X-RAY MOVING BODY TRACKING DEVICE, X-RAY MOVING BODY TRACKING METHOD, AND IMAGE PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an X-ray moving body tracking device capable of tracking a tracking target with a higher degree of precision.;SOLUTION: An X-ray moving body tracking device includes a pulse voltage generation part for generating a first pulse voltage and a second pulse voltage different in magnitude from the first pulse voltage at a predetermined interval, an X-ray generation part for generating a first pulse X-ray and a second pulse X-ray based on the first pulse voltage and the second pulse voltage, an X-ray imaging part for imaging first X-ray image data corresponding to the first pulse X-ray passing through a subject, and second X-ray image data corresponding to the second pulse X-ray passing through the subject, an image processing part for generating emphasized image data for emphasizing contrast of a marker region for radiation therapy in the subject using the first X-ray image data and the second X-ray image data, and a detection part for detecting the position of the marker for radiation therapy based on the emphasized image data.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
