A coded aperture gamma camera based on a novel imaging model which decomposes the
mask projections as a superposition of two separable functions was proposed for near-field …

Gamma-ray coded-aperture imaging technology plays an important role in nuclear security,
decommissioning of nuclear facilities, and nuclear medicine diagnosis. However, under …

Coded Aperture Imaging is a technique originally developed for X-ray astronomy, where
typical imaging problems are characterized by far-field geometry and an object made of …

The mask parameters of a coded aperture are critical design features when optimizing the
performance of a gamma-ray camera. In this paper, experiments and Monte Carlo …

In the 1990s, CEA has developed a very compact operational gamma camera, CARTOGAM,
capable of mapping the surrounding radioactivity and representing it superimposed onto a …

Coded-aperture gamma imaging techniques have been applied widely in several radiation
monitoring fields. However, in terms of the design of the coded-aperture mask, the category …

In the 1990's, CEA has developed one of the most compact operational gamma cameras in
the world, CARTOGAM, capable of mapping the surrounding radioactivity and representing …

There is an ever-growing need for instrumentation that provides both high-resolution and
sensitive volumetric gamma-ray imaging capabilities across a wide range of photon …

Coded aperture techniques based on a cyclic difference set uniformly redundant array
(URA) increase the sensitivity of an imaging system without degrading the spatial resolution …

Standard nuclear medicine imaging uses photon collimation and thus suffers from very low
sensitivity, especially if high energy (> 511 keV) isotopes are to be imaged. Coded aperture …
