Background contributions in the electron-tracking Compton camera aboard SMILE- 2+ [PDF]

open access: yesPhysical Review D, 2023
The Mega electron volt (MeV) gamma-ray observation is a promising diagnostic tool for observing the universe. However, the sensitivity of MeV gamma-ray telescopes is limited due to peculiar backgrounds, restricting the application of MeV gamma rays for ...

Compton sequence estimation based on the deep learning method

open access: yesAIP Advances, 2022
Determining the sequence of Compton scattering and photoelectric absorption events for a Compton camera system through timing information is difficult due to the finite timing resolution of radiation detectors.

An Electron-Tracking Compton Telescope for a Survey of the Deep Universe by MeV gamma-rays [PDF]

open access: yes, 2015
Photon imaging for MeV gammas has serious difficulties due to huge backgrounds and unclearness in images, which are originated from incompleteness in determining the physical parameters of Compton scattering in detection, e.g., lack of the directional ...

A New Compton Camera Imaging Model to Mitigate the Finite Spatial Resolution of Detectors and New Camera Designs for Implementation

open access: yesTechnologies, 2015
An intrinsic limitation of the accuracy that can be achieved with Compton cameras results from the inevitable fact that the detectors, which comprise the camera, cannot have infinitely-accurate spatial resolution. To mitigate this loss of accuracy, a new
