Compton imaging is a promising imaging modality for radioactive contamination in nuclear
facilities. However, most of the Compton cameras in nuclear applications have been …

We report the development of a gamma-ray imaging device, named Large-Area Hybrid
Gamma Imager (LAHGI), featuring high imaging sensitivity and good imaging resolution …

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 …

Abstracts Compton cameras using large scintillators have been developed for high imaging
sensitivity. These scintillator-based Compton cameras, however, mainly due to relatively low …

A system consisting of a gamma camera and a collimator is used to measure the location of
a radiation source in a space where people use it or in places where people are crowded …

In the present study, a large-area hybrid gamma imaging system was designed by adopting
coded aperture imaging on the basis of a large-area Compton camera to achieve high …

Gamma cameras are often used to detect and locate radiation sources. A gamma camera
can acquire a 2D image to track the planar position. The use of a pinhole collimator or …

A system for measuring the position of a radiation source using a radiation spectroscopy
detector and maximum likelihood position estimation (MLPE) was designed. Three radiation …

For detector of a radiation source, a system for radiation positioning using radiation
spectroscopy detectors was constructed. This method can be used to measure a two …

When decommissioning large facilities such as cyclotrons or nuclear power plants, it is
essential to reduce the disposal costs of radioactive waste. For this, the massive materials …
