I am a Professor of Imaging Physics at the University of Texas MD Anderson Cancer Center. I have been in the field of Imaging Physics for more than 20 years since I graduated from University of Wisconsin-Madison in 1999. I lead a group of 7 imaging physics faculties and 1 senior medical physicist, providing imaging physics clinical services for CT, General Radiography/Fluoroscopy, Interventional Radiology and Mammography. My primary area of research lies in CT, ultrasound and interventional radiology. My two major CT research projects involved CT radiation dose assessment and reduction including evaluation of iterative reconstruction techniques, as well as the impact of metal artifacts reduction on bone lesion detection using custom designed arthroplasty phantom. I was also involved in the clinical research to provide accurate estimation of skin dose from fluoroscopy procedures. I am currently involved in a research project related to the new photon counting detector CT. One of the goals of the project is to design an anthropomorphic phantom with simulated spherical liver lesions with and without iodinated contrast media. I am very excited about the potentials of the new photon counting detector CT in diagnostic imaging.
