Nikolaos Efthymiou, PhD

Nikos Efthimiou is an Instructor at the Athinoula A. Martinos Center for Biomedical Research with more than ten years of experience in Medical Imaging, focusing on Positron Emission Tomography. Nikos' expertise spans detector technologies such as Silicon Photomultipliers, front-end electronics, system and detector modeling, statistical image reconstruction, absolute quantification, motion, and scatter correction. Thanks to his interdisciplinary background, he has a successful record of accomplishments in academia. In his current position, Nikos investigates synergistic motion and attenuation correction in PET/MR scanners. Also, has developed energy-based scatter correction algorithms for Long Axial FOV PET scanners. Also, he has explored other emerging technological challenges, such as BGO-Cherenkov detectors for PET scanners. Nikos has lived in three countries and speaks English and Greek. His colleagues describe him as analytical, thorough, committed, and hard-working.
