Dr. Wei Zhao's research work in the past has focused on the investigation of amorphous selenium flat-panel detectors for radiography and fluoroscopy. She also worked on the development of cesium iodide based flat-panel detectors for medical imaging. Her current research interest focus on the investigation of imaging performance and design optimization for amorphous selenium flat-panel detectors for digital mammography and digital tomosynthesis. Her research work also involves developing advanced detector concepts for improved imaging performance at low-dose and high-frame rates.
