摘要： The object of the present invention is to obtain an X-ray positioning apparatus that can perform efficient photographing in accordance with a state of a respiratory waveform when a patient of radiation therapy is positioned. An X-ray positioning apparatus (20) according to the present invention is provided with an X-ray video device (3) that generates second X-ray image data (data2) in which a respiratory signal (sig1) of a patient (45) and first X-ray image data (data1) are related to each other, a positioning computer (1) that generates patient platform control data (cdata1) for controlling a patient platform (12), and a photographing trigger generation apparatus (2) that outputs a photographing trigger signal (sig3) to an X-ray tube (6); the X-ray positioning apparatus (20) is characterized in that the photographing trigger generation apparatus (2) generates the photographing trigger signal (sig3), in accordance with a first frame rate (fr1) and a second frame rate (fr2) that is higher than the first frame rate (fr1), and in that the positioning computer (1) generates the patient platform control data (cdata1), based on a reference image and one X-ray image selected from consecutively photographed images (29) that are photographed at the second frame rate (fr2).
