  • METHOD AND SYSTEM FOR AUTOMATICALLY GENERATING AND ANALYZING FULLY QUANTITATIVE PIXEL-WISE MYOCARDIAL BLOOD FLOW AND MYOCARDIAL PERFUSION RESERVE MAPS TO DETECT ISCHEMIC HEART DISEASE USING CARDIAC PERFUSION MAGNETIC RESONANCE IMAGING
    Publication number: 20210068676
    Abstract: A computer-implemented method for automatically generating a fully quantitative myocardial blood flow map, comprising: receiving myocardial perfusion magnetic resonance imaging (MRI) images and arterial input function (AIF) MRI images; correcting a motion of a heart in the myocardial perfusion MRI images and the AIF MRI images, thereby obtaining motion corrected myocardial perfusion MRI images and motion corrected AIF images; correcting an intensity of the motion corrected myocardial perfusion MRI images and an intensity of the motion corrected AIF images, thereby obtaining surface coil intensity corrected MRI images and surface coil intensity corrected AIF images; using the surface coil intensity corrected MRI images and the surface coil intensity corrected AIF images, determining time-signal intensity characteristics and segmenting a left ventricle myocardial tissue region; and generating the myocardial blood flow map using the motion corrected myocardial perfusion MRI images, the left ventricle myocardial

  • Computer-aided diagnosis system for thoracic computer tomography images
    Patent number: 6795521
    Abstract: A method of detecting and analyzing abnormalities, like lung nodules, in thoracic computer tomography (CT) images uses digital image processing techniques and adaptive computing methods. The techniques include an automatic detection process to detect candidate abnormalities, an image matching process to match CT slices from two different CT scans, and a measurement process that determines parameters of the candidate abnormalities. Final results and processed CT images are displayed on a user interface.
