Abstract
A radiation fluoroscopy apparatus provides radiation fluoroscopy from at least three positions without moving the radiation irradiation element and the radiation detector. A control element includes a detection rate calculation element that respectively calculates the detection rate of the position of the marker in a first imaging system having a first X-ray tube and a first flat panel detector, a second imaging system having a second X-ray tube and a second flat panel detector, and a third imaging system having a third X-ray tube and a third flat panel detector, and a fourth imaging system having a fourth X-ray tube and a fourth flat panel detector; and an imaging system selection element that selects the two imaging systems, used for X-ray fluoroscopy, out of one of the imaging systems based on a detection rate of a position of a marker calculated by a detection rate calculation element.
