Monte Carlo simulations play an important role in positron emission tomography (PET)
imaging, as an essential tool for the research and development of new scanners and for …

We have developed a new X-ray cone-beam tomograph for in vivo small-animal imaging
using a flat panel detector (CMOS technology with a microcolumnar CsI scintillator plate) …

Purpose: In the present work, the authors compare geometrical and Monte Carlo projectors
in detail. The geometrical projectors considered were the conventional geometrical Siddon …

In this work, we compare two commercial positron emission tomography (PET) scanners
installed at CIEMAT (Madrid, Spain): the ClearPET and the rPET-1. These systems have …

This work reports on the development and performance evaluation of the VrPET/CT, a new
multimodality scanner with coplanar geometry for in vivo rodent imaging. The scanner …

A fully 3D iterative image reconstruction algorithm has been developed for high-resolution
PET cameras composed of pixelated scintillator crystal arrays and rotating planar detectors …

Pile-up and dead-time are two main causes of nonlinearity in the response of a PET scanner
as a function of activity in the field of view (FOV). For a given scanner and acquisition …

A truncated icosahedron system with hexagonal detectors has been previously proposed as
an approach to the ideal spherical PET scanner. In this work, we explore by Monte Carlo …

We present the development of a new fully digital, flexible, cost-efficient data acquisition
system (DAQ) suitable for dual head Positron Emission Tomography (PET) scanners for …

Low‐pass filtering of sinograms in the radial direction is the most common practice to limit
noise amplification in filtered back projection (FBP) reconstruction of positron emission …
