  • Moving body tracking apparatus, radiation therapy system including the same, program, and moving body tracking method
    Patent number: 11282244
    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 target 2 from at least two directions, and the moving body tracking control apparatus 30A that obtains a position of the target 2 from the fluoroscopic images acquired by the fluoroscopic apparatus. The moving body tracking control apparatus 30A creates a simulated fluoroscopic image from the CT image including the target 2, creates a two-dimensional region including the target 2 from 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 target 2 from a plurality of matching results.
