Research Areas

Main research objectives include:

  • Novel quantitative methods for image analysis
  • Automated extraction of imaging biomarkers and validation
  • Improve identification of patients at risk of disease and adverse outcomes
  • Improve the accuracy of diagnostic tests
  • Improve patient outcomes and patient management


Our current research focus includes:

  • Measurement of epicardial and thoracic fat (QFAT software) from non-contrast CT. We have shown epicardial fat measured by this clinical research tool to be associated with coronary atherosclerosis, coronary calcium progression, major adverse cardiovascular events and myocardial ischemia.
  • Automated measurement of coronary plaque volume (noncalcified and calcified) from coronary CT Angiography (AUTOPLAQ software).
