Abstract: A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to obtain an image capturing a space in which a manipulation is being performed on an examined subject and non-image information related to at least one of the manipulation, the examined subject, or the space. Also, the processing circuitry is configured to detect a situation having a high possibility for an occurrence of an abnormality in the space, on the basis of the obtained image, the obtained non-image information, and first correspondence information. The first correspondence information indicates a correspondence relationship between two or more images capturing the space, non-image information, and abnormalities having a high possibility of occurring in the space.

Abstract: A medical image-processing apparatus according to an embodiment includes processing circuitry configured to determine a position of a feature point of a device in a first X-ray image, and generate a superimposed image in which a 3D model expressing the device is superimposed on the first X-ray image or a second X-ray image that is acquired later than the first X-ray image. The processing circuitry is configured to superimpose the 3D model on the first X-ray image or the second X-ray image at a position based on the position of the feature point.

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: The X-ray diagnostic apparatus according to a present embodiment includes processing circuitry. The processing circuitry is configured to: generate an X-ray image of an object by irradiating the object with X-rays; acquire an evaluation result of at least one of elasticity evaluation of a blood vessel of the object and thickness evaluation of a wall of the blood vessel of the object; generate a superimposed image in which the evaluation result is superimposed on the X-ray image; and display the superimposed image on a display.
