Arman Rahmim, Ph.D.
Chief Physicist, Section of High Resolution Brain PET Imaging, Division of Nuclear Medicine, Department of Radiology
Associate Professor of Radiology and Radiological Science
Dr. Arman Rahmim is an Associate Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science. Additionally, he serves as chief physicist in the Section of High Resolution Brain PET Imaging in the Division of Nuclear Medicine.
Dr. Rahmim received his M.S. in condensed matter physics and a Ph.D. in medical imaging physics from the University of British Columbia. His laboratory at the division of nuclear medicine pursues state-of-the-art tomographic image reconstruction and analysis methods that can assist in brain, cardiac and oncologic applications. He is a principal investigator or co-investigator on a number of grants focusing on enhanced quantitative imaging, with particular focus on translation to clinical imaging.
Dr. Rahmim also holds a joint appointment in the Johns Hopkins University Department of Electrical & Computer Engineering. He lectures for ECE/BME students as well as nuclear medicine residents and post-doctoral fellows.
Dr. Rahmim was elected as an IEEE Senior Member in 2012, and is a member of the Public Education Board at the American Association of Physicists in Medicine (AAPM), and the Computer and Instrumentation Council (CaIC) of the Society of Nuclear Medicine & Molecular Imaging (SNMMI).

Research & Publications
The Rahmim Lab pursues interdisciplinary research toward enhanced quantitative image generation and analysis for tomographic medical imaging devices (PET, SPECT, CT) including emphasis on multi-modality imaging (e.g., PET/MRI, PET/CT). Our lab has extensive experience and expertise with mathematical, computational and engineering tools to achieve state-of-the-art medical imaging, and we continue to lead collaborations with researchers in the areas of imaging physics/engineering, mathematics, computer science, radiochemistry, biological modeling and medicine. We aim to develop and validate novel solutions for medical device data acquisition, data correction, image reconstruction and quantification. We actively pursue and lead research on the three fronts of brain, cardiac and oncologic imaging, all aimed at robust and feasible quantitative imaging.
