Gamma Knife head treatment device and Gamma Knife treatment system

Abstract

A Gamma Knife heat treatment apparatus and a Gamma Knife treatment system. The Gamma Knife heat treatment apparatus comprises a radiation source (220) and a source carrier body (230). The radiation source (220) is arranged on the source carrier body (230) and is used for emitting multiple beams of gamma rays capable of focusing geometrically and forming a focus point (210). The Gamma Knife heat treatment apparatus also comprises a CBCT imaging module (310). The CBCT imaging module (310) comprises a CBCT ball pipe (240) and a dynamic planar detector (250). The ball pipe (240) is mounted onto the source carrier body (230). The dynamic planar detector (250) is mounted onto the source carrier body (230) and arranged on a side opposite to the CBCT ball pipe (240). A vertical line of connection between the CBCT ball pipe (240) and the dynamic planar detector (250) either passes through the focus point (210), or is positioned at a set distance away from the focus point (210). The Gamma Knife head treatment apparatus and the Gamma Knife treatment system allow for implantation of high precision positioning of a head tumor by means of the CBCT imaging module (310), and for fractionated treatment of the head tumor at small doses, thus protecting as much as possible normal tissues of a patient.

Description

technical field [0001] The invention belongs to the field of medical radiation, and in particular relates to a Gamma Knife head treatment device and a Gamma Knife treatment system. Background technique [0002] Gamma Knife is a very advanced radiotherapy equipment, its full name is Gamma Ray Stereotactic Therapy System, it is a therapeutic equipment that integrates modern computer technology, stereotaxic technology and surgical technology, it emits radiation source The gamma rays are geometrically focused and concentrated on the tumor, destroying the tissue within the target once and lethally. [0003] When the existing Gamma Knife treatment device treats head tumors, such as figure 1 The Gamma Knife head treatment shown is fixed with an invasive positioning device (for example: foot nails). Since there is a certain distance between the patient’s head tumor and the foot nails, the foot nails and the U-shaped fixing frame of the treatment bed are fixed. Therefore, the size ...
