Biography
Tiezhi Zhang, PhD, is an associate professor of radiation oncology at the Radiation Oncology department. Dr. Zhang earned a PhD in Medical Physics from University of Wisconsin 2004. He joined the Washington University faculty in 2014. He is certified in Therapeutic Radiological Physics by the American Board of Radiology.
Research
Dr. Zhang is developing novel X-ray imaging technologies for image-guided radiotherapy. His lab is developing high brightness multi-pixel thermionic emission X-ray (MPTEX) sources, as well as a novel Tetrahedral beam CT (TBCT) using the MPTEX source. TBCT is a compact volumetric CT system that is immune to the problems of current cone beam CT system by using a new scanning geometry. It can produce high-quality CT images for image-guided radiotherapy and intervention.
