    Abstract: A medical image processing device according to an embodiment includes processing circuitry. The processing circuitry detects a contrast medium from a medical image. The processing circuitry sets a first region of interest and a second region of interest in the medical image. The processing circuitry calculates a density ratio between a density of the contrast medium included in the first region of interest and a density of the contrast medium included in the second region of interest.

    Abstract: According to one embodiment, the analysis apparatus includes processing circuitry. The processing circuitry acquires a plurality of medical images respectively corresponding to a plurality of consecutive frames, generates first position data and second position data indicating positions of a moving object in a subject for a first medical image corresponding to a first frame and a second medical image corresponding to a second frame that is two or more frames prior to the first frame of the plurality of medical images, calculates a vector representing a movement of the moving object based on the first position data and the second position data, and generates display image data having a shape representing the vector.

    Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to generate contrast image data on the basis of a contrast signal acquired from an examined subject to whom a contrast agent is administered. The processing circuitry is configured to generate blood flow image data on the basis of a blood flow signal estimated by performing a filtering process on the contrast signal. The processing circuitry is configured to output information indicating a region where the contrast agent is stagnant within a region of interest, on the basis of the contrast image data and the blood flow image data.

    Abstract: The medical image processing apparatus according to the present embodiment includes processing circuitry. The processing circuitry is configured to acquire contrast image data generated by imaging a subject. The processing circuitry is configured to input the acquired contrast image data to a learned model to generate a time phase data classified according to a contrast state of a lesion area with a contrast agent included in the acquired contrast image data, the learned model being for generating the time phase data based on the acquired contrast image data.
