 may be configured as a strip-shaped movable member. For another example, the fixed member 51 may be configured to have a square cross-section; correspondingly, the groove 511 may extend along the bottom side of the square cross-section, and the movable member 53 may be configured as a strip-shaped movable member. For another example, the fixed member 51 may be configured to have a semicircular cross-section; correspondingly, the groove 511 may extend along the round side of the semicircular cross-section, and the movable member 53 may be configured as an arc-shaped movable member.

[0052] The following reference Figure 4 The movable member 53 is described in detail. Figure 4 Shows Figure 3 A schematic structural diagram of the movable part 53 in the adjusting assembly 5.

[0053] See also Figure 4 , the movable member 53 may include a plurality of limit portions 531, each for limiting a plurality of rotational positions of the detector 2. The limit portions 531 may be distributed along the arc-shaped extension direction of the movable member 53, for example, in a uniform manner or in an uneven manner. Figure 3 As shown in FIG. 5 , these limiting portions 531 can be distributed along the groove extension direction of the groove portion 511, and are respectively used to limit multiple rotation positions of the detector 2. Each limiting portion 531 can be used to prevent the detector 2 mounted on the rotating member 4 from further rotating at the limiting portion 531, thereby limiting the detector 2 at a rotation position. As a non-limiting example, Figure 4As shown, the limiting portion 531 may be a limiting groove, and the two ends of the limiting groove may have groove walls 532 and 534, respectively. Each limiting groove may be configured to accommodate at least a portion of the bottom of the detector 2 or to accommodate at least a portion of the bottom of the rotating member 4 for mounting the detector 2. When at least a portion of the bottom of the rotating member 4 on which the detector 2 is mounted or at least a portion of the bottom of the detector 2 is placed in any one of the plurality of limiting grooves of the movable member 53, the groove wall 532 or 534 of the limiting groove may prevent the detector 2 from further rotating at the limiting groove, thereby fixing the detector 2 at a rotational position corresponding to the limiting groove. In other words, the detector 2 may have a plurality of rotational positions, and when in each of the plurality of rotational positions, the detector 2 may be located at a corresponding limiting portion of a plurality of limiting portions (e.g., limiting grooves) and at a corresponding angle relative to the support platform 31. For example, when the detector 2 is in a position such as Figure 3 In the first rotation position (ie, 90° position) shown, the detector 2 may be located at the first limit portion 531a and at a first angle (ie, approximately 90°) relative to the support platform 31 (or support platform 91).

[0054] Although this article Figure 3 and Figure 4 The limiting portion 531 is described by taking the limiting groove as an example. However, the present invention is not limited thereto. In other embodiments, the limiting portion 531 may have other structures besides the limiting groove, as long as the structure can cooperate with the rotating member 4 on which the detector 2 is mounted or with the detector 2, so as to prevent the detector 2 mounted on the rotating member 4 from further rotating at the limiting portion.

[0055] When in use, the subject can place the lower limbs (e.g., ankle) on the support platform 31 (or support platform 91), for example, the subject can stand on the support platform 31 (or support platform 91), and the operator (e.g., medical technician or doctor) can rotate the detector 2 mounted on the rotating member 4 to rotate the detector 2 to the desired angle. When the detector 2 is rotated to the desired angle, the operator can place the bottom of the detector 2 or the rotating member 4 at the limit portion 531 of the movable member 53 corresponding to the desired angle, so that the detector 2 can be fixed at the desired angle. Subsequently, the operator can use the imaging device including the detector 2 to obtain a medical image of the part of interest. In this process, the operator can quickly and easily adjust the angle of the detector 2 to obtain a clearer and more effective medical image of the part of interest, which greatly reduces the operator's workload and can also reduce imaging time.

[0056] The rotational position adjustment accuracy of the detector 2 may refer to the minimum angle difference between multiple angles of the detector 2 corresponding to multiple rotational positions of the detector 2. The rotational position adjustment accuracy may be affected by the distribution density of the multiple limiting portions 531 on the movable member 53. The denser the multiple limiting portions 531 on the movable member 53 are distributed (which means the shorter the distance between adjacent limiting portions 531), the smaller the angle difference that the detector 2 can span between adjacent limiting portions 531, and the higher the rotational position adjustment accuracy of the detector 2. Therefore, the rotational position adjustment accuracy of the detector 2 may be improved by increasing the distribution density of the multiple limiting portions 531 on the movable member 53 (for example, the distance between adjacent limiting portions 531 in the multiple limiting portions 531 may be shortened). However, the distribution density of the multiple limiting portions 531 on the movable member 53 is further affected by the structural size of the limiting portion 531 itself. For example, the limiting portion 531 configured as a limiting groove may have to have a minimum size in the extension direction of the movable member 53 so as to be able to stably fix the detector 2. The limiting portion 531 that is required to have a minimum size limits the distribution density of the plurality of limiting portions 531 on the movable member 53 , thereby limiting the adjustment accuracy of the rotational position of the detector 2 .

[0057] In order to further improve the rotation position adjustment accuracy of the detector 2, the present invention further proposes that the movable member 53 can move a preset distance relative to the groove 511, thereby realizing double adjustment of the detector 2. The first adjustment of the detector 2 can be realized by providing a plurality of limit portions 531 on the movable member 53 for limiting a plurality of rotation positions of the detector 2, and the second adjustment of the detector 2 can be realized by moving the movable member 53 including the plurality of limit portions 531 in the groove 511.

[0058] In some embodiments, a plurality of positioning parts may be defined in the groove 511 of the fixing member 51. Each of these positioning parts may be used to fix the movable member 53 that has moved a corresponding preset distance relative to the groove 511. These positioning parts may be distributed along the groove extension direction of the groove 511. The movable member 53 may have a structure that matches each of these positioning parts of the groove 511. As a non-limiting example, the positioning part may be a positioning hole, and the bottom of the movable member 53 may have a positioning column that matches the positioning hole. When the positioning column at the bottom of the movable member 53 is inserted into one of the plurality of positioning holes in the groove 511 of the positioning member 51, the movable member 53 may be fixed at the positioning hole. Although the fixed positioning of the movable member 53 at the positioning part of the groove 511 is described herein with a pair of positioning matching structures of the positioning hole and the positioning column. However, the utility model is not limited thereto. After reading the contents of the utility model, those skilled in the art may set other positioning matching structures as needed, such as a positioning matching structure including two positioning holes and a screw.

[0059] By providing positioning parts at multiple positions distributed along the groove extension direction in the groove portion 511 of the fixing member 51, the movable member 53 can be fixed at any one of the multiple positions in the groove portion 511 of the fixing member 51. Compared with a movable member 53 having only a single fixed position (i.e., the movable member 53 can only be fixed at a single position in the groove portion 511 of the fixing member 51), a movable member 53 having multiple fixed positions along the groove extension direction of the groove portion 511 can allow the detector 2 to have more rotational positions, and the added one or more rotational positions can be located between two originally adjacent rotational positions (two adjacent rotational positions in the case of a movable member 53 having only a single fixed position), thereby improving the rotational position adjustment accuracy of the detector 2. The improvement in the rotational position adjustment accuracy of the detector 2 can further allow the operator to use more precise detector angle adjustment to obtain more ideal medical images of the subject.

[0060] Although this article combines the above Figure 3 The described adjustment assembly 5 includes two fixed members 51 and two movable members 53. However, in other embodiments, the adjustment assembly 5 may include only one fixed member and one movable member. The position and / or size of the single fixed member and the single movable member may be designed to stably fix the detector 2 at a certain rotational position. For example, the single fixed member and the single movable member may be positioned so that the stopper on the single movable member fixes the detector 2 at the bottom center of the detector 2. For another example, the width of the groove of the single fixed member may be much larger than Figure 3 The width of the groove portion 511 of the fixing member 51 shown, such as the width of the groove portion 511 of the fixing member 51, can be Figure 3 The position of the fixed member 51 on the left side shown in the figure is extended to the position of the fixed member 51 on the right side; accordingly, the width of the single movable member can be much larger than Figure 4 The width of the movable member 53 shown is measured along the W direction, such as the width of the single movable member can be greater than or equal to the width of the detector 2, so that the limit groove of the movable member 53 can completely accommodate the bottom of the detector 2. In other embodiments, the adjustment assembly 5 can include more than two fixed members and more than two movable members.

[0061] In other embodiments, the adjustment assembly 5 may not have a movable part, but only a fixed part, and the fixed part may further include a plurality of limit parts, which may be similar to the limit parts 531 located on the movable part 53 described above. Each limit part can be used to prevent the detector 2 mounted on the rotating member 4 from further rotating at the limit part, so as to limit the corresponding rotational position of the detector 2.

[0062] See also Figure 3 and Figure 5 , the support platform 31 (or the support platform 91) may have a mounting portion 33 at the bottom surface, and the mounting portion 33 is used to mount the detector 2. The mounting portion 33 may include a mounting groove 331 and a mounting groove 333, and the two mounting grooves may be symmetrically located on both sides of the bottom surface of the support platform 31 (or the support platform 91) and are substantially parallel to each other. The mounting groove 331 may be configured to accommodate at least a portion of the first side 21 of the detector 2, and the mounting groove 333 may be configured to accommodate at least a portion of the second side 22 of the detector 2. When the detector 2 is mounted to the mounting portion 33 at the bottom surface of the support platform 31, at least a portion of the first side 21 of the detector 2 may be located in the mounting groove 331, and at least a portion of the second side 22 of the detector 2 may be located in the mounting groove 333. The detector 2 may be located below the support platform 31 and at an angle of 0° relative to the support platform 31, such as Figure 5 shown. Figure 5 The schematic diagram shows a state where the detector 2 is at an angle of about 0° relative to the supporting platform 91 .

[0063] See also Figure 1 The imaging assisting device 10 may further include a step member 6, which may be located below the support platform 31 when in use, so as to serve as an intermediate step for the subject to enter the higher support platform 31, thereby improving the safety of the subject during lower limb imaging. Figure 1 , the step member 6 may include a panel 61 and two step legs (respectively labeled 62 and 64). The step legs 62 and the step legs 64 may extend vertically from the bottom surface of the panel 61. The step legs 62 and the step legs 64 may be symmetrically located on the left and right sides of the panel 61 to provide stable support for the panel 61. In other embodiments, the step member 6 may include more than two step legs to further improve the stability of the step member 6.

[0064] In some embodiments, the step member 6 may be hinged to the support frame 33. The step member 6 may include a hinge assembly. Figure 1 As shown, the hinge assembly may include a first hinge 66 and a second hinge 68. One end of the first hinge 66 may be hinged to a frame foot 333 in the support frame 33, and the other end may be connected to the panel 31 (e.g., fixedly connected or hinged). One end of the second hinge 68 may be hinged to a frame foot 334 in the support frame 33, and the other end may be connected to the panel 31 (e.g., fixedly connected or hinged).

[0065] Through the hinged cooperation relationship between the hinge assembly and the frame support foot of the support frame 33, the step member 6 can be Figure 1 Slide the expanded state shown to Figure 6 The folded state, wherein Figure 6FIG. 2 shows a schematic diagram of a structure of a step member 6 in a folded state according to an exemplary embodiment of the present disclosure. When the step member 6 is in an unfolded state, as shown in FIG. Figure 1 As shown, the height of the panel 61 of the step member 6 may be lower than the height of the support platform 31, and the top surface 611 of the panel 61 of the step member 6 may be staggered with the top surface 311 of the support platform 31 in the height direction. For example, the panel 61 of the step member 6 may be located obliquely below the support platform 31. The step member 6 in the unfolded state may be used as an intermediate step for the subject to enter the higher support platform 31, which may improve the safety of the subject during lower limb imaging. When the step member 6 is in the folded state, as shown in FIG. Figure 6 As shown, the top surface 611 ( Figure 6 The step member 6 (not shown) can contact the top surface 611 of the support platform 31, so that the panel 61 of the step member 6 is folded at the support platform 31. When the imaging auxiliary device 10 is not needed, the step member 6 can be placed in a folded state. Since the panel 61 of the step member 6 in the folded state can be folded at the support platform 31, the space occupied by the imaging auxiliary device 10 can be reduced and the convenience of carrying or moving the imaging auxiliary device 10 can be improved.

[0066] Figure 7 Schematic diagrams of the structure of the step member 8 in an unfolded state according to some other exemplary embodiments of the present disclosure are shown.

[0067] See also Figure 7 , the step member 8 may include a panel 81 and two step legs (respectively labeled 82 and 84). The panel 81 and the two step legs 82 and 84 of the step member 8 may be similar to the above combination Figure 1 The panel 61 and two step legs 62 and 64 are shown. In addition, the step member 8 may include more than two step legs to further improve the stability of the step member 8. Unlike the step member 6 that is hinged to the support frame, the step member 8 can be slidably connected to the support frame. The step member 8 may include a slide assembly that can be used to mount the panel 81 of the step member 8. Figure 7 As shown, the slide groove assembly may be located below the support platform 91 and include a first slide groove 86 and a second slide groove 88, and the first slide groove 86 may be substantially parallel to the second slide groove 88. The panel 81 may include a first side 811 and a second side 813, and the first side 811 may be substantially parallel to the second side 813. The first slide groove 86 may be used to accommodate at least a portion of the first side 811 of the panel 81 and allow the first side 811 to slide therein, and the second slide groove 86 may be used to accommodate at least a portion of the second side 813 of the panel 81 and allow the second side 813 to slide therein. Through the cooperation between the panel 81 and the slide groove assembly, the step member 8 can be moved from Figure 7The step member 8 is in the unfolded state, as shown, and slides to the folded state (not shown). Figure 7 As shown, the height of the panel 81 of the step member 8 may be lower than the height of the support platform 91, and the top surface 811 of the panel 81 of the step member 8 may be staggered with the top surface 911 of the support platform 91 in the height direction. For example, the panel 81 of the step member 8 may be located obliquely below the support platform 91. The step member 8 in the unfolded state can be used as an intermediate step for the subject to enter the higher support platform 91, which can improve the safety of the subject during lower limb imaging. When the step member 8 is in the folded state, the height of the panel 81 of the step member 8 may be lower than the height of the support platform 91, and at least a portion of the top surface 811 of the panel 81 of the step member 8 may overlap with the top surface 911 of the support platform 91 in the height direction, for example, the panel 81 of the step member 8 may be located directly below the support platform 31. This can allow the panel 81 of the step member 8 to be hidden under the support platform 91. When the imaging auxiliary device 10 is not needed, the step member 8 can be placed in a folded state. Since the panel 81 of the step member 8 in the folded state can be hidden under the supporting platform 91 , the space occupied by the imaging auxiliary device 20 can be reduced and the convenience of carrying or moving the imaging auxiliary device 20 can be improved.

[0068] Although the above combination Figure 1 and Figure 6 The step member 6 is hinged to the support frame 33, combined with Figure 7 The step member 8 is described as being slidably connected to the support frame 93. However, it should be understood that Figure 1 and Figure 6 The step member 6 shown in FIG. 1 can also be hinged to Figure 7 The support frame 93 shown, Figure 7 The step member 8 shown can also be slidably connected to the Figure 1 and Figure 6 The support frame 33 shown in FIG.

[0069] In other embodiments of the present disclosure, the step member may be fixedly connected to the lower limb support member, for example, the panel of the step member may be fixedly connected to the support frame of the lower limb support member (for example, the support frame 33 or the support frame 93), the height of the panel of the step member may be lower than the height of the support platform and the top surface of the panel of the step member may be staggered with the top surface of the support platform in the height direction, so that the step member is fixed in the expanded state. In other words, the step member fixedly connected to the lower limb support member may only have an expanded state.

[0070] According to an embodiment of the present disclosure, an imaging system is also provided, which may include an imaging device and the imaging auxiliary device 10 or the imaging auxiliary device 20 as described above. The imaging device may include the imaging detector 2 and a ray source used in conjunction with the imaging auxiliary device 10 as described above.

However, it should be understood that various modifications may be made to the exemplary embodiments described above without departing from the spirit and scope of the present disclosure. For example, if the described techniques are performed in a different order and / or if the components in the described systems, architectures, devices, or circuits are combined in different ways and / or replaced or supplemented by other components or their equivalents, suitable results may be achieved, and accordingly, these modified other implementations also fall within the scope of protection of the claims.
