Overview


Mridul Bhattarai, MS, is a Ph.D. student in the Medical Physics Graduate Program of the Department of Radiology, Duke School of Medicine. He completed his master's degree in the same program, during which he extensively worked on photon-counting CT, the latest clinical CT system. His study focused on various aspects of this technology, including its advantages compared to conventional CT scanners and its non-idealities.

Currently, Mridul serves as a research assistant at the Center for Virtual Imaging Trails (CVIT) and the Carl E. Ravin Advanced Imaging Laboratories (RAILabs). His research work primarily revolves around CT imaging, biomedical imaging simulation, modeling of CT systems, and evaluating the performances of CT systems and protocols for quantifying lung diseases, such as chronic obstructive pulmonary disease (COPD).
