Dr. Amir H. Goldan is currently a assistant professor of research Radiology at Stony Brook Medicine where he is working on the development and fabrication of medical imaging detectors for positron emission tomography (PET) and digital mammography.
Dr. Goldan received his Ph.D. in electrical and computer engineering from the University of Waterloo, CANADA. During his Ph.D. studies, he introduced the novel concept of unipolar time-differential (UTD) charge sensing in solid-state radiation detectors, a feature that circumvents the problem of poor charge transport in low-mobility amorphous (or non-crystalline) detectors and enables them to achieve temporal performance similar to their high-mobility crystalline counterparts. Dr. Goldan has extensive experience in amorphous selenium (a-Se) devices and has co-invented, developed and fabricated a number of different direct and indirect detector technologies. He has successfully built the first a-Se UTD detector using the patented field-shaping multi-well technology and demonstrated more than two orders-of-magnitude improvement in temporal performance.
Dr. Goldan’s current research interest is combining UTD charge sensing and avalanche multiplication gain for (1) indirect a-Se detectors for time-of-flight PET, and (2) direct a-Se detectors for single photon counting digital mammography.
