As part of a new Duke and NIH collaboration focusing on harnessing the potential of emerging photon-counting CT technology, Jayasai Rajagopal (PhD student, Advisor: Dr. Samei), will be working with a prototype photon-counting CT system (Siemens, Germany) at the NIH Clinical Center under the supervision of Dr. Brad Wood. His work will focus on evaluation of image quality and the benefits offered by photon-counting CT when compared to conventional and dual-energy methods.
