Description

Technical Field

[0001] The utility model relates to the field of automatic leveling devices, in particular to an automatic leveling device for an accelerator quality control phantom. Background Art

[0002] Verification of patient treatment plans is a key link in ensuring the quality and safety of radiotherapy. Transplanting the plan onto a quality control phantom for verification is a common method. When verifying the treatment plan, the quality control phantom is first placed at the isocenter position below the accelerator treatment head. Its position is adjusted by moving the treatment bed or the quality control phantom itself. Then, the quality control phantom is irradiated according to the patient's actual treatment plan, and the dose distribution and related parameters of each irradiation field are recorded. Next, the measurement results are compared and analyzed with the dose calculated in the treatment plan. By analyzing the deviation between the measurement results and the planned dose, the accuracy of the treatment plan can be determined. Transplanting the plan onto the phantom for verification can detect errors in the plan before actual treatment, thereby ensuring the safety and effectiveness of the treatment.

[0003] For example, patent number CN214762921 U discloses a multifunctional quality control phantom for radiotherapy equipment, which includes a phantom body, which is a cubic cavity with an opening, and scale lines are provided on the upper, lower, left and right surfaces of the phantom body. Solid water is provided inside the phantom body, and four height-adjustable support feet are provided on the lower side of the phantom body. A level detection device is provided on the phantom body, and multiple detection plug-ins can be detachably installed on the phantom body. The device can facilitate the adjustment and detection of the levelness of the phantom body, thereby improving the accuracy of the detection. Multiple detection plug-ins can be used in combination as needed, which is flexible and convenient, can quickly complete the measurement of multiple physical parameters of the accelerator, can perform detection at multiple angles, and is highly practical. However, the following shortcomings still exist.

[0004] The above-mentioned multifunctional quality control phantom of radiotherapy equipment has four sets of height-adjustable support feet arranged at the bottom of the quality control phantom. When in use, the support feet need to be adjusted separately to complete the height adjustment of the quality control phantom, and the levelness of the quality control phantom is detected by a level detection device. This not only leads to a long adjustment cycle of the quality control phantom and is very inconvenient to adjust, but also has low detection efficiency. Therefore, an automatic leveling device for an accelerator quality control phantom is provided to solve the above problems. Utility Model Content
