Abstract
A medical imaging tool is described, capable of providing in real time 2-D images of the prompt gamma fields released during patient treatment. Owing to its millimetre position accuracy, the instrument is particularly suited for applications where a precise determination of the end-of-range (Bragg peak) of the beam is of paramount importance, as in cancerous and non-cancerous targets for treatment with ion beams and for the treatment of atrial fibrillation. With its unique dual-layer conception in coincidence, the instrument has high rejection ability against false neutron-generated counts, the principal source of background noise for in-beam dose monitoring. It can also provide a coarse measurement of the gamma incidence angle, permitting a correction of the parallax error, main source of dispersion for large area detectors employing collimators.
