  • X-ray diagnostic apparatus and medical image processing apparatus
    Patent number: 10736593
    Abstract: An X-ray diagnostic apparatus according to the embodiment includes an X-ray tube, an X-ray detector, image generating unit generating time-series medical images of vasoganglion in a predetermined organ of a subject, region setting unit setting a first upstream and downstream region of a stenosis location in a first blood vessel in the vasoganglion on the medical images, curve generating unit generating a stenosis upstream and downstream curve indicating a change in pixel value in the time-series based on pixel values included in the first upstream and downstream region respectively, stenosis index generating unit generating a stenosis index indicating the degree of stenosis in the first blood vessel based on the stenosis upstream and downstream curve, and display unit displaying the stenosis index.

  • METHOD AND SYSTEM FOR DETERMINING TIME-BASED INDEX FOR BLOOD CIRCULATION FROM ANGIOGRAPHIC IMAGING DATA
    Publication number: 20140086461
    Abstract: A predetermined time-based index ratio such as time-based fractional flow reserve (FFR) is determined for evaluating a level of blood circulation between at least two locations such as a proximal location and a distal location in a selected blood vessel in the region of interest. One time-based FFR is obtained by normalizing a risk artery ratio by a reference artery ratio.
