Abstract

The moving object tracking apparatus emphasizes an image with specific size in each of fluoroscopic images derived from two or more paired fluoroscopic radiographic devices, obtains a value indicating certainty degree of detecting a candidate position of the object to be tracked on the image subjected to the emphasizing process, extracts the candidate position based on the value indicating the certainty degree of detection, calculates a value indicating a correlation between the candidate position extracted from images picked up from two or more directions, and a position of the fluoroscopic radiation generator, detects the position of the object to be tracked based on the value indicating the certainty degree of detection, and the value indicating the correlation, and controls irradiation of radiation to an irradiation target based on the detected position of the object to be tracked.
