Brian Hutton is Professor of Medical Physics in Nuclear Medicine and Molecular Imaging Science at the Institute of Nuclear Medicine, University College London (UCL) and also holds a part-time appointment in Medical Radiation Physics at University of Wollongong, NSW, Australia. He has worked in Nuclear Medicine since 1975, originally based in teaching hospitals of the University of Sydney, where he published extensively, particularly in the areas of image processing and reconstruction for emission tomography (PET and SPECT). He currently leads a research group at the Institute of Nuclear Medicine at UCL with emphasis on SPECT system design, reconstruction in emission tomography and image processing to enable quantification in multi-modality imaging, including SPECT/CT, PET/CT and PET/MR. He has published more than 200 papers in peer reviewed journals and conference proceedings and 15 book chapters. He is also one of the developers of the IAEA Distance Assisted Training programme for Nuclear Medicine Professionals and continues to assist with its coordination. He was co-recipient of the 2014 IEEE Marie Sklodowska-Curie Award in recognition of his role in development of maximum likelihood reconstruction leading to its widespread and effective use in healthcare.
