Implementation method and system for 4D gamma knife plan based on breathe monitoring

Abstract

The invention discloses an implementation method and system for a 4D gamma knife plan based on breathe monitoring. A 4D gamma knife treatment plan subsystem is used for generating a 4D gamma knife treatment plan of a corresponding patient, and the 4D gamma knife treatment plan is sent to a treatment control subsystem; a breathe monitoring subsystem is used for collecting and storing patient breathe signals; a breathe predicating subsystem is used for setting up a breathe predicating reference signal parameter library of the patient and predicating the breathe time phase of the next moment in the practical treatment process of the current patient, the treatment control subsystem and the 4D gamma knife treatment plan are combined, and a radiotherapy subsystem is controlled to call corresponding gamma knife projecting range parameters to conduct actions; the radiotherapy subsystem is used for calling the corresponding gamma knife projecting range parameters to conduct radiotherapy and record treatment data in real time according to control commands of the treatment control subsystem. According to the implementation method and system for the 4D gamma knife plan based on breathe monitoring, the design of the 4D gamma knife plane can be efficiently achieved, the patient does not need to hold the breath in the treatment process, and the application range is wide.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to a method and system for implementing a 4D (four-dimensional) Gamma Knife plan based on respiratory monitoring. 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. It geometrically focuses the gamma rays emitted by cobalt-60, In the lesion, it destroys the tissue in the target point one-time and lethally, while the ray passes through the normal tissue of the human body with almost no harm, and the dose is sharply reduced. Therefore, the boundary between the treatment irradiation range and the normal tissue is very obvious, and the edge is like a knife cut. People The image is called "Gamma Knife". [0003] 4D radiotherapy is four-dimensional radiotherapy, which is an implementation of IGRT (image-guided...

AI Technical Summary

Problems solved by technology

[0004] Existing 4D radiotherapy plans for accelerators only carry out 4D target area delineation. The plan design is carried out for a certain phase in the 4D image. During the treatment, the patient is asked to hold his breath at the time phase used in the plan design. This implementation method can only be used for patients who are in a good state of autonomous breathing control and are willing to cooperate, and its scope of application is narrow, and because the patient's breath holding time is limited, each treatment will seriously prolong the patient's treatment time
