Variable slanted channel collimator

摘要

A collimator is disclosed which has a stack of radiation opaque plates that is tilted to vary the angle of view of the scintillation crystal of a radiation detector with respect to a radiation source. The plates have hexagonal apertures that are aligned with corresponding apertures on adjacent plates to provide radiation transmitting channels. As the stack is tilted, the plates slide laterally over one another to change the slant of the channels.
