Research & Publications
My primary research has been focused on new developments of automatic quantification and iterative image restoration and reconstruction methods for nuclear cardiac tomographic imaging. The new developments promise to improve image resolution and enhance detection of abnormalities of myocardial perfusion and left ventricular function. My recent work is focused on small animal imaging techniques using hybrid coded aperture collimation, and developments of “hot-spot” quantification methods for molecular targeted cardiac images using innovative stochastic methodology incorporated with dual-isotope SPECT and hybrid SPECT/CT imaging techniques. I have been also directing a developmental project for remote reading/processing tools for nuclear cardiac imaging using secured cloud computing technology.
