title: I-123 HIPDM brain imaging with a rotating gamma camera and slant-hole collimator.
abstract: The performance of a slant-hole collimator was compared with that of a standard straight-bore, low-energy collimator for tomographic imaging of I-123-iodinated amine brain agents. Improved in-slice resolution was due to the greater proximity between collimator and the subjects' heads. We conclude that high quality tomographic images of the brain can be obtained from rotating cameras equipped with slant-hole collimators.
