 Overview
My research interests focus on x-ray cone beam CT imaging, including both conventional attenuation-based imaging and novel phase-contrast imaging. Current research projects include:
1. developing flat-panel detector-based cone beam CT systems,
2. applying the cone beam CT technique for breast imaging, vascular imaging, small animal imaging and etc,
3. developing the phase-contrast cone beam CT imaging technique into a practical imaging modality.
