This chapter introduces an application case of self-organizing feature map (SOFM) on event processing of Positron Emission Tomagraph (PET) detector. The Siemens Inveon Dedicated PET scanner uses an array of 64 20x20 segmented LSO detectors in a tomographic arrangement to allow PET imaging of small animals. A detector consists of 20x20 LSO crystal pixels coupled to a Position Sensitive Photomult...

introduction: the mechanism of action and metabolism of clozapine, a complex drug used in psychopharmacology, is not completely understood. the effects of this compound in human body are related to some interactions with serotonin and dopamine neurotransmitter receptors. to further elucidate the mechanism of action and to support ongoing drug metabolism studies, [14c] clozapine with suitable ra...

The detector in single-photon emission computed tomography has played a key role in the quality of the images. Over the past few decades, developments in semiconductor detector technology provided an appropriate substitution for scintillation detectors in terms of high sensitivity, better energy resolution, and also high spatial resolution. One of the considered detectors is cadmium telluride (...

Data taken by CRESST in 2000 with a cryogenic detector system based on 262 g sapphire crystals is used to place limits on WIMP dark matter in the Galactic Halo. The detector is especially sensitive for low-mass WIMPS with spin-dependent cross sections and improves on existing limits in this region. CRESST is now preparing for a second phase, which will use a 10 kg detector consisting of 300 g C...

X-ray photon correlation spectroscopy (XPCS) provides an opportunity to study the dynamics of systems by measuring the temporal fluctuations in a far-field diffraction pattern. A two-dimensional detector system has been developed to investigate fluctuations in the frequency range of several Hz to kHz. The X-ray detector system consists of a thin 100 microm scintillation crystal coupled to a Gei...

MACRO was a large multipurpose underground detector located in the Hall B of the Laboratori Nazionali del Gran Sasso. The detector, which took data until December 2000, was arranged in a modular structure of six “supermodules” with global dimensions of 76.5 × 12 × 9.3m and a total acceptance of ∼ 10, 000 msr to an isotropic flux of particles. It was made by several layers of liquid scintillatio...
