X-RAY DYNAMIC BODY TRACKING DEVICE, AND X-RAY DYNAMIC BODY TRACKING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an X-ray dynamic body tracking device capable of tracking an object to be tracked with higher accuracy.;SOLUTION: The X-ray dynamic body tracking device related to the present embodiment comprises an X-ray irradiation device, an X-ray imaging unit, a subtraction image generation unit, and a detection unit. The X-ray irradiation device irradiates a testee body with a first X-ray having first effective energy and a second X-ray having second effective energy while switching these X-ray alternately for each prescribed time. The X-ray imaging unit images a first X-ray image based on the first X-ray having passed through the testee body, and a second X-ray image based on the second X-ray having passed through the testee body. The subtraction image generation unit generates a subtraction image using the first X-ray image and the second X-ray image. The detection unit detects a position of an object to be tracked in the testee body on the basis of the subtraction image generated by the subtraction image generation unit.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
