  • Publication number: 20220383494
    Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires image data including image data of a blood vessel of a subject. The processing circuitry performs analysis related to the blood vessel by using the image data, and specifies a region of interest in the blood vessel based on a result of the analysis. The processing circuitry performs fluid analysis on a region other than the region of interest at a first accuracy, and performs fluid analysis on the region of interest at a second accuracy that is higher than the first accuracy.

  • Patent number: 9433393
    Abstract: An X-ray diagnosis apparatus includes: a reference value calculating unit that calculates a reference value used for normalizing a flow of a contrast material, on the basis of a chronological transition of a signal intensity of the contrast material in a predetermined region, for each of a plurality of groups of X-ray images chronologically taken while using the contrast material; an index image generating unit that normalizes, for each of the plurality of groups of X-ray images, the flow of the contrast material at each of pixels by using the reference value calculated by the reference value calculating unit and that generates an image in which a feature value of the normalized flow of the contrast material is reflected in each of the pixels; and a displayed image calculating unit that causes a predetermined display unit to display the image generated by the index image generating unit.
