Abstract
A rotating laminar emission camera includes a detector ( ) which detects radiation. The detector ( ) has a radiation receiving side ( ) that faces an object (e.g., a patient ) being studied. The detector ( ) includes an array of detection elements ( ), the array extending in a first direction across the radiation receiving side ( ) of the detector ( ). The detection elements ( ) each individually detect radiation incident thereon. A collimator ( ) constructed of a radiation attenuative material is arranged on the radiation receiving side ( ) of the detector ( ). The collimator ( ) experiences relative rotation about an axis ( ) substantially normal to the radiation receiving side ( ) of the detector ( ). The relative rotation is relative to the object being studied. The collimator ( ) includes a plurality of spaced apart slats ( ) each extending in a second direction across the radiation receiving side ( ) of the detector ( ). The slats ( ) are spaced apart from one another such that a plurality of the detector elements ( ) in the array thereof are arranged between adjacent pairs of slats ( ).
