Helmar Bergmann is Professor Emeritus of Clinical Physics. He was director of the Department of Biomedical Engineering and Physics from 1993 to 2004, then director of the Center of Medical Physics and Biomedical Engineering until 2009.
He studied physics and mathematics at Vienna University and graduated with a PhD in experimental nuclear physics (1970). He worked at the Division of Nuclear Medicine of the 2nd Department of Internal Medicine, Medical Faculty, University of Vienna (1970 - 1991) where he was responsible for the management of the instrumentation. Research included quantitative digital scintigraphy, especially studies related to the staging of brain tumours, and regional thyroid uptake studies.
In connection with his design and implementation of a shadow shield whole body counter in Vienna he spent a year as a Research Fellow of the Wellcome Trust at the Royal Marsden Hospital, Sutton (1973/74) and with a British Council postgraduate grant at the Medical Physics Dept. of the Royal Infirmary, Edinburgh (1976), in connection with research in low level radioactivity profile scanning and its applications in rheumatology.
Since 1979 he participated in Advisory Group and Consultants Meetings of the IAEA and the WHO and carried out several expert missions on behalf of the IAEA in various parts of the world, with the general topics Quality Assurance in Nuclear Medicine and Digital Scintigraphy. Research concentrated then on quality control of nuclear medicine instrumentation, especially for gamma cameras and quality control of SPECT systems. Further areas of research are gastric motility, factor analysis in co-operation with Dr. M. Samal from Charles University Prague, networks in nuclear medicine, and image guided therapy.
In 1992 he was appointed Professor of Clinical Physics and became a staff member of the Department of Biomedical Engineering and Physics of the Medical Faculty of the University of Vienna. In 1993, he was elected director of the department.
From 1972 to 2012, Helmar Bergmann has participated in the organisation of the biannual international symposia "Radioactive Isotopes in Clinical Medicine and Research", and was editor of the Congress Proceedings, up to now 21 volumes, jointly with professor R. Höfer and his successors. In 1987 he organised the 2nd European EFOMP Scientific Conference jointly with the Austrian and German Societies of Medical Physics. He was the European editor on the editorial board of "Physics in Medicine and Biology" (1988-1993), member of the editorial boards of the "Zeitschrift für Medizinische Physik" (1997-2000), of the "European Journal of Nuclear Medicine" (1993 - 2012), of the "ALASBIMN Journal", of the international editorial board of the "Revista Española de Medicina Nuclear" (1999 - 2015) and of the consulting editorial board of the "Zeitschrift für Medizinische Physik" (2001 - 2012).
