  Profile
 

Andrew Todd-Pokropek is currently Professor of Medical Physics, a joint post created at University College London (Dept. of Medical Physics) and the Institute of Child Health (Physics and Radiology), and Director of the Research Unit U494 of the French Medical Research Organisation INSERM. As an undergraduate he read Physics at the University of Oxford. His first post was (as Assistant Lecturer 1964-1972) at the Institute of Nuclear Medicine, The Middlesex Hospital Medical School where he undertook his postgraduate studies. He assisting in the then rapid development of nuclear medicine instrumentation, was involved in the development of one of the first computer systems for use in medical imaging, and participated in the design of the first SPECT system in Europe. In 1972 he spent a sabbatical year at the Institut Gustave Roussy in France (and has maintained his 'French connection' up to the present date). He returned to London to take up a post as Senior Lecturer at the then University College Hospital Medical School, which eventually become part of University College London. He was appointed Reader in 1989 and Professor in 1993. Although he started his professional life in the area of nuclear medicine (in the basement running a whole body counter) he has become increasingly involved with medical image processing and data handling, firstly in nuclear medicine (for example in scatter and attenuation correction) and latterly in radiology in general. His areas of research extend from finding solutions for inverse problems to defining standards for medical image transfer (in particular for nuclear medicine) to developing expert systems for use in medicine. He has widely published and been invited to lecture by many different national and international organizations.

The Quantitative Medical Imaging group (previously known as the Medical Image Processing group), is a joint group established at University College London and also at the La Pitie Hospital in Paris where it is funded as INSERM unit U494, both parts under the direction of Professor Andrew Todd-Pokropek. The main research aims of this group, which now totals over 40 part and full time staff members, is the extraction of numerical data and information from the analysis of medical images of all types but in particular CT, MR, Nuclear Medicine and Ultrasound. The group has been awarded a number of grants from EPSCR, the Department of Health, HEFCE (Computer Board), the European Union (Telematics), the European Standardisation Body (CEN), the International Atomic Energy Agency (IAEA), the Special Trustees of University and the Middlesex Hospitals, INSERM, and in addition from various companies. These research projects have resulted in patents and software which is used for a number of clinical applications, for example the Portable Image Processing package, developed with the aid of the IAEA is now used by almost 200 hospitals in over 40 countries. The use of Factor Analysis in medical imaging (jointly developed at UCL and in Paris) has been incorporated into 3 commercial products and has recently been extended for use in MRI and functional MRI. The application of wavelets to data compression is another joint research program and was funded by Alliance (British Council and France). Image registration and fusion including 3D display has been another important area of research. The long history of research into the application of digital methods in medical imaging has resulted in a number of honours being awarded to Professor Todd-Pokropek including the American Society of Nuclear Medicine Annual Lecturership, the Sylvanus Thompson medal and the Normal Veale medal.
