Adaptive imaging using a Rotating Modulation Collimator (RMC)

The Rotating Modulation Collimator (RMC) is a simple radiation imaging system that can be operated with as little as a single non-position sensitive radiation detector. While simple, its detection efficiency suffers due to necessary collimation of the incoming radiation. This paper explores adaptive techniques aimed at improving the detection efficiency and image quality for a given RMC system. Specifically, the collimating mask design, the sampling technique, and the RMC pivot angle are explored.
