Abstract: A radiation fluoroscopy apparatus detects a marker and includes a control element, an image generation element 61 that generates an image including an embedded marker inside the body of the subject based on a transmitted X-ray. A device candidate detection element 62 detects the candidate of the marker, the local structure detection element 63 detects the local structure in the target region in a proximity of the candidate point of the marker, the device determination element 64 determines whether the local structure is the device such as, the marker or not, the device location acquisition element 66 acquires the gravity center coordinate of the local structure, and the device tracking element 67 tracks the marker based on the location of the marker in each frame.
