One direct way to improve the gamma camera's sensitivity is using large-area gamma
detectors. During construction of a large-area gamma camera, achieving high uniformity …

Organic semiconductor radiation detectors have been developed using conductive polymers
as sensor materials. Unlike the commonly used inorganic semiconductor detectors, the use …

We introduce a novel gamma-ray imaging technique that uses detector response patterns.
This method employs multiple shielding cubes randomly positioned in a three-dimensional …

High spatial resolution is of great significance for the γ-ray imaging technique, whose
performance is mainly limited by the spatial resolution of position sensitive detectors (PSDs) …

In this article, we present a new industrial gamma-ray imaging system. This system takes
advantage of a time-modulated random coded aperture (TMRCA). The gamma-ray detector …

When gamma-camera sensor modules, which are key components of radiation imagers, are
derived from the coupling between scintillators and photosensors, the light collection …

The pinhole gamma camera is a simple and useful device for determining the radiation
distribution in a certain region. Using this device, we developed a method to measure the …

Gamma-ray imaging is a technique for visualizing the spatial distribution of radioactive
materials. Gamma-ray imaging has recently been applied to research on environmental …

A novel direction-sensitive gamma ray detector is developed based on attenuation. The
detector consists of 30 GAGG: Ce scintillators (2× 2× 20 mm 3) closely arranged around a …

The number of nuclear facilities being decommissioned has been increasing worldwide, in
particular following the accident of the Tokyo Electric Power Company Holdings' Fukushima …
