摘要： An X-ray diagnostic device according to embodiments includes an X-ray tube, an X-ray detector, a couchtop, a drive mechanism, an input interface, and processing circuitry. The X-ray tube emits X-rays to a subject. The X-ray detector detects X-rays transmitted through the subject. The couchtop has the subject placed thereon. The drive mechanism generates the driving force for moving the couchtop. The input interface accepts instruction operations from an operator regarding the movement of the couchtop. The processing circuitry acquires one of a weight applied to the couchtop and a deflection amount of the couchtop, and determines the driving force to be generated by the drive mechanism based on one of the weight and the deflection amount and on the instruction operation.

摘要： A medical information processing apparatus of an embodiment includes an image acquiring unit, an event acquiring unit, a managing unit, and an output unit. The image acquiring unit sequentially acquires medical images during a treatment procedure for a subject. The event acquiring unit sequentially acquires events in the treatment procedure on the basis of the medical images during the treatment procedure. The managing unit manages the medical images and the events, in association with temporal information on the treatment procedure. The output unit outputs the medical images such that relations between the medical images and the events are able to be known.

摘要： 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.

摘要： According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry acquires correspondence information, based on 3D medical image data of an object, that corresponds a blood vessel to information on a dominant area of the blood vessel in a region of the object. The processing circuitry acquires a plurality of X-ray images each including the blood vessel that are collected at different time phases on the object. The processing circuitry identifies, based on the plurality of X-ray images, a flow changed vessel in which blood flow has changed between the different time phases. The processing circuitry performs registration between the flow changed vessel and the 3D medical image data. The processing circuitry estimates information on the dominant area corresponding to the flow changed vessel based on registration results and the acquired correspondence information.
