    Collapse overview
    Research of Professor Pan’s lab centers on physics, algorithms, and engineering underpinning tomographic imaging and its biomedical and clinical applications. Dr. Pan and his lab conduct research on advanced theory and algorithms for conventional and spectral computed tomography (CT), positron emission tomography (PET), single-photo-emission computed tomography (SPECT), and tomosynthesis especially digital breast tomosynthesis (DBT) and digital lung tomosynthesis (DLT), supported by grants from federal funding agencies such as NIH and DOD, from state funding agencies, from foundations, and from industry. In collaborating with leading researchers in the field, he and his team have worked on magnetic resonance imaging (MRI) and have also investigated emerging imaging techniques, including electron-paramagnetic resonance imaging (EPRI), phase-contrast CT, and photo-acoustic tomography (PAT), among others. In recent years, he and his team have developed programs that translate theoretical concepts and methods to biomedical application work that includes developing innovative hardware systems and workflows, enabled by advanced algorithms, with a strong emphasis on the relevance and impact of imaging technological solutions tailored to specific applications of biomedical and/or clinical significance. Dr. Pan's lab has established continuous, close clinical and industrial collaboration. Dr. Pan is a Fellow of AAPM, AIMBE, IAMBE, IEEE, OSA, and SPIE.
