Description

Technical Field

[0001] The present application relates to the field of radiotherapy auxiliary devices, and in particular to a laser line calibration phantom. Background Art

[0002] Radiotherapy is a treatment method that irradiates the patient with radiation, allowing the radiation to penetrate the patient's skin and destroy the lesions in the patient's body. By having the patient lie on the treatment bed and irradiating the laser beam light at different positions on the patient's body, it can have a therapeutic effect on a variety of diseases.

[0003] The relevant laser line light can be installed on the side or top of the treatment bed. The laser line light irradiates radiation horizontally or vertically so that the radiation falls on the patient's lesion on the treatment bed, thereby achieving the treatment purpose.

[0004] The above-mentioned related technical solutions have the following defects: the laser line light fixed in the ward is prone to loosening at the connection after a long period of use, which makes it difficult for the laser line light to accurately illuminate the patient's lesion. The calibration of the landing point of the laser line light is done manually, which is inefficient and time-consuming. Utility Model Content

[0005] In order to improve the calibration efficiency of laser line lights, the present application provides a laser line calibration phantom.

[0006] The laser line calibration phantom provided in this application adopts the following technical solution:

[0007] A laser line calibration mold body comprises a module, a column and a side plate. The module is a cubic structure. A plurality of columns are arranged. The plurality of columns are fixed on the lower bottom surface of the module. The columns are supported on the ground. When the module is fixed on the ground by the columns, the upper surface of the module is arranged horizontally. A hollow groove one is opened on the module. The hollow groove one is horizontally opened on the side surface of the module and penetrates the module. The side plates are arranged on the side edges of the module, and there is a gap between the side plates and the module.

[0008] By adopting the above technical solution, by opening a hollow groove one on the module, the operator can make the laser line light illuminate the module and make the light enter the hollow groove one. When the irradiation direction of the light is parallel to the length direction of the hollow groove one, the light can be irradiated on the side panel and leave a light spot. When there is an angle between the irradiation direction of the light and the length direction of the hollow groove one, the light is irradiated on the inner wall of the hollow groove one, and no light spot is generated on the side panel. The operator can detect that there is a deviation between the direction of the laser line light and the predetermined direction, which makes it convenient for the operator to adjust the direction of the laser line light. The operator adjusts the direction of the laser line light until a light spot is generated on the side panel, indicating that the direction of the laser line light is adjusted to be parallel to the length direction of the hollow groove one on the relative module, which can improve the efficiency of calibrating the laser line light.

[0009] Optionally, a bottom plate is provided on the column, and when the module is set on the ground, the bottom plate is set horizontally, and a hollow groove three is opened on the module, and the hollow groove three is opened vertically and passes through the module.

[0010] By adopting the above technical solution, by setting a base plate on the column, so that the base plate is set below the module, the operator can make the laser line light shine vertically downward, and then make the light shine in the hollow groove three. When the direction of the laser line light is parallel to the hollow groove three, a light spot is generated on the base plate. The operator can quickly adjust the laser line light according to the position of the light spot on the base plate, so that the laser line light can shine vertically downward on the patient's lesion.

[0011] Optionally, a side scale groove is opened on the surface of one side of the side plate close to the module, and the side scale groove coincides with the first position of the hollow groove. A bottom scale groove is opened on the surface of one side of the bottom plate close to the module, and the bottom scale groove coincides with the third position of the hollow groove.

[0012] By adopting the above technical solution, a side scale groove is opened on the side panel so that the position of the side scale groove coincides with the position of the hollow groove one. When the light spot enters the hollow groove one and shines on the side panel, the operator can observe whether the position of the light spot is located in the side scale groove, thereby facilitating the operator to check the position offset of the laser line light and improving the calibration accuracy.

[0013] Optionally, the first hollow groove and the third hollow groove intersect at one point.

[0014] By adopting the above technical solution, by interconnecting multiple hollow grooves, the operator can set the module at the treatment bed placement position and calibrate the laser line lights installed at different positions on the treatment bed side, so that multiple laser line lights can perform radiotherapy on the same lesion of the patient at the same time, thereby improving the position accuracy of multiple laser line lights.

[0015] Optionally, the hollow groove includes two transverse grooves, the two transverse grooves are perpendicular to each other and connected, and the hollow groove is a cross-shaped groove.

[0016] By adopting the above technical solution, by making the two horizontal grooves perpendicular to each other to form a hollow groove, the operator can aim the light at the cross center of the hollow groove and shine it into the hollow groove. By observing the position of the light spot on the side scale groove, the offset direction of the laser line light can be judged. The operator can quickly find the angle that needs to be adjusted, thereby further improving the calibration efficiency.

[0017] Optionally, a foot support is provided on one end of the column away from the module, and the foot support is provided below the base plate, and is used for supporting the treatment bed surface.

[0018] By adopting the above technical solution, by arranging a foot support on the column, the foot support is supported on the treatment bed, so that there is a gap between the bottom plate and the treatment bed, which can reduce the probability of friction and collision between the bottom plate and the treatment bed, and reduce the probability of the bottom plate tilting.

[0019] Optionally, the foot support is configured as a telescopic rod, the telescopic rod includes a sleeve and a support rod, an internal thread is provided in the sleeve, a thread is provided on the support rod, the support rod and the sleeve are threadedly connected, and the telescopic rod is used to extend and retract and adjust the module to a horizontal state.

[0020] By adopting the above technical solution and arranging telescopic rods on the foot support, the operator can adjust the lengths of the multiple telescopic rods so that the module can maintain a horizontal state on an uneven ground.

[0021] In summary, the beneficial technical effects of this application are:

[0022] 1. By opening multiple hollow slots on the module, the operator can align the laser line light with the hollow slots to allow the light to pass through the hollow slots and shine on the side panels. When the light emission direction is parallel to the hollow slots, the light can shine on the side panels and form light spots. The operator can adjust the direction of the laser line light according to the light spots on the side panels, thereby improving the calibration efficiency.

[0023] 2. By opening a side scale line on the side panel, when the light enters the hollow groove, the light can shine on the side panel. The operator shoots the light from the cross center of the hollow groove. When the light emission direction is parallel to the hollow groove, the light shines on the center of the side scale groove. The operator can determine the adjustment angle of the laser line light by checking the position of the light spot relative to the center of the side scale groove;

[0024] 3. By setting telescopic rods on the foot support, the operator can adjust the length of multiple telescopic rods to keep the module level on uneven ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] The present application embodiment discloses a laser line calibration phantom, referring to Figure 1 and Figure 2, including a module 1, a plurality of columns 2 and a side panel 3. The module 1 is a cubic structure. The plurality of columns 2 are fixed on the surface of one side of the module 1. The columns 2 are supported on the ground so that the module 1 can be fixed on the ground. When the module 1 is fixed on the ground, the upper surface of the module 1 is set horizontally. The side panel 3 is detachably connected to one side of the module 1. A plurality of connecting rods 31 are fixed on the side panel 3. The end of the connecting rod 31 away from the side panel 3 is detachably connected to the surface of the module 1. The side panel 3 is parallel to the surface of the module 1 close to the side panel 3. A hollow groove 11 is provided on the module 1. The hollow groove 11 includes two transverse grooves. The two transverse grooves are perpendicular to each other and connected. The transverse groove runs through the module 1. The length direction of the transverse groove is perpendicular to the surface of the module 1 where the transverse groove is provided. When light enters the hollow groove 11 parallel to the hollow groove 11, the light can be irradiated on the side panel 3. A side scale groove 32 is provided on the surface of the side plate 3 near the module 1. The side scale groove 32 is a cross-shaped groove, and the cross center of the side scale groove 32 coincides with the cross center of the hollow groove 11. When the light enters the hollow groove 11 parallel to the hollow groove 11, the light can be irradiated on the side plate 3 and located in the side scale groove 32. When the light extension direction is not parallel to the length direction of the hollow groove 11, the optical fiber irradiates the inner wall of the hollow groove 11 during the process of advancing in the module 1, and no light spot is generated on the side plate 3. Therefore, the operator can adjust the direction of the laser light according to the light spot on the side plate 3 until a light spot is generated on the side plate 3 and located in the side scale groove 32.

[0030] Reference Figure 1 and Figure 2 , the module 1 is provided with a hollow groove 2 12 and a hollow groove 3 13, the length directions of the hollow groove 1 11, the hollow groove 2 12 and the hollow groove 3 13 are perpendicular to each other, and the cross centers of the hollow groove 1 11, the hollow groove 2 12 and the hollow groove 3 13 intersect at one point. A bottom plate 4 is provided at the bottom of the module 1, the bottom plate 4 is fixed on the column 2, and the bottom plate 4 is parallel to the surface of the module 1 close to the bottom plate 4. A bottom scale groove 41 is provided on the bottom plate 4, and the bottom scale groove 41 is a cross groove, and the cross center of the bottom scale groove 41 coincides with the cross center of the hollow groove 3 13. When the light enters the hollow groove 3 13 vertically, the light can be irradiated on the bottom plate 4 and fall into the bottom scale groove 41. The operator can set the module 1 below the laser line light, so that the module 1 can detect the direction of the vertically oriented laser line light. When a patient needs to use multiple laser line lights to irradiate the same lesion, the operator can use module 1 to detect whether the directions of the multiple laser line lights are aligned.

[0031] Reference Figure 1 and Figure 2 The surface of the side plate 3 and the bottom plate 4 is coated with radioactive luminescent paint. When the radiation used for radiotherapy is irradiated on the side plate 3 and the bottom plate 4, the position where the radiation is irradiated on the side plate 3 and the bottom plate 4 will emit light, making it convenient for the operator to find the landing point of the radiation.

[0032] Reference Figure 1 A foot support 5 is provided at the bottom of the column 2, and the foot support 5 is located at the bottom of the base plate 4. The foot support 5 is used to abut against the ground and support the module 1, thereby reducing the friction between the base plate 4 and the ground, so that the base plate 4 can remain level.

[0033] Reference Figure 1 A through hole is provided on the side surface of the module 1, and the connecting rod 31 is inserted into the through hole. In other embodiments, the module 1 and the connecting rod 31 are connected magnetically, and the operator can install the side panel 3 on different sides of the module 1 by inserting the connecting rod 31 into the through holes on different surfaces of the module 1.

[0034] In other embodiments, the foot support 5 is provided with universal wheels, and the operator can push the module 1 to slide on the ground through the universal wheels, which further facilitates the operator to adjust the position of the module 1 on one side of the laser line light.
