摘要:
According to one embodiment, A movable part tracking and treatment apparatus, includes: an acquisition unit adapted to acquire a three-dimensional moving image by imaging an inside of a body of a patient a first projection image generation unit adapted to generate a first projection moving image by projecting the three-dimensional moving image on a two-dimensional surface from a fixed direction, the three-dimensional moving image including a tracing target and an affected part area that are part of internal organs in a displaced state, an affected part image extraction unit adapted to extract the displaced affected part area from the first projection moving image, a tracing target image extraction unit adapted to extract the displaced tracing target from the first projection moving image, a first parameter derivation unit is adapted to derive a first parameter indicative of position information on a beam irradiation point selected from the displaced affected part area in the first projection moving image, and a second parameter derivation unit adapted to derive a second parameter necessary to extract the corresponding tracing target from another projection moving image based on the tracing target extracted from the first projection moving image.
