Abstract: In one embodiment, an X-ray diagnostic apparatus can communicate with a controller configured to operate a catheter robot capable of moving an inserted device within the object and comprises a display and processing circuitry. The display is configured to display at least one fluoroscopic image of an object. The processing circuitry is configured to receive a control signal indicating a content of an operation on the catheter robot from the controller, acquire a plurality of fluoroscopic images of the object by irradiating the object with X-rays, control X-ray irradiation to the object, cause the display to display the plurality of fluoroscopic images to be sequentially acquired when the X-ray irradiation is performed, generate a plurality of reproduced images based on the plurality of fluoroscopic images acquired before a stop of the X-ray irradiation and cause the display to display the plurality of reproduced images when the X-ray irradiation is stopped.

Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry that obtains first X-ray images, a second X-ray image taken later than the first X-ray images, first biological information to a periodic movement of a subject at the times of taking the first X-ray images and second biological information to a periodic movement of the subject at the time of taking the second X-ray image; detects a characteristic position to a first device from each of the first X-ray images; associates the characteristic position with a time phase in the first biological information, based on the first X-ray images and first biological information; and displays device information to the first device superimposed on the second X-ray image, by using a result of the associating and time phase in the second biological information.

Abstract: A medical image processing apparatus of an embodiment includes processing circuitry acquiring an X-ray image about a subject, acquiring an ultrasonic image data about the subject, extracting an object contained in the X-ray image, and performing processing based on the position of the extracted object on the ultrasonic image data in accordance with the relative positional relation between a coordinate system in the X-ray image and a coordinate system in the ultrasonic image data to generate a composite image as a combination of a processed ultrasonic image data after being subjected to the processing and the X-ray image.
