Abstract: According to one embodiment, a medical image diagnostic apparatus includes a storage memory, processing circuitry, and a display. The storage memory stores data of a plurality of FFR distribution maps constituting a time series regarding a coronary artery, and data of a plurality of morphological images corresponding to the time series. The processing circuitry converts the plurality of FFR distribution maps into a plurality of corresponding color maps, respectively. The display displays a plurality of superposed images obtained by superposing the plurality of color maps and the plurality of morphological images respectively corresponding in phase to the plurality of color maps. The display restricts display targets for the plurality of color maps based on the plurality of FFR distribution maps or the plurality of morphological images.

Abstract: A medical apparatus according to an embodiment includes a processing circuitry. The processing circuitry is configured: to receive an input of test result information including a test result of each of tests that are related to a biological valve and were carried out at two or more different times; to estimate one of a test time for a follow-up observation of the biological valve and a test time for replacing the biological valve, on the basis of a chronological change in an open/close state of the biological valve derived from the received test result information; and to output the estimated test time.

Abstract: A medical information processing apparatus of an embodiment includes processing circuitry. The processing circuitry acquires a plurality of pieces of output data respectively output from a plurality of analysis processes to which medical image data is input as input data. The processing circuitry selectively extracts, from the pieces of output data, a plurality of pieces of output data based on an extraction condition. The processing circuitry performs control to display a plurality of pieces of information corresponding to the pieces of extracted output data and a medical image related to any one piece of the information and generated from the medical image data.

Abstract: The medical image diagnostic apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to: generate medical volume data including bones and an organ; identify, based on the volume data, the organ and an abnormal bone having an abnormal region of the bones; calculate, based on the organ and the abnormal bone of the volume data, an influence rate on the organ by the abnormal bone; and superimpose data indicating the influence rate on the image based on the volume data, thereby displaying the superimposed image on a display.
