Abstract: According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry is configured to acquire a two-dimensional first X-ray image based on X-ray imaging using a first continuous X-ray spectrum, and acquire a two-dimensional second X-ray image based on X-ray imaging using a second continuous X-ray spectrum different from the first continuous X-ray spectrum. Further, the processing circuitry is configured to generate a two-dimensional virtual third X-ray image that simulates an X-ray image using a third continuous X-ray spectrum different from the first continuous X-ray spectrum and the second continuous X-ray spectrum, based on the first X-ray image and the second X-ray image.

Abstract: A medical-image processing apparatus and a medical-image diagnostic apparatus according to an embodiment include an acquisition unit, a generation unit, an identification unit, and a display control unit. The acquisition unit acquires a medical image containing a blood vessel collected by the medical-image diagnostic apparatus. The generation unit generates an anatomical structure model based on the medical image acquired by the acquisition unit. The identification unit identifies a position, on the medical image, of an index relating to blood flow analyzed through fluid analysis using the anatomical structure model. The display control unit displays the position of the index on the medical image, and also displays the index associated with the position of the index on the medical image.

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.
