Biography Dr. Visvikis
Dimitris Visvikis is a director of research with the National Institute of Health and Medical Research (INSERM) in France and a co-director of the Medical Image Processing Lab in Brest (LaTIM, UMR1101). He obtained his PhD from the University of London in 1996 working in PET detector development within the Joint Department of Physics in the Royal Marsden Hospital and the Institute of Cancer Research. After working as a Senior Research Fellow in the Wolfson Brain Imaging Centre of the University of Cambridge he joined the Institute of Nuclear Medicine as Principal Medical Physicist in University College London where he introduced and worked for five years with one of the first clinical PET/CT systems in the world. He has spent the majority of his scientific activity in the field of PET imaging, including developments in both hardware and software domains. His current research interests focus on improvement in PET/CT image quantitation for specific oncology applications, such as response to therapy and radiotherapy treatment planning, through the development of methodologies for detection and correction of respiratory motion, 4D PET image reconstruction, partial volume correction, tumour volume segmentation and tumour activity distribution characterisation algorithms, as well as the development and validation of Monte Carlo simulations for emission tomography and radiotherapy treatment dosimetry applications. He is a member of numerous professional societies such as IPEM (Fellow, Vice-President International), IEEE (Senior Member, NPSS NMISC chair), AAPM, SNM (CaIC board of directors 2007-2012), EANM.
