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

An X-ray diagnostic system comprising:

• a robot catheter system;
• and
• a processor configured to:
• sequentially acquire ultrasonic image data generated from a signal collected from a detector of an ultrasonic catheter that is inserted into a body of a subject;
• collect a plurality of pieces of X-ray image data that are captured from a plurality of directions and detect the ultrasonic catheter and a treatment device on the X-ray image data;
• calculate coordinates indicating a current position of the treatment device on the X-ray image data based on operation information about a user operation for the ultrasonic catheter received from the robot catheter system, an opaque marker that is present at a leading end of the treatment device included in an object drawn in the ultrasonic image data, and a result of detection by the detector;
• and
• display 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.

An X-ray diagnostic method performed by an X-ray diagnostic apparatus, the method comprising:

• sequentially acquiring ultrasonic image data generated from a signal collected from a detector of an ultrasonic catheter that is inserted into a body of a subject;
• detecting including collecting a plurality of pieces of X-ray image data that are captured from a plurality of directions and detecting the ultrasonic catheter and a treatment device on the X-ray image data;
• first calculating including calculating coordinates indicating a current position of the treatment device on the X-ray image data based on operation information about a user operation for the ultrasonic catheter received from a robot catheter system, an opaque marker that is present at a leading end of the treatment device included in an object drawn in the ultrasonic image data, and a result of detection by the detector;
• and
• display control including displaying 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.
