研究领域

As a research asssociate for the physics of medical imaging, my focus is on system modeling for optimization of X-ray CT imaging chain, and the integration in novel reconstruction algorithms. My particular areas of interest are: 1) improving the task-based optimization of image quality through numerical models; 2) advanced modeling of physics in statistical reconstruction; 3) accelerated Monte Carlo methods in CT imaging for, e.g., scatter estimation and correction and dosimetry;and 4) experimental validation of such approaches and application to development of novel imaging devices.
