ABSTRACT:
A collimator is provided for a scintillation camera system in which a detector precesses in an orbit about a patient. The collimator is designed to have high resolution and lower sensitivity with respect to radiation traveling in paths laying wholly within planes perpendicular to the cranial-caudal axis of the patient. The collimator has high sensitivity and lower resolution to radiation traveling in otherplanes. Variances in resolution and sensitivity are achieved by altering the length, spacing or thickness of the septa of the collimator.
