Add to ORKGCone-beam collimators provide increased sensitivity at similar res olution compared to other collimators. The use of cone-beam collimators for brain imaging with triple-camera SPECT systems, however, results in truncation of the base of the brain because of clearance of the shoulders. A half-cone beam collimator does not have the problem of truncation. The objective of this study was to compare the performance characteristics of half-cone beam with parallel-beam and fan-beam collimators with similar resolution char acteristics for SPECT imaging of the brain. Methods: A half-cone beam collimator with the focal point located towards the base of the brain was built for a triple-camera SPECT system. Spatial resolu tions and sensitivities of thr...
