Dr. Sadek Nehmeh’s work in respiratory motion correction in combined positron emission tomography (PET)/computed tomography (CT) images was the first worldwide. He developed multiple methodologies to correct for breathing-induced artifacts, and his work on motion correction in PET/CT was awarded research grants from the National Institutes of Health (NIH) and General Electric (GE) Medical Systems. By enhancing PET image quality, Dr. Nehmeh improved predictive value in the thorax, specifically in the thorax of lung patients undergoing stereotactic radiosurgery and radiotherapy.
