In hadron therapy, prompt gamma rays are emitted during the treatment from the excited nuclei in the tissue, and can be employed for dose monitoring. A Compton telescope is under development within the ENVISION project for imaging the prompt gamma rays. The telescope will consist of several detector layers, each composed of a continuous LaBr3 crystal coupled to silicon photomultiplier (SiPM) arrays...
PET probes are showing a lot of promise in extending performance of the conventional PET ring. The underlying idea is to supplement basic PET data with information collected in the finely segmented probe placed close to the region of interest. The benefit is two fold: a) data collected near the object are less prone to errors related to scattering and acolinearity and b) the object itself is magnified...
The University of Pisa and INFN Pisa are developing a prototype of a small animal PET tomograph employing continuous LYSO crystals and silicon photomultiplier (SiPM) matrices as photodetectors. The Center for Scientific and Technological Research (FBK-irst) has developed monolithic, 64 pixel SiPM matrices for their use in the PET scanner. The IFIC-Valencia collaborates in the characterization of the...
Detection and spectroscopic tests of three self-triggered silicon detection modules constructed using Tape Automated Bonding and micro-cable technologies and equipped by VATA read-out chips are presented and compared. Results of these tests are demonstrated using hit maps and pulse-height spectra induced by 133Ba, 241Am, and 57Co radioactive sources of X- and gamma rays. We have observed significant...
Our group is developing a Compton camera [Clinthorne, N, 2006] for medical imaging. Most camera incarnations envision the scatterer as a set of thick silicon pad detectors, and the absorber as a conventional NaI scintillator camera. High single detector countrates are expected in both sub-detectors, requiring good timing resolution in both detectors. For this paper the timing properties of currently...
