Maximum likelihood reconstructions for rotating scatter mask imaging

Dual-Particle Imaging Performance of a Cs2LiYCl6:Ce (CLYC)-Based Rotational Modulation Collimator (RMC) System

“…However, our RMC system allows easy replacement collimator masks and the radiation detector depending on its purpose [25]. Since any type of detectors such as 7 Li enriched CLYC (CLYC-7) and stilbene scintillator can be combined with the current system, it could be modified to a fast neutron imaging system [31][32][33]. Herein, more detailed considerations may have to be made to the collimators so that they can effectively scatter off incident fast neutrons away from its original direction.…”

“…However, typical dual-particle imaging systems are based on the Compton camera concept and coded aperture, which require position-sensitive radiation detectors [1][2][3]. One of recent advances in the radiation imaging system includes the development of a rotating scatter mask Hyun Suk Kim is with the Division of Radiation Regulation, Korea Institute of Nuclear Safety (KINS), Daejeon, Korea (RSM) system, which identifies the direction of the source with a single detector [4][5][6][7][8]. The system response is derived from primarily scattering events instead of full-energy absorption, as a function of time.…”
