The prize is in recognition of Kalender's achievements in developing, testing and establishing spiral CT - a technology that's enabled the transition from two-dimensional CT imaging to fast volumetric three-dimensional imaging and which is now fully integrated into clinical practice.

"I am overwhelmed and truly happy," said Kalender. "Medical imaging has gotten quite a bit of attention in recent years. It is generally acknowledged that the advances in 3D imaging with different modalities such as CT, MR, PET and ultrasound has brought remarkable and practically relevant progress for diagnostic and therapeutic procedures."

Kalender's main area of research is diagnostic imaging, with a focus on volumetric spiral CT. His other interests include radiation protection and the development of quantitative diagnostic procedures, to assess osteoporosis, lung and cardiac diseases, for example.

Financed by the Geneva-based Latsis Foundation, the prize is presented each year to a scientist or research group in recognition of outstanding and innovative contributions in a selected field of research. "I hope that the award of the European Latsis Prize in 2007 to work in medical imaging will have a further positive effect on this field of research," said Kalender.

• At the Radiological Society of North America (RSNA) annual meeting, held last week in Chicago, IL, radiation physicist William R Hendee received the RSNA Gold Medal. The award was presented in recognition of Hendee's "important and wide-ranging contributions" to medical physics, diagnostic radiology, radiation oncology and biomedical engineering. Hendee is a distinguished professor of radiology, radiation oncology, biophysics and community and public health at the Medical College of Wisconsin (Milwaukee, WI).
