Abstract

The invention relates to a stereotactic radiotherapy system quality control detection motif and method. The motif part mainly comprises a multi-stage phantom connected by a phantom connection rod. A head mold groove is arranged on one end of the multi-stage phantom. The head mold groove is connected with one end of a head mold connection rod. The other end of the head mold connection rod is connected with a head mold. The head mold is provided with a head mold insertion plate groove. The multi-stage phantom is provided with an X-Y direction insertion plate groove, a Y-Z direction insertion plate groove and an ionization chamber insertion plate groove. According to the motif provided by the invention, a novel structure is designed, and each part of a human body can be accurately detected.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a phantom and method for quality control detection of a stereotactic radiotherapy system. Background technique [0002] Gamma Knife, also known as stereotactic gamma-ray radiation therapy system, is a therapeutic device that integrates modern computer technology, stereotactic technology and surgical technology. , Lethally destroy the tissue in the target point, while the radiation passes through the normal tissue of the human body with almost no damage, and the dose is sharply reduced, so the boundary between the treatment irradiation range and the normal tissue is very obvious, and the edge is like a knife cut, which is vividly called "Gamma Knife". [0003] With the increase of years and times of use, the irradiation accuracy of Gamma Knife will also change accordingly. Due to the particularity of radiotherapy, large errors will cause irreparable consequences and basically fa...
