Research interests

Dr Tsoumpas interests revolve around the research methodology for quantitative Positron Emission Tomography (PET). He is passionate in pioneering the development of human molecular imaging with PET for the creation of cutting edge technologies that will significantly evolve clinical research and healthcare in several fields of Biomedicine.

Recent Projects

Four years Royal Society Industry Fellowship to work with Invicro (now part of Konica Minolta) on Novel Reconstruction Algorithms.

VIVOIMAG: Multimodal imaging of the in vivo fate of bone transplants. A European Horizon 2020 Marie Sklodowska-Curie Action Research & Innovation Staff Exchange project.

STIR: Software for Tomographic Image Reconstruction: This is the most widely used open access software for PET image reconstruction. Its main publication, Thielemans, Tsoumpas, et al (2012), received the 2017 Rotblat Medal as the most cited research paper published by Physics in Medicine & Biology (IOP & IPEM) out of more than 3,000 articles since 2012. Dr Tsoumpas is co-administrator and member of the development team. He co-organises an annual User's meeting during the IEEE Medical Imaging Conference. 

Cardiovascular PET-MR Imaging: This is an area of research led by Professor Zahi A. Fayad, Director of the Translational & Molecular Imaging Institute, the Icahn School of Medicine at Mount Sinai in New York, where Dr Tsoumpas holds a visiting academic appointment on PET-MR quantification to support a 5-years NIH grant.

CCP-PET-MR: Dr Tsoumpas is a Working Group Member of this collaborative computational project which aims at developing a platform for synergistic PET-MR reconstruction. In addition, Dr Tsoumpas is Co-investigator of a recently awarded Flagship Project which aims to develop a framework for efficient synergistic spatiotemporal reconstruction of PET-MR dynamic data. He co-organises Training Schools and Workshops on this theme. Both projects are led by Dr Kris Thielemans (UCL) and funded by EPSRC.

SAFIR: An active collaboration led by ETH Zurich which aims to building an innovative, high rate PET insert for MRI to be used for quantitative dynamic small animal imaging inside the bore of a commercial 7T MRI preclinical Bruker 70/30 scanner at the University Zurich. The project targets an unprecedented temporal resolution (about 5 seconds) and truly simultaneous PET/MR acquisition.

Crystal Clear: An active international academic research collaboration initiated and managed at CERN. Among many research areas it is involved in the research and development of novel materials for medical imaging.

FAST TD1401 COST Action: FAST aims to establish an interdisciplinary network that brings together experts from different fields of interest in order to develop photon instrumentation with an unparalleled timing precision of less than 100 ps. Dr Tsoumpas is the UK member of the Management Committee and of the Core Group as coordinator of the dissemination and outreach activities.
