PROBLEM TO BE SOLVED: To simplify rotation photographing using a first photographing system and a second photographing system.SOLUTION: An X-ray diagnostic apparatus according to an embodiment comprises a first photographing system, a second photographing system and a processing circuit. The first photographing system rotatably holds a first X-ray tube and a first X-ray detector. The second photographing system rotatably holds a second X-ray tube and a second X-ray detector, and can set a rotation center independently of the first photographing system. The processing circuit substantially matches the rotation center of the first photographing system with that of the second photographing system in rotation photographing for collecting projection data for use in generation of a three-dimensional image, by using the first photographing system and the second photographing system.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】第１の撮影系及び第２の撮影系を用いた回転撮影を簡便にすること。【解決手段】実施形態のＸ線診断装置は、第１の撮影系と、第２の撮影系と、処理回路と、を備える。第１の撮影系は、第１のＸ線管及び第１のＸ線検出器を回転可能に保持する。第２の撮影系は、第２のＸ線管及び第２のＸ線検出器を回転可能に保持し、かつ、前記第１の撮影系とは独立に回転中心を設定可能である。処理回路は、前記第１の撮影系及び前記第２の撮影系を用いて三次元画像の生成に用いる投影データを収集するための回転撮影において、前記第１の撮影系の回転中心と前記第２の撮影系の回転中心とを実質的に一致させる。【選択図】図１
