Nguyen, M.P. (author), Goorden, M.C. (author), Beekman, F.J. (author)We recently developed a dedicated focusing multi-pinhole collimator for a stationary SPECT system that offers down to 120 m (or 1.7 nL) spatial resolution SPECT images of cryo-cooled tissue samples (EXIRAD-3D). This collimator is suitable for imaging isotopes that are often used in small animal and diagnostic SPECT such as 125I (27 keV),...journal article 2020

Ozsahin, Ilker (author), Chen, Ling (author), Könik, Arda (author), King, Michael A. (author), Beekman, F.J. (author), Mok, Greta S.P. (author)Single photon emission computed tomography (SPECT) is an important imaging modality for various applications in nuclear medicine. The use of multi-pinhole (MPH) collimators can provide superior resolution-sensitivity trade-off when imaging small field-of-view compared to conventional parallel-hole and fan-beam collimators. Besides the very...review 2020

Branderhorst, W. (author), Vastenhouw, B. (author), Van der Have, F. (author), Blezer, E.L.A. (author), Bleeker, W.K. (author), Beekman, F.J. (author)Purpose: Small-animal single photon emission computed tomography (SPECT) with focused multi-pinhole collimation geometries allows scanning modes in which large amounts of photons can be collected from specific volumes of interest. Here we present new tools that improve targeted imaging of specific organs and tumours, and validate the effects of...journal article 2010
