Abstract
Provided are a moving body tracking apparatus that contributes to shortening treatment time and a radiation therapy system including the moving body tracking apparatus, a program, and a moving body tracking method. The moving body tracking apparatus includes a fluoroscopic apparatus that acquires fluoroscopic images including the targetfrom at least two directions, and the moving body tracking control apparatusA that obtains a position of the targetfrom the fluoroscopic images acquired by the fluoroscopic apparatus. The moving body tracking control apparatusA creates a simulated fluoroscopic image from the CT image including the target, creates a two-dimensional region including the targetfrom the simulated fluoroscopic image as a template, matches each of at least two fluoroscopic images with the template, and obtains a three-dimensional position of the targetfrom a plurality of matching results.
