System for Inducing Respiration Using Biofeedback Principle

摘要

Disclosed herein is a system for processing a biofeedback-treated, respiration-induced signal image using the biofeedback principle, wherein a process for processing the respiration-induced signal image comprises the steps of: (a) acquiring a respiration-induced signal image from a treatment site of a patient in need of radiotherapy treatment using a photographing device; (b) binarizing the acquired image of step (a) using a threshold value; (c) determining whether the binarized image of step (b) is distorted; (d) synthesizing the image; (e) determining whether the synthesized image is required to be separated into regions; and (f) performing pattern matching for the respiration-induced signal image. According to the system, a patient can see and control the patient's own motion at a place where the patient's steady respiration or motion is required, and thus the stability of the patient in a radiotherapy treatment process can be ensured.
