Development of VRAIN: The Worldʼs First Hemispherical Brain PET

Abstract

What is the ideal brain-dedicated PET system? Our answer to this question is a hemispherical detector arrangement. This geometry, which may fit the head the best, improves the spatial resolution as well as the sensitivity without increasing the number of detectors. After seven years of research and development, we developed the worldʼs first hemispherical brain PET “VRAIN”. A sitting style is also a major feature of VRAIN, which may improve patient comfort. A reduced footprint could help hospitals save space.
