DEVICE FOR TRACING ORGAN MOTION INDUCED BY RESPIRATION IN REAL TIME

摘要

A device for tracing an organ motion induced by respiration in real time is provided to maximize treatment efficiency in a patient's radiation treatment by tracing a position of a certain part of the organ by the respiration in real time, and preparing a position displacement data of a treatment part. The device includes: an irradiator(20); a visible ray generating unit(30) for converting the radiation irradiated from the irradiator into a visible ray; a camera(35) for taking a photograph of an image formed by the visible ray; a signal converter(40) for converting the image from the camera into a digital image signal; and a computer processing device(50) comprising a display part(51) for displaying a digital image on a screen, an input part(52) for selecting a certain part of the displayed image, a control part(53) for preparing a position displacement data according to a time change of the selected certain part, and a storage part(54) for storing the position displacement data and the digital image.
