X-ray diagnostic apparatus, x-ray diagnostic system, and x-ray diagnostic method

Abstract

An X-ray diagnostic apparatus according to an embodiment includes a processor. The processor sequentially acquires ultrasonic image data generated from a signal collected from a detector of an ultrasonic catheter that is inserted into a body of a subject. The processor collects a plurality of pieces of X-ray image data acquired from a plurality of directions and detects the ultrasonic catheter and a treatment device on the X-ray image data. The processor calculates coordinates indicating a current position of the treatment device on the X-ray image data based on information about a user operation for the ultrasonic catheter received from a robot catheter system, the treatment device detected on the ultrasonic image data, and a result of detection by the detector. The processor displays a display image that is obtained by superimposing positional information including the coordinates indicating the current position of the treatment device onto the X-ray image data.
