Abstract: A medical information processing apparatus of an embodiment includes processing circuitry. The processing circuitry acquires biometric data regarding a subject. The processing circuitry identifies reference data regarding a first feature amount on the basis of the biometric data. The processing circuitry acquires a second feature amount by inputting the first feature amount included in the biometric data into a model capable of mutually converting the first feature amount and the second feature amount. The processing circuitry derives pseudo-feature data regarding the first feature amount simulated by inputting the second feature amount into the model. The processing circuitry determines reliability scores with respect to the biometric data on the basis of the reference data and the pseudo-feature data.

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.
