Composite segment collimators for SPECT without dead zones

摘要

A multi-view composite collimator includes a first parallel collimator segment having a plurality of collimator channels oriented at a first slant angle and a second parallel collimator segment adjacent to the first parallel collimator segment having a plurality of collimator channels oriented at a second slant angle different from the first slant angle and a bridging collimating element is provided between the first and second parallel collimator segments, wherein radiation can pass through the bridging collimating element.
