Schaart, D.R. (author), Van Dam, H.T. (author), Seifert, S. (author), Vinke, R. (author), Dendooven, P. (author), Löhner, H. (author), Beekman, F.J. (author)Silicon photomultipliers (SiPMs) are of great interest to positron emission tomography (PET), as they enable new detector geometries, for e.g., depth-of-interaction (DOI) determination, are MR compatible, and offer faster response and higher gain than other solid-state photosensors such as avalanche photodiodes. Here we present a novel detector...journal article 2009

Maas, M.C. (author), Schaart, D.C. (author), Van der Laan, D.J. (author), Bruyndonckx, P. (author), Lemaître, C. (author), Beekman, F.J. (author), Van Eijk, C.W.E. (author)We developed positron emission tomography (PET) detectors based on monolithic scintillation crystals and position-sensitive light sensors. Intrinsic depth-of-interaction (DOI) correction is achieved by deriving the entry points of annihilation photons on the front surface of the crystal from the light sensor signals. Here we characterize the...journal article 2009

Korevaar, M.A.N. (author), Heemskerk, J.W.T. (author), Goorden, M.C. (author), Beekman, F.J. (author)Gamma cameras based on charge-coupled devices (CCDs) and micro-columnar CsI scintillators can reach high spatial resolutions. However, the gamma interaction probability of these scintillators is low (typically <30% at 141 keV) due to the limited thickness of presently available micro-columnar scintillators. Continuous scintillators can improve...journal article 2009
