The history of Compton cameras began with the detection of radiation sources originally for
applications in astronomy. A Compton camera is a promising γ-ray detector that operates in …

Compton imaging exploits inelastic scattering, known as Compton scattering, using a
Compton camera consisting of a scatterer detector in the front layer and an absorber …

Imaging of nuclear gamma-ray lines in the 1–10 MeV range is far from being established in
both medical and physical applications. In proton therapy, 4.4 MeV gamma rays are emitted …

We have been developing a medical imaging system using a Compton camera and
demonstrated the imaging ability of Compton camera for 99mTc-DMSA accumulated in rat …

Considerable amounts of radioactive substances (mainly 137 Cs and 134 Cs) were
released into the environment after the Japanese nuclear disaster in 2011. Some restrictions …

Since the discovery of nuclear gamma-rays, its imaging has been limited to pseudo imaging,
such as Compton Camera (CC) and coded mask. Pseudo imaging does not keep physical …

Astatine-211 is a promising radionuclide for targeted radiotherapy. It is required to image the
distribution of targeted radiotherapeutic agents in a patient's body for optimization of …

A compact, portable and large field-of-view gamma camera that is able to identify, locate and
quantify gamma-ray emitting radioisotopes in real-time has been developed. The device …

To propose a novel monitoring method for the quantitative visualization of 3D distribution of
a radioactive plume in the vicinity of release point and source term estimation of released …

Compton telescopes rely on the dominant interaction mechanism in the MeV gamma-ray
energy range: Compton scattering. By precisely recording the position and energy of …
