Abstract

According to one embodiment, An X-ray diagnostic apparatus includes an X-ray generator that generates X rays, an X-ray detector that detects the X rays generated by the X-ray generator and having passed through a subject, an X-ray restrictor that restricts an irradiation range on a detection surface of the X-ray detector of the X rays generated by the X-ray generator, a signal input unit that inputs a biomedical signal related to the subject, a signal detector that detects a biomedical change from the biomedical signal and also outputs an extension switching signal, and an X-ray restrictor controller that controls the X-ray restrictor such that the irradiation range of the X rays is extended in response to output of the extension switching signal.

Description

technical field [0001] Embodiments of the present invention relate to an X-ray diagnostic apparatus. Background technique [0002] In recent years, techniques for reducing the radiation dose in X-ray photography using an X-ray diagnostic apparatus have been developed. As one of such techniques, there is a point perspective function used in catheter therapy using an X-ray diagnostic apparatus, and the like. In the point fluoroscopy function, the user designates a region of interest on which X-rays are to be irradiated on the fluoroscopy monitor. And, in order to irradiate the region of interest with X-rays, the X-ray diaphragm is controlled by the X-ray diagnostic apparatus. Then, an X-ray fluoroscopic image related to a region of interest based on point fluoroscopy is superimposed and displayed on a still image of a full fluoroscopy (Last Image Hold: frozen image, hereinafter referred to as LIH image) immediately before starting point fluoroscopy. Therefore, compared with...
