After photographing images (80a, 80b, 80c…80n) that include a marker (M), the portions of the marker (M) are extracted to obtain template images (81a, 81b, 81c…81n). When starting treatment on a subject (57), fluoroscopy is carried out on a region that includes the marker (M). Template matching is then performed using the multiple template images (81a, 81b, 81c…81n) on the region (83) that includes the marker (M) in an image (82) which is photographed at regular intervals. That is, all of the multiple template images (81a, 81b, 81c…81n) are sequentially matched against the region (83) that includes the marker (M) in the image (82) which is photographed at regular intervals. |
