Abstract: An X-ray diagnostic apparatus according to an embodiment includes a storage, an imaging equipment, a display, an input interface, and processing circuitry. The storage memorizes medical images. The imaging equipment includes an X-ray tube configured to emit X-rays toward a subject and a detector configured to detect X-rays emitted from the X-ray tube. The display displays a plurality of medical images including X-ray images captured by the imaging equipment. The input interface accepts an operation instructing storage of a medical image displayed on the display. The processing circuitry identifies a medical image associated with a last-executed, targeted operation, among targeted operations related to any of medical images displayed on the display, and, when the input interface has accepted an operation instructing storage of a medical image displayed on the display, causes the storage to memorize the identified medical image.

Abstract: An X-ray diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry determines a concentration of a contrast agent in contrast-enhanced image collection based on first reference information in which a recommended contrast in a contrast-enhanced image is associated with each region of interest to be subject to collection of the contrast-enhanced image, and on second reference information that indicates a relation among a generation condition of an X-ray, a concentration of a contrast agent, and a contrast. The processing circuitry calculates setting information of an injector to inject a contrast agent to the subject based on the determined concentration of a contrast agent.

Abstract: According to one embodiment, a medical information display control apparatus includes processing circuitry. The processing circuitry is configured to accept a pointer operation signal corresponding to an operation by a user, acquire a plurality of medical information screen data laid out as a display screen, detect a first pointer drawn in one of the plurality of medical information screen data and specify first pointer coordinates indicating a position of the first pointer, calculate second pointer coordinates indicating a position of a second pointer drawn on the display screen based on the pointer operation signal, and output a pointer movement signal based on the pointer operation signal so as to substantially match the first pointer coordinates with the second pointer coordinates.

Abstract: An X-ray diagnostic apparatus according to an embodiment includes an X-ray detector, a grid, a slide mechanism, a rotary mechanism, and an arm. The X-ray detector detects X-rays emitted from an X-ray tube. The grid has a fixed relative position to the X-ray detector and is provided with stripes extending in a first direction to remove scattered rays included in the X-rays. The slide mechanism includes at least one slide rail along the first direction and holds the X-ray detector so as to slide in the first direction. The rotary mechanism includes a rotation shaft and rotatably holds the slide mechanism. The arm holds the rotary mechanism and is operable.

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.
