Abstract
A tumor tracking control device () performs windowing process on a captured image A () and a captured image B (), measures a position of a marker () using the captured image A () and the captured image B () after performing the windowing process, and generates a signal capable of controlling irradiation with radiation based on the position of the marker (). Accordingly, it is possible to provide a tumor tracking apparatus and an irradiation system which are capable of tracking an object to be tracked without erroneous detection, even in a case where a structure similar to the object to be tracked is in the vicinity of the object to be tracked, in tumor tracking.
