Description

Technical Field

[0002] Conventional medical scanning equipment uses the patient in a supine position for examination. Due to the influence of gravity, when the human body is in a standing position and a supine position, the position of the anatomical structure changes due to the difference in body position, and the position and shape of the internal organs of the body will also change accordingly. The different forces on various parts of the skeletal muscle system may cause changes in morphological structure. Standing medical scanning equipment refers to changing the patient's examination from the original supine position to a standing or semi-sitting position. The medical scanning equipment is changed from being fixed on the ground and rotating around the patient to achieve X-ray penetration. The medical scanning equipment simultaneously achieves linear motion along the patient's axis and rotation around the patient to achieve X-ray penetration. Standing medical scanning equipment can identify the real state of the human body's weight-bearing position, especially the spine and lower limbs, and is used for differential diagnosis of various diseases such as orthopedics and tumors.

[0039] Figure 1 A schematic diagram of a standing medical scanning device provided in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the standing medical scanning device includes a safety camera assembly 10, a vertical support 20, a gantry 30 and a patient support 40. The patient support 40 is the patient's standing position, and the standing medical scanning device realizes the patient scanning process by lifting the patient or moving the frame. The safety camera assembly 10 is fixed to the top of the vertical support 20, wherein the safety camera assembly 10 includes a plurality of depth cameras, and the patient support 40 is located in the image acquisition area of ​​the depth camera, and the depth camera can obtain the depth image data of the patient's standing position.

[0040] like Figure 1 As shown, the vertical bracket 20 is fixed on the ground and extends in the vertical direction, the gantry 30 is fixed on a mounting surface of the vertical bracket 20 close to the ground, and the gantry 30 extends in the horizontal direction. The patient bracket 40 is installed between the gantry 30 and the ground and can be translated in the horizontal plane, and the safety camera assembly 10 is installed and fixed on the top of the vertical bracket 20.

[0041] Figure 2 A schematic diagram of the structure of a safety camera assembly of a standing medical scanning device provided by an embodiment of the present disclosure, such as Figure 2 As shown, the safety camera assembly 10 includes a safety camera adjustment device 100 and a plurality of depth cameras 200 . The plurality of depth cameras 200 are fixed on the safety camera adjustment device 100 .

[0042] For example, Figure 2 As shown, the security camera assembly 10 includes three depth cameras 200 , which can collect depth image data of an image collection area.

[0043] In other embodiments, the safety camera assembly 10 may further include two depth cameras 200 , four depth cameras 200 , or more than four depth cameras 200 . The present disclosure does not specifically limit the number of depth cameras 200 in the safety camera assembly 10 .

[0044] The safety camera adjustment device 100 can move along the X-axis, move along the Y-axis, rotate along the X-axis, rotate along the Y-axis, and rotate along the Z-axis. Since the depth camera 200 is fixed on the safety camera adjustment device 100, the safety camera adjustment device 100 can drive multiple depth cameras 200 to move along the X-axis, move along the Y-axis, rotate along the X-axis, rotate along the Y-axis, and rotate along the Z-axis to adjust the position of the multiple depth cameras 200 along the X-axis, the position along the Y-axis, the rotation angle along the X-axis, the rotation angle along the Y-axis, and the rotation angle along the Z-axis.

[0045] The specific structure of the safety camera adjustment device 100 is described in detail below with reference to several specific embodiments.

[0046] Continue to see Figure 2 The safety camera adjustment device 100 includes a translation bracket 110, a first rotating platform 121, a second rotating platform 122 and a mounting frame 130. A plurality of depth cameras 200 are mounted and fixed on the mounting frame 130, the first rotating platform 121 is mounted on the translation bracket 110, the second rotating platform 122 is mounted on the first rotating platform 121, and the mounting frame 130 is mounted on the second rotating platform 122.

[0047] The translation bracket 110 can move along the X-axis and the Y-axis, and is used to drive the mounting bracket 130 to move along the X-axis to adjust the position of the depth camera 200 along the X-axis, and drive the mounting bracket 130 to move along the Y-axis to adjust the position of the depth camera 200 along the Y-axis.

[0048] The first rotating platform 121 can rotate along the Y axis to drive the mounting frame 130 to rotate along the Y axis to adjust the rotation angle of the depth camera 200 along the Y axis. The second rotating platform 122 can rotate along the X axis to drive the mounting frame 130 to rotate along the X axis to adjust the rotation angle of the depth camera 200 along the X axis. The mounting frame 130 can rotate along the Z axis to adjust the rotation angle of the depth camera 200 along the Z axis.

[0049] For example, Figure 2 As shown, the translation bracket 110 includes a first translation platform 111, and the safety camera adjustment device 100 also includes a mounting plate 140, a beam 150 and a first adjustment screw 161. Among them, the beam 150 is fixed on the mounting plate 140, the beam 150 extends along the Y axis, and the plane where the mounting plate 140 is located is parallel to the XZ plane. The first translation platform 111 is installed on the beam 150, and the plane where the first translation platform 111 is located is parallel to the XY plane.

[0050] The first mounting surface 210 of the first translation platform 111 is provided with a first threaded through hole 211, and the first adjusting screw 161 passes through the first threaded through hole 211. The first mounting surface 210 is a surface of the first translation platform 111 which is farther from the mounting plate 140 from the two side surfaces in the XZ plane.

[0051] like Figure 2 As shown, the plane where the first mounting surface 210 is located is parallel to the XZ plane, and the first threaded through hole 211 is parallel to the XZ plane. Since the first adjusting screw 161 passes through the first threaded through hole 211, the first adjusting screw 161 extends along the Y axis.

[0052] The thread in the first threaded through hole 211 can be screwed with the first adjusting screw 161. By rotating the first adjusting screw 161, the first threaded through hole 211 can be adjusted to move along the Y axis, that is, the first translation platform 111 moves along the Y axis. The movement of the first translation platform 111 along the Y axis can drive the mounting frame 130 to move along the Y axis. Since the depth camera 200 is fixed on the mounting frame 130, the first translation platform 111 can drive the depth camera 200 to move along the Y axis.

[0053] In this way, the first adjusting screw 161 can control the first translation platform 111 to move along the Y-axis to drive the depth camera 200 to move along the Y-axis, thereby adjusting the position of the depth camera 200 along the Y-axis.

[0054] For example, see Figure 2 The translation bracket 110 further includes a second translation platform 112 , and the safety camera adjustment device 100 further includes a second adjustment screw 162 . The plane where the second translation platform 112 is located is parallel to the XY plane, and the second translation platform 112 is installed on the first translation platform 111 .

[0055] A second threaded through hole 221 is provided on the second mounting surface 220 of the second translation platform 112, and the second adjusting screw 162 passes through the second threaded through hole 221. The second mounting surface 220 is any one of the two side surfaces of the second translation platform 112 in the YZ plane.

[0056] like Figure 2 As shown, the plane where the second mounting surface 220 is located is parallel to the YZ plane, and the second threaded through hole 221 is parallel to the XZ plane. Since the second adjusting screw 162 passes through the second threaded through hole 221, the second adjusting screw 162 extends along the X axis.

[0057] The thread in the second threaded through hole 221 can be screwed with the second adjusting screw 162. By rotating the second adjusting screw 162, the second threaded through hole 221 can be adjusted to move along the X-axis, that is, the second translation platform 112 moves along the X-axis. The movement of the second translation platform 112 along the X-axis can drive the mounting bracket 130 to move along the X-axis, thereby driving the depth camera 200 to move along the X-axis.

[0058] In this way, the second adjusting screw 162 can control the second translation platform 112 to move along the X-axis to drive the depth camera 200 to move along the X-axis, thereby adjusting the position of the depth camera 200 along the X-axis.

[0059] For example, see Figure 2 , the safety camera adjustment device 100 also includes a first wedge-shaped adjustment block 171 and an auxiliary platform 180. The auxiliary platform 180 is fixed on the translation bracket 110, and the first side 181 of the auxiliary platform 180 is movably connected to the first side 231 of the first rotating platform 121. The first wedge-shaped adjustment block 171 is installed between the first rotating platform 121 and the auxiliary platform 180, and passes through the area directly facing the second side 232 of the first rotating platform 121. Among them, the first side 181, 231 and the second side 232 are all parallel to the Y axis.

[0060] like Figure 2 As shown, the auxiliary platform 180 is fixed on the second translation platform 112. Two protrusions are provided on the side surface of the auxiliary platform 180 close to the first rotating platform 121. The two protrusions are located in the area close to the first side edge 181, and a mounting hole is provided on the surface facing the two protrusions. A protrusion is provided at each end of the side where the first side edge 231 of the first rotating platform 121 is located. The side where the first side edge 231 is located is parallel to the YZ plane, and a mounting column is provided on the surface facing the two protrusions. The two mounting columns are inserted into the corresponding mounting holes so that the first side edge 181 of the auxiliary platform 180 is movably connected with the first side edge 231 of the first rotating platform 121.

[0061] The first wedge-shaped adjustment block 171 passes through the area directly opposite to the second side edge 232 of the first rotating platform 121, and abuts against the auxiliary platform 180 and the first rotating platform 121. The first wedge-shaped adjustment block 171 can move along the X-axis, and the closer the first wedge-shaped adjustment block 171 is to the first side edges 181 and 231, the larger the angle between the first rotating platform 121 and the auxiliary platform 180 is, that is, the larger the rotation angle of the first rotating platform 121 along the Y-axis is.

[0062] In this way, the first wedge-shaped adjustment block 171 can control the first rotating platform 121 to rotate along the Y-axis to drive the depth camera 200 to rotate along the Y-axis, thereby adjusting the rotation angle of the depth camera 200 along the Y-axis.

[0063] For example, see Figure 2 , the safety camera adjustment device 100 further includes a second wedge-shaped adjustment block 172. The third side 241 of the second rotating platform 122 is movably connected to the third side 233 of the first rotating platform 121, and the second wedge-shaped adjustment block 172 is installed between the first rotating platform 121 and the second rotating platform 122, and passes through the area directly opposite to the fourth side 242 of the second rotating platform 122. Among them, the third side 241, 233 and the fourth side 242 are all parallel to the X-axis.

[0064] like Figure 2 As shown, two protrusions are provided on the surface of one side of the first rotating platform 121 close to the second rotating platform 122. The two protrusions are located in the area close to the third side 233, and a mounting hole is provided on the surface facing the two protrusions. A protrusion is provided at each end of the side where the third side 241 of the second rotating platform 122 is located. The side where the third side 241 is located is parallel to the XZ plane, and a mounting column is provided on the surface facing the two protrusions. The two mounting columns are inserted into the corresponding mounting holes so that the third side 241 of the second rotating platform 122 is movably connected to the third side 233 of the first rotating platform 121.

[0065] The second wedge-shaped adjustment block 172 passes through the area directly opposite to the fourth side 242 of the second rotating platform 122, and abuts against the second rotating platform 122 and the first rotating platform 121. The second wedge-shaped adjustment block 172 can move along the Y-axis, and the closer the second wedge-shaped adjustment block 172 is to the third side 233, 241, the larger the angle between the second rotating platform 122 and the first rotating platform 121, that is, the larger the rotation angle of the second rotating platform 122 along the X-axis.

[0066] In this way, the second wedge-shaped adjustment block 172 can control the second rotating platform 122 to rotate along the X-axis to drive the depth camera 200 to rotate along the X-axis, thereby adjusting the rotation angle of the depth camera 200 along the X-axis.

[0067] For example, see Figure 2 The second rotating platform 122 includes a rotating column, which is located on a side surface of the second rotating platform 122 close to the mounting frame 130. The mounting frame 130 is provided with a rotating hole, in which the rotating column is installed, and the rotating column can rotate along the Z axis in the rotating hole.

[0068] like Figure 2 As shown, the rotating column extends along the Z axis, and the mounting bracket 130 can rotate with the rotating column as the axis, thereby driving the depth camera 200 to rotate with the rotating column as the axis to adjust the rotation angle of the depth camera 200 along the Z axis.

[0069] In the disclosed embodiment, the safety camera adjustment device includes a translation bracket, a first rotating platform, a second rotating platform and a mounting frame, a plurality of depth cameras are mounted and fixed on the mounting frame, the first rotating platform is mounted on the translation bracket, the second rotating platform is mounted on the first rotating platform, the mounting frame is mounted on the second rotating platform, the translation bracket can move along the X-axis and the Y-axis, thereby driving the mounting frame to move along the X-axis to adjust the position of the depth camera along the X-axis, driving the mounting frame to move along the Y-axis to adjust the position of the depth camera along the Y-axis, the first rotating platform can rotate along the Y-axis, thereby driving the mounting frame to rotate along the Y-axis to adjust the rotation angle of the depth camera along the Y-axis, the second rotating platform can rotate along the X-axis, thereby driving the mounting frame to rotate along the X-axis to adjust the rotation angle of the depth camera along the X-axis, and the mounting frame can rotate along the Z-axis to adjust the rotation angle of the depth camera along the Z-axis. In this way, the safety camera adjustment device can adjust the position and angle of the depth camera, thereby ensuring the accuracy of the scanned image.

[0070] In some embodiments, see Figure 2 , the safety camera adjustment device 100 also includes a first support column 191, a second support column 192 and an auxiliary platform 180. The auxiliary platform 180 is fixed to the translation bracket 110, and the first side 181 of the auxiliary platform 180 is movably connected to the first side 231 of the first rotating platform 121. The first support column 191 and the second support column 192 are arranged between the first rotating platform 121 and the auxiliary platform 180 and are located at both ends of the second side 232 of the first rotating platform 121. Among them, the first side 181, 231 and the second side 232 are parallel to the Y axis.

[0071] For example, Figure 2 As shown, the auxiliary platform 180 is fixed on the second translation platform 112. Two protrusions are provided on the side surface of the auxiliary platform 180 close to the first rotating platform 121. The two protrusions are located in the area close to the first side edge 181, and a mounting hole is provided on the surface facing the two protrusions. A protrusion is provided at each end of the side where the first side edge 231 of the first rotating platform 121 is located. The side where the first side edge 231 is located is parallel to the YZ plane, and a mounting column is provided on the surface facing the two protrusions. The two mounting columns are inserted into the corresponding mounting holes so that the first side edge 181 of the auxiliary platform 180 is movably connected with the first side edge 231 of the first rotating platform 121.

[0072] A first support column 191 is disposed at one end of the second side 232 of the first rotating platform 121, and a second support column 192 is disposed at the other end of the second side 232 of the first rotating platform 121. The heights of the first support column 191 and the second support column 192 are adjustable. The higher the heights of the first support column 191 and the second support column 192, the greater the angle between the first rotating platform 121 and the auxiliary platform 180, that is, the greater the rotation angle of the first rotating platform 121 along the Y axis.

[0073] In this way, the first support column 191 and the second support column 192 can cooperate to control the first rotating platform 121 to rotate along the Y axis, so as to drive the depth camera 200 to rotate along the Y axis, thereby adjusting the rotation angle of the depth camera 200 along the Y axis.

[0074] In some embodiments, see Figure 2 , the safety camera adjustment device 100 further includes a third support column 193 and a fourth support column 194. The third side 241 of the second rotating platform 122 is movably connected to the third side 233 of the first rotating platform 121, and the third support column 193 and the fourth support column 194 are disposed between the first rotating platform 121 and the second rotating platform 122 and are located at both ends of the fourth side 242 of the second rotating platform 122. Among them, the third side 241, 233 and the fourth side 242 are all parallel to the X-axis.

[0075] For example, Figure 2 As shown, two protrusions are provided on the surface of one side of the first rotating platform 121 close to the second rotating platform 122. The two protrusions are located in the area close to the third side 233, and a mounting hole is provided on the surface facing the two protrusions. A protrusion is provided at each end of the side where the third side 241 of the second rotating platform 122 is located. The side where the third side 241 is located is parallel to the XZ plane, and a mounting column is provided on the surface facing the two protrusions. The two mounting columns are inserted into the corresponding mounting holes so that the third side 241 of the second rotating platform 122 is movably connected to the third side 233 of the first rotating platform 121.

[0076] A third support column 193 is disposed at one end of the fourth side 242 of the second rotating platform 122, and a fourth support column 194 is disposed at the other end of the fourth side 242 of the second rotating platform 122. The heights of the third support column 193 and the fourth support column 194 are adjustable. The higher the heights of the third support column 193 and the fourth support column 194, the greater the angle between the second rotating platform 122 and the first rotating platform 121, that is, the greater the rotation angle of the second rotating platform 122 along the X-axis.

[0077] In this way, the third support column 193 and the fourth support column 194 cooperate to control the second rotating platform 122 to rotate along the X-axis, so as to drive the depth camera 200 to rotate along the X-axis, thereby adjusting the rotation angle of the depth camera 200 along the X-axis.

[0078] In some embodiments, the safety camera adjustment device 100 further includes a plurality of fixing members. The plurality of fixing members are used to fix the depth camera 200 after adjusting the position along the Y axis, the position along the X axis, the rotation angle along the Y axis, the rotation angle along the X axis, and the rotation angle along the Z axis of the depth camera 200.

[0079] Exemplarily, after adjusting the position of the depth camera 200 along the Y axis, the fixing member may fix the first translation platform 111 on the beam 150. After adjusting the position of the depth camera 200 along the X axis, the fixing member may fix the second translation platform 112 on the first translation platform 111. After adjusting the rotation angle of the depth camera 200 along the Y axis, the fixing member may fix the first rotating platform 121 on the auxiliary platform 180. After adjusting the rotation angle of the depth camera 200 along the X axis, the fixing member may fix the second rotating platform 122 on the first rotating platform 121. After adjusting the rotation angle of the depth camera 200 along the Z axis, the fixing member may fix the mounting frame 130 on the second rotating platform 122.

[0080] In some embodiments, Figure 2 As shown, the safety camera assembly 10 further includes a plurality of calibration light sources 300 . The calibration light sources 300 are fixed on the mounting bracket 130 , and are used to calibrate the position and angle of the depth camera 200 .

[0081] For example, Figure 2 As shown, the safety camera assembly 10 includes three calibration light sources 300 . The plurality of calibration light sources 300 cooperate with the plurality of calibration marks to calibrate the position and angle of the depth camera 200 .

[0082] In other embodiments, the safety camera assembly 10 may further include two calibration light sources 300 , four calibration light sources 300 , or more than four calibration light sources 300 . The present disclosure does not specifically limit the number of calibration light sources 300 in the safety camera assembly 10 .

[0083] The calibration light source 300 may emit a calibration beam, and each calibration beam emitted by the calibration light source 300 is irradiated onto the calibration reticle. When the center of at least one calibration beam does not match the center of the calibration reticle, at least one of the position of the depth camera 200 along the X-axis, the position along the Y-axis, the rotation angle along the X-axis, the rotation angle along the Y-axis, and the rotation angle along the Z-axis may be adjusted, so that the relative positions of the centers of all calibration beams and the centers of the corresponding calibration reticle may be adjusted.

[0084] When the center of each camera calibration beam is adjusted to match the center of a calibration mark, stop adjusting the position of the depth camera 200 along the X-axis, the position along the Y-axis, the rotation angle along the X-axis, the rotation angle along the Y-axis, and the rotation angle along the Z-axis, thereby completing the calibration of the position and angle of the depth camera 200.
