Radiotherapy system

By employing triple focusing technology—multi-source focusing, rotational focusing, and lateral arc focusing—combined with modular source devices and sensing devices, high-dose-rate target ablation of radiotherapy equipment can be achieved in a short time. This solves the problems of long treatment time and insufficient protection of organs at risk, thus improving the safety and effectiveness of radiotherapy.

AI Technical Summary

Technical Problem

Existing radiotherapy equipment suffers from problems such as long treatment time, poor patient comfort, and insufficient protection of endangered organs, making it difficult to achieve high-dose-rate target ablation in a short period of time while effectively protecting surrounding normal tissues.

Method used

Employing a triple focusing technology of multi-source focusing, rotational focusing, and lateral arc focusing, combined with a modular radiation source device and sensing device, the radiation is focused on the target area from multiple spatial angles. The device is driven by rotation and oscillation to precisely irradiate the target area while protecting normal tissue.

Benefits of technology

It significantly shortens treatment time, improves patient comfort, reduces damage to organs at risk, and enhances the safety and effectiveness of radiotherapy.

Abstract

The present disclosure provides a radiotherapy system. The radiotherapy system comprises: a gantry; a source device arranged on the gantry, the source device comprising a plurality of radioactive sources, a plurality of rays emitted by the plurality of radioactive sources converging at a focal point; a rotating driving device drivingly connected with the source device to drive the source device to rotate around a central axis thereof and maintain the position of the focal point unchanged; and a swinging driving device drivingly connected with the source device to drive the source device to swing along a transverse direction of a subject to be treated and maintain the position of the focal point unchanged. Thus, not only the comfort of the subject to be treated during radiotherapy can be improved, but also the damage to organs at risk can be reduced, and the safety and effectiveness of radiotherapy can be improved.
