Development of Large area Gamma-ray Camera with GSO(Ce) Scintillator Arrays and PSPMTs [PDF]

, 2006
We have developed a position-sensitive scintillation camera with a large area absorber for use as an advanced Compton gamma-ray camera. At first we tested GSO(Ce) crystals.

Compton Camera Arrangement With a Monolithic LaBr3(Ce) Scintillator and Pixelated GAGG Detector for Medical Imaging

IEEE Transactions on Radiation and Plasma Medical Sciences, 2023
The results presented in this manuscript are divided in two main parts. The aim of the presented work is to conduct feasibility tests on a Compton camera setup to be later scaled up and used for PET and triple coincidence $\gamma $ -PET purposes.

HESS J1632-478: an energetic relic [PDF]

, 2010
HESS J1632-478 is an extended and still unidentified TeV source in the galactic plane. In order to identify the source of the very high energy emission and to constrain its spectral energy distribution, we used a deep observation of the field obtained ...

CCMod: a GATE module for Compton camera imaging simulation [PDF]

Physics in Medicine & Biology, 2020
Abstract Compton cameras are gamma-ray imaging systems which have been proposed for a wide variety of applications such as medical imaging, nuclear decommissioning or homeland security. In the design and optimization of such a system Monte Carlo simulations play an essential role.

Evaluation of a CdTe semiconductor-based gamma camera for real-time dose dosimetry in boron neutron capture therapy. [PDF]

Med Phys
Abstract Background Boron neutron capture therapy (BNCT) is a cancer treatment that leverages the nuclear reaction between boron‐10 (10B$^{10}{\rm B}$) and thermal neutrons to generate high‐energy α$\alpha$ particles and 7Li$^{7}{\rm Li}$ nuclei that selectively destroy cancer cells while sparing healthy tissues.

Radioisotopic purity and imaging properties of cyclotron-produced 99mTc using direct 100Mo(p,2n) reaction [PDF]

, 2018
Evaluation of the radioisotopic purity of technetium-99m (99mTc) produced in GBq amounts by proton bombardment of enriched molibdenum-100 (100Mo) metallic targets at low proton energies (i.e. within 15\u201320 MeV) is conducted.

Bin mode estimation methods for Compton camera imaging [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2014
We study the image reconstruction problem of a Compton camera which consists of semiconductor detectors. The image reconstruction is formulated as a statistical estimation problem. We employ a bin-mode estimation (BME) and extend an existing framework to a Compton camera with multiple scatterers and absorbers. Two estimation algorithms are proposed: an

New readout and data-acquisition system in an electron-tracking Compton camera for MeV gamma-ray astronomy (SMILE-II) [PDF]

, 2015
For MeV gamma-ray astronomy, we have developed an electron-tracking Compton camera (ETCC) as a MeV gamma-ray telescope capable of rejecting the radiation background and attaining the high sensitivity of near 1 mCrab in space. Our ETCC comprises a gaseous
