Research Focus

Quantitative noninvasive cardiac imaging. Automated coronary artery analysis from cardiac CT - measurement of total plaque burden and epicardial fat burden. Automated derivation of imaging measures from cardiac images. Improving image quality and image acquisition techniques, and reducing radiation dose in cardiac CT and cardiac PET-CT.

Research Contributions

Automated derivation of imaging measures from noninvasive cardiac image data, particularly cardiac CT, clinical implementation of novel automated computer processing algorithms, and the application of these tools to solve key clinical problems.

Current investigations include:

Automated measurement of non-calcified and calcified coronary plaque from coronary CT Angiography. Automated noninvasive detection of coronary plaque lesions. Automated noninvasive measurement of epicardial and thoracic fat and their clinical value. Detection of coronary plaque inflammation with PET-CT. Improvement of image quality and radiation dose reduction in cardiac CT and cardiac PET-CT.
