[0057] The utility model discloses a mobile laser positioning system calibration model, and one model can realize the debugging of laser lights in three directions, thus simplifying the debugging process, improving the debugging efficiency, and simplifying the calibration process.

[0058] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] See also Figures 2 to 11 The mobile laser positioning system calibration phantom of the utility model comprises a bottom plate 9, a front end plate 2, a rear end plate 7, a left side plate 1, a right side plate 6 and a top plate 3 connected to form a box structure, and the box structure is a cavity structure. The top plate 3 is provided with a first opening 302, a first top mark line and a second top mark line, and the first top mark line and the second top mark line are arranged to intersect vertically. The bottom plate 9 is provided with a first bottom mark line and a second bottom mark line, and the first top mark line is arranged opposite to the first bottom mark line, and the second top mark line is arranged opposite to the second bottom mark line. The first opening 302 is connected to the inner cavity of the box structure, so that the first bottom mark line and the second bottom mark line on the bottom plate 9 can be seen through the first opening 302, so that it can be judged whether the light that coincides with the mark line on the top plate 3 coincides with the mark line on the bottom plate 9 after a distance, so as to judge whether the light emitted by the sagittal plane indicator light is vertical. The first top mark line and the second top mark line intersect at the center of the top plate 3.

[0060] Among them, the first plate body 101 of the left side plate 1 is provided with a first left engraved line 104 and a second left engraved line 102 arranged to intersect vertically, and the right side plate 6 is provided with a first right engraved line 604 and a second right engraved line 602 arranged to intersect. The first left engraved line 104 is arranged correspondingly to the first right engraved line 604, the second left engraved line 102 is arranged correspondingly to the second right engraved line 602, the second left engraved line 102 intersects with the second top marking line, and the surface where the two are located is arranged vertically with the first left engraved line 104, so as to facilitate the inspection of whether the light emitted by the vertically intersecting coronal plane indicator light and the cross-section indicator light is vertical. The second top marking line intersects with the second left engraved line 102. By setting the second top marking line and the second bottom marking line, it is convenient to verify whether the light of the cross-section indicator light located above the side is vertical. When the cross-section indicator light is located above the side, it is inconvenient to check using the left side plate 1 and the right side plate 6.

[0061] The first left scale line 104 is set corresponding to the first right scale line 604, the left coronal plane indicator light is aligned with the first left scale line 104, and the right coronal plane indicator light is aligned with the first right scale line 604. The two indicator lights are simultaneously displaced in the same direction by a set distance. The scales on the corresponding scale lines are used to determine whether the left coronal plane indicator light and the right coronal plane indicator light are moving synchronously and the accuracy of the movement in place. At the same time, in order to determine whether the light of the left coronal plane indicator light is vertical, it is determined whether the light of the left coronal plane indicator light aligned with the first left scale line 104 coincides with the set reference marking line after a certain distance. This reference marking line is set corresponding to the first left scale line 104. If the light of the light does not coincide with the reference marking line after a certain distance, then the left coronal plane indicator light is tilted, and the angle of the left coronal plane indicator light is adjusted until the light of the left coronal plane indicator light can pass through the first left scale line 104 and the reference marking line at the same time. Similarly, the verticality of the right coronal plane indicator light is adjusted. The right coronal plane indicator light and the left coronal plane indicator light are set relatively synchronously.

[0062] The second left scale line 102 is set correspondingly to the second right scale line 602, the left cross-section indicator light is aligned with the second left scale line 102 of the model, and the right cross-section indicator light is aligned with the second right scale line 602 of the model. The two indicator lights are simultaneously displaced in the same direction by a set distance. The scales on the corresponding scale lines are used to determine whether the left coronal plane indicator light and the right coronal plane indicator light move synchronously and the accuracy of the movement. At the same time, in order to determine whether the light of the left cross-section indicator light is vertical, it is determined whether the light of the left cross-section indicator light aligned with the second left scale line 102 coincides with the set reference mark line after a distance. This reference mark line is set correspondingly to the second left scale line 102. If the light does not coincide with the reference mark line after a distance, then the left cross-section indicator light is tilted, and the angle of the left cross-section indicator light is adjusted until the light of the left cross-section indicator light can pass through the second left scale line 102 and the reference mark line at the same time. Similarly, the verticality of the right cross-section indicator light is adjusted. The right cross-section indicator light and the left cross-section indicator light are set relatively synchronously. The second left score line 102 and the second right score line 602 can serve as reference marking lines to each other, and the first left score line 104 and the first right score line 604 can serve as reference marking lines to each other.

[0063] The mobile laser positioning system calibration model of the utility model is provided with a top plate 3 and a bottom plate 9, and a first opening 302, a first top mark line and a second top mark line are provided on the second plate body 303 of the top plate 3, and a first bottom mark line and a second bottom mark line are provided on the bottom plate 9, so as to facilitate the judgment of whether the sagittal plane indicator light is deflected or tilted, and the sagittal plane indicator light is vertically aligned by adjusting the angle of the sagittal plane indicator light. The left side plate 1 is provided with a first left engraved line 104 and a second left engraved line 102 which are vertically intersected, and the right side plate 6 includes a main body 601, and the main body 601 is provided with a first right engraved line 604 and a second right engraved line 602 which are intersected, and the first left engraved line 104 and the first right engraved line 604 are provided in cooperation to detect whether the left and right coronal plane indicator lights are aligned, and whether the coronal plane indicator light is skewed is judged by whether the light of the indicator light coincides with the respective reference mark lines after passing through the first left engraved line 104 and the first right engraved line 604. The second left engraved line 102 and the second right engraved line 602 are arranged in coordination to detect whether the left and right cross-sectional indicator lights are aligned, and whether the cross-sectional indicator lights are arranged obliquely is determined by whether the light of the indicator lights coincides with the respective reference marking lines through the second left engraved line 102 and the second right engraved line 602. The mobile laser positioning system calibration phantom of the utility model completes the debugging and calibration of the accuracy and synchronization of the positions of the laser lights of each surface of the mobile laser positioning system by aligning the laser lights in the mobile laser positioning system with the corresponding marks on the phantom, thereby simplifying the debugging process, improving the debugging efficiency, providing convenience for clinicians, and greatly improving the quality and efficiency of daily quality control of the mobile laser positioning system. The calibration process is simple and the calibration efficiency is fast.

[0064] In order to facilitate setting the reference marking line, a middle partition 4 is arranged in the cavity of the box structure, and the middle partition 4 is arranged parallel to the left side plate 1. Specifically, the left side plate 1 is arranged parallel to the right side plate 6, and the bottom plate 9 is arranged parallel to the top plate 3. The length of the bottom plate 9 is greater than the length of the top plate 3. The middle partition 4 is arranged along the center line of the length direction of the bottom plate 9, such as Figure 2 As shown. Among them, the first calibration scale line 402 and the second calibration scale line 401 are arranged on the surface of the middle partition plate 4 close to the left side plate 1, the first calibration scale line 402 is arranged corresponding to the first left scale line 104, and the second calibration scale line 401 is arranged corresponding to the second left scale line 102. The above corresponding arrangement means that the distances of the two relative to the same reference surface are the same. For example, the first calibration scale line 402 and the first left scale line 104 are arranged correspondingly, which means that the heights of the two from the bottom plate 9 are the same, and the two are arranged in parallel, so that the laser light passing through the first left scale line 104 can be irradiated on the first calibration scale line 402 when it is vertically incident.

[0065] It can be understood that in order to facilitate the detection of the movement synchronization performance of the left coronal plane indicator light and the right coronal plane indicator light, the first left scale line 104 and the second left scale line 102 are both provided with uniformly distributed scale values, referring to Figure 7 and Figure 8 Similarly, the first calibration scale line 402 and the second calibration scale line 401 are also provided with uniformly distributed scale values, such as Fig.11 The third calibration scale line and the fourth calibration scale line (not shown) are arranged on the surface of the middle partition plate 4 close to the right side plate 6. The specific arrangement method thereof refers to the arrangement method of the first calibration scale line 402 and the second calibration scale line 401. The third calibration scale line is arranged parallel to the first calibration scale line 402 and opposite to each other on two opposite sides of the middle partition plate 4. The fourth calibration scale line is arranged parallel to the second calibration scale line 401 and opposite to each other on two opposite sides of the middle partition plate 4.

[0066] The first top mark line is set along the length direction of the top plate 3, and the first top mark line is used to calibrate whether the light emitted by the sagittal plane indicator light is vertical. The second top mark line is set along the width direction of the top plate 3. The first left mark line 104 is set along the length direction of the left side plate 1, and the second left mark line 102 is set along the height direction of the left side plate 1. The second left mark line 102 is set perpendicular to the second top mark line. Figure 6 The first top marking line includes a first main marking line 301 and two first side marking lines 305. The two first side marking lines 305 are symmetrically arranged on both sides of the first main marking line 301. Figure 6 The first bottom marking line includes a second main marking line 901 and two second side marking lines 902, and the two second side marking lines 902 are symmetrically arranged on both sides of the second main marking line 901. The first main marking line 301 and the second main marking line 901 are arranged correspondingly, and the two are arranged in the same vertical plane. The first side marking line 305 and the second side marking line 902 are arranged correspondingly, and the two corresponding sides are arranged in the same vertical plane. Figure 2It can be seen that since the middle partition 4 is arranged along the center line of the length direction of the bottom plate 9, that is, the middle partition 4 is arranged along the second main marking line 901, the middle partition 4 will block the part of the second main marking line 901 located in the inner cavity of the calibration phantom. If the first main marking line 301 and the second main marking line 901 are used to verify the verticality of the sagittal laser light, it is only possible to use the part of the second main marking line 901 located outside the inner cavity of the calibration phantom to determine whether the light irradiated on the first main marking line 301 can simultaneously irradiate the second main marking line 901 outside the inner cavity of the calibration phantom. Or use the first side marking line 305 and the second side marking line 902 on both sides. By setting the first side marking line 305 and the second side marking line 902, it is not only used to assist in detecting whether the light of the sagittal indicator light is vertical, but also can be used to detect whether the movement process of the sagittal indicator light to the set distance is accurate. It can be understood that the set distance here is the interval distance between the main marking line and the side marking line. In order to detect the accuracy of the sagittal plane indicator light moving at different distances, a first reference scale line 304 is provided at the edge of the wide side of the first opening 302 .

[0067] Further, the second top marking line includes a third main marking line 306 and two third side marking lines 307, and the two third side marking lines 307 are symmetrically arranged on both sides of the third main marking line 306. The second bottom marking line includes a fourth main marking line 903 and two fourth side marking lines 904, and the two fourth side marking lines 904 are symmetrically arranged on both sides of the fourth main marking line 903. The third main marking line 306 is arranged correspondingly to the fourth main marking line 903, and the third side marking line 307 is arranged correspondingly to the fourth side marking line 904. The edge of the long side of the first opening 302 is provided with a second reference scale line 308. By setting the corresponding second top marking line and the second bottom marking line, the specific calibration process refers to the first top marking line and the first bottom marking line. When the cross-section indicator light is not set on both sides of the calibration model, but is set on the upper side of the model, the second top mark line and the second bottom mark line are used to verify whether the light of the cross-section indicator light is vertical. In this case, it is inconvenient to use the left side plate 1 and the right side plate 6 to verify the light of the cross-section indicator light. At this time, the second top mark line can be used in conjunction with the second bottom mark line to verify whether the light of the cross-section indicator light is vertical. When the cross-section indicator light is aligned with the second top mark line and also aligned with the second bottom mark line, it indicates that the light of the cross-section indicator light is vertical. If the light is aligned with the second top mark line but not with the second bottom mark line, it indicates that the light of the cross-section indicator light is not vertical, and the cross-section indicator light needs to be adjusted until the light is aligned with both mark lines. It can be understood that when the light of the cross-section indicator light is aligned with the third main mark line 306, check whether the light can be irradiated on the fourth main mark line 903 at the same time. If the light can coincide with the above two lines at the same time, the light of the cross-section indicator light is vertical, otherwise, it is not vertical, and it needs to be adjusted and then checked. When the light of the cross-section indicator light is aimed at the third side marking line 307, check whether the light can shine on the fourth side marking line 904 at the same time, wherein the third side marking line 307 and the fourth side marking line 904 are calibrated on the same side. If the light can coincide with the above two lines at the same time, the light of the cross-section indicator light is vertical. Otherwise, it is not vertical and should be adjusted before calibration.

[0068] In order to correspond to the center position of the mobile laser positioning system, the first left engraved line 104 and the second left engraved line 102 intersect at the center position of the left side plate 1, and the scale values ​​of the first left engraved line 104 and the second left engraved line 102 are symmetrically arranged about the center position of the left side plate 1. Similarly, the first right engraved line 604 and the second right engraved line 602 intersect at the center position of the right side plate 6, and the scale values ​​of the first right engraved line 604 and the second right engraved line 602 are symmetrically arranged about the center position of the right side plate 6. Among them, the intersection position of the first left engraved line 104 and the second left engraved line 102 is set to 0 scale. The intersection position of the first right engraved line 604 and the second right engraved line 602 is set to 0 scale. By setting the second top mark line and the second bottom mark line, the two ends of the second left engraved line 102 are respectively connected to the two, and similarly, the two ends of the first right engraved line 604 are respectively connected to the two, so as to ensure the relative arrangement of the second left engraved line 102 and the first right engraved line 604.

In a specific embodiment, two first light holes 105 are provided, and the two first light holes 105 are respectively provided on both sides of the second left engraved line 102. The two first light holes 105 are at the same distance from the second left engraved line 102, that is, the first light holes 105 are symmetrically provided on both sides of the center position of the left side plate 1.

[0073] The calibration phantom of the mobile laser positioning system of the utility model is assembled, spliced ​​or processed as a whole. It can be understood that the material of the calibration phantom is non-metallic material, so as to be used for CT or MRI scanning.

[0074] The mobile laser positioning system calibration model of the utility model includes the following steps:

[0075] (a) Place the calibration phantom at the center of the mobile laser positioning system to make the calibration phantom level. During adjustment, adjust the level adjustment device 8 and use the level meter 5 to confirm whether the phantom is level.

[0076] (b) Align the left cross-sectional indicator light with the second left mark 102 of the calibration phantom, align the left coronal plane indicator light with the first left mark 104 of the calibration phantom, align the right cross-sectional indicator light with the second right mark 602 of the calibration phantom, align the right coronal plane indicator light with the first right mark 604 of the calibration phantom, and align the sagittal plane indicator light with the first top marking line of the phantom top plate 3. The first top marking line here can be either the first main marking line 301 or the first side marking line 305.

[0077] (c) Observe whether the left cross-sectional indicator light is aligned with the second calibration scale line 401 after passing the second left scale line 102. If not, adjust the deflection angle of the left cross-sectional indicator light so that the left cross-sectional indicator light is aligned with the second calibration scale line 401 after passing the second left scale line 102.

[0078] (d) Observe whether the sagittal plane indicator light is aligned with the first top marking line of the top plate 3.

When adjusting in one embodiment, observe whether the sagittal plane indicator light is aligned with the second main marking line 901 at the same time when it is aligned with the first main marking line 301. In order to avoid the degree of influence on the alignment due to the blocking of the middle partition 4, the part of the second main marking line 901 located at the end, that is, the part located on the outside of the cavity of the box structure, can be used. In another embodiment, when adjusting, observe whether the sagittal plane indicator light is aligned with the first side marking line 305 and the second side marking line 902 at the same time. It can be understood that when adjusting the verticality, it is necessary to use the first side marking line 305 and the second side marking line 902 located on the same side.

[0079] (e) according to step (c), the calibration of the left coronal plane, the right transverse plane, and the right coronal plane indicator lights is completed in sequence;

[0080] (f) Automatically move the cross-sectional indicator light, coronal indicator light, and sagittal indicator light. Observe whether the cross-sectional indicator light and coronal indicator light on the left and right sides are synchronized by the scale value on the corresponding side panel, and verify the accuracy of the position according to the scale value on the phantom. Automatically move the sagittal indicator light to verify the accuracy of the position according to the reference scale line.
