Abstract: According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry specifies, before position alignment between a first X-ray image and a second X-ray image which is acquired with a device inserted, a device area candidate in the second X-ray image as a candidate of an area where the device appears. The processing circuitry performs the position alignment using first processing of removing the specified device area candidate or second processing of reducing a contribution of the specified device area candidate.

Abstract: The X-ray imaging apparatus according to the embodiment includes an X-ray irradiator and processing circuitry. The X-ray irradiator is placed in a surgery room. The processing circuitry is configured to sequentially acquire a position of each staff member presenting in the surgery room during a procedure using the X-ray irradiator. The processing circuitry is configured to sequentially acquire an exposure dose of each staff member from a dosimeter. The processing circuitry is configured to associate the position of each staff member and the exposure dose of each staff member with a time, and sequentially record association data in a memory circuit. The processing circuitry is configured to display association data indicating a relation between the position of each staff member and the exposure dose of each staff member in an identifiable manner on a display.

Abstract: A medical image processing apparatus includes processing circuitry. The processing circuitry obtains activity position data related to positions of activity regions that bring a site of an examined subject into an activity and a blood vessel image rendering a three-dimensional blood vessel related to the activity regions. The processing circuitry performs a registration between the activity position data and the blood vessel image. The processing circuitry calculates a positional relationship between at least one of the activity regions and the blood vessel, on the basis of a result of the registration. On the basis of the positional relationship, the processing circuitry causes a display to display information about positioning a device capable of receiving, within the blood vessel of the examined subject, electrical signals from the activity regions.

Abstract: An X-ray diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry acquires an image of a movable range of a movable unit that can move freely in an examination room where X-ray imaging of a subject is performed, from a camera provided in the examination room, determines the classification of an object present in the movable range on the basis of the image, and controls the operation of X-ray imaging on the basis of the determination results.
