[0028] It can be understood that in the above technical solution, the utility model adjusts the installation position of the phantom positioning plate 9 in the three directions of XYZ through the multi-degree-of-freedom installation component, and can also adjust the installation angle of the phantom positioning plate 9 centered on the Z axis, so that the relative position between the phantom and the ultrasonic transducer in the actual space can be accurately known, so that the difference between the imaging distance and the actual placement position can be more accurately determined after imaging, and the position offset relative to the ultrasonic transducer in the three directions of XYZ can also be accurately compared and the effect evaluated.

[0029] Continue reading Figure 1 and Figure 2 The multi-degree-of-freedom mounting assembly includes a Z-axis angle adjustment mechanism, an X-axis position adjustment mechanism, a Y-axis position adjustment mechanism and a Z-axis position adjustment mechanism. The Y-axis position adjustment mechanism is slidably mounted on the X-axis position adjustment mechanism along the X-axis direction, the Z-axis position adjustment mechanism is slidably mounted on the Y-axis position adjustment mechanism along the Y-axis direction, the Z-axis angle adjustment mechanism is slidably mounted on the Z-axis position adjustment mechanism along the Z-axis direction, and the phantom positioning plate 9 is arranged on the Z-axis angle adjustment mechanism.

[0030] Further reading Figure 1 and Figure 2 The X-axis position adjustment mechanism includes an X-axis mounting seat 1 and two left and right X-axis moving platforms 3 laid on the X-axis mounting seat 1 along the X-axis direction, and the Y-axis position adjustment mechanism is slidably installed on the two X-axis moving platforms 3 along the X-axis direction.

[0031] Further reading Figure 1 and Figure 2 The Y-axis position adjustment mechanism includes a Y-axis mounting seat 4 and a Y-axis movable platform 2 laid on the Y-axis mounting seat 4 along the Y-axis direction, and the Z-axis position adjustment mechanism is slidably installed on the Y-axis movable platform 2 along the Y-axis direction.

[0032] Further reading Figure 1 and Figure 2 The Z-axis position adjustment mechanism includes a Z-axis mounting seat 5 and a Z-axis movable platform 6 laid on the Z-axis mounting seat 5 along the Z-axis direction, and the Z-axis angle adjustment mechanism is slidably mounted on the Z-axis movable platform 6 along the Z-axis direction.

[0033] Further reading Figure 1-Figure 4 The Z-axis angle adjustment mechanism includes a Z-axis fixing seat 7 and a direction positioning block 8. The Z-axis fixing seat 7 is slidably installed on the Z-axis moving platform 6 along the Z-axis direction. The direction positioning block 8 is detachably connected to the Z-axis fixing seat 7. The connecting rod of the phantom positioning plate 9 is connected to the direction positioning block 8 by a bolt 10 arranged along the Z-axis direction. Loosening the bolt 10 can adjust the installation angle of the phantom positioning plate 9 on the direction positioning block 8 with the Z-axis as the center.

[0034] The cross section of the direction positioning block 8 is square (without considering the rounded corners), and its cross-sectional area gradually decreases from top to bottom. It has conical surfaces all around, and is plugged into the conical hole of the Z-axis fixing seat 7. The conical hole matches the shape and size of the direction positioning block 8, and the two are positioned through the conical surface. The direction positioning block 8 can still cooperate with the conical hole of the Z-axis fixing seat 7 every 90° rotation, and the angle of the phantom can be changed by rotating the direction positioning block 8. The direction positioning block 8 is clamped between the connecting rod of the phantom positioning plate 9 and the head of the bolt 10. After loosening the bolt 10, the connecting rod can be rotated to adjust the installation angle of the phantom positioning plate 9.

[0035] It should be noted that the above-mentioned X-axis moving platform 3, Y-axis moving platform 2 and Z-axis moving platform 6 are all manual slide rails with knobs. The knobs are screwed on the sliders of the manual slide rails and are used to clamp the slide rails. When the knobs are loosened, the sliders can move on the slide rails. This is a well-known technology and will not be elaborated on.

[0036] Continue reading Figure 1 and Figure 2The positioning mechanism is arranged on the X-axis mounting seat 1, and the positioning mechanism includes a positioning ring 11 and two lifting components. The positioning ring 11 is provided with a positioning pin 15. The positioning ring 11 and the positioning pin 15 are used to position and connect with the ultrasonic transducer device. The lifting components are arranged on both sides of the positioning ring 11, and include a slide bar 12, two support members 13 and a hanging seat 14. The hanging seat 14 is located on the upper surface of the X-axis mounting seat 1. The slide bar 12 is slidably installed on the X-axis mounting seat 1 along the Z-axis direction. It can rotate on the X-axis mounting seat 1 with the Z-axis as the center. Its upper and lower ends are respectively connected with the hanging seat 14 and the positioning ring 11. The two support members 13 are respectively located on both sides of the slide bar 12. The support member 13 is a vertically arranged rod, which is used to block with the upper surface of the multi-degree-of-freedom mounting assembly.

[0037] The positioning mechanism has a first height position and a second height position arranged vertically. When the positioning mechanism is at the first height position, the support member 13 is in contact with the upper surface of the X-axis mounting seat 1, and the mounting seat 14 is suspended on the X-axis mounting seat 1 and does not contact the X-axis mounting seat 1. After the positioning mechanism is rotated 90°, the support member 13 is staggered from the X-axis mounting seat 1, and it does not contact the upper surface of the multi-degree-of-freedom mounting assembly. At this time, the positioning mechanism can be moved down to the second height position so that the mounting seat 14 is supported on the upper surface of the X-axis mounting seat 1.

[0038] Among them, a non-through blind hole 100 and a through hole 101 are opened on the X-axis mounting seat 1. When the positioning mechanism is at a first height position, the support member 13 is inserted into the blind hole 100. When the positioning mechanism is rotated 90° and is at a second height position, one support member 13 is inserted into the through hole 101, and the other support member 13 avoids the X-axis mounting seat 1.

[0039] During use, the operator installs and fixes the phantom on the phantom fixing plate 9, which is connected to the direction positioning block 7, and then places the direction positioning block 7 on the Z-axis fixing seat 6. The direction positioning block 7 and the Z-axis fixing seat 6 each have a 20° cone surface that can cooperate with each other. After being placed together, they can be stably and accurately coordinated with each other for positioning. The direction positioning block 7 can rotate around the Z axis, thereby driving the phantom to rotate. The operator can adjust the distance position of the phantom in the X and Y axis directions through the knobs on the Y-axis moving platform 2 and the X-axis moving platform 3, thereby achieving precise movement and positioning of the phantom in the X and Y axis directions. The user can adjust the height of the phantom in the Z axis direction through the knob on the Z-axis moving platform 6, thereby achieving precise movement and positioning of the phantom in the Z axis direction.

[0040] The fixation between the utility model and the ultrasonic transducer device is achieved through the positioning ring 11 and the positioning pin 15. The positioning ring 11 is placed in the metal ring on the ultrasonic transducer device, and then the positioning pin 15 is inserted into the positioning pin hole on the ultrasonic transducer device, so that the fixation between the ultrasonic test positioning device and the ultrasonic transducer device can be achieved. The lifting and lowering of the positioning ring 11 is achieved by the lifting assembly of the positioning ring 11. During operation, hold the hanging seats 14 on both sides with both hands at the same time, rotate them 90°, and let the four supporting members 13 avoid the X-axis mounting seat 1. At this time, the positioning ring 11 can be put down. To lift the positioning ring 11, perform the same operation, hold the hanging seats 14 on both sides with both hands at the same time, and after lifting the positioning ring 11, rotate the hanging seats 14 90°, so that the four supporting members 13 are supported on the X-axis mounting seat 1. In this way, the rise and fall of the positioning ring 11 are completed.

[0041] The utility model is quick and convenient to use, can accurately locate and quantitatively measure the displacement, and is convenient for comparison and evaluation of position data after body model imaging.
