The use of monolithic scintillator-based photon detectors in positron emission tomography
(PET) has emerged as an attractive alternative to traditional pixelated array designs …

We investigate five different models to reconstruct the 3D γ-ray hit coordinates in five large
LaCl 3 (Ce) monolithic crystals optically coupled to pixelated silicon photomultipliers. These …

The ideal contribution factor of a PM is a function of the two dimensional coordinate (x, y) of
a scintilla tion point. However, it is very difficult to realize such a position computer by a …

Achieved spatial resolution of the PET systems is often limited by the parallax error due to
the lack of information about the Depth of Interaction (DoI) inside the crystal of the incoming …

Over the last 3 years, there has been a growing interest in the development of a new class of
fast scintillators such as LaCl3: Ce and LaBr3: Ce. Their superior energy resolution is …

An iterative position-weighted centre-of-gravity algorithm was developed and tested for
positioning events in a silicon photomultiplier (SiPM)-based scintillation detector for positron …

In this work, we present a mean square estimation (MSE) based algorithm to calculate the
position of a scintillation event within the crystal of a gamma camera dedicated to single …

Many modern molecular imaging techniques, based on radiopharmaceuticals, can take
advantage of sophisticated devices but are still based on the scintillation detector …

Although the technological advances in hardware of gamma camera lead to an obvious
increase of detector performance, the final reconstructed image is still strongly restricted by …

The use of position sensitive photomultiplier tubes (PSPMT) in Nuclear Medicine imaging
has recently produced some major steps forward in this field. In fact a dedicated camera for …
