A gamma ray collimator for use in a cardiac inspections system is disclosed which resolves energetically unperturbed gamma rays emitted from a patient and removes inelastic scattered gamma rays. A plurality of collimator elements each have walls, with each wall defining a plane comprised of a first material layer covered by a second material layer and absorbing inelastic scattered gamma rays, the planes being parallel to a central longitudinal axis in each of the collimator elements. The walls of each collimator element define an elongated longitudinal passageway having open ends through which the energetically unperturbed gamma rays enter and leave. The first material layer has a large absorption coefficient for gamma rays, and the second material layer has a large absorption coefficient for inelastically scattered gamma rays generated in the first material layer responsive to gamma rays emitted from the patient.

Radionuclide angiographic collimator system

A collimator assembly for removing selected radiation output from a specimen. The assembly includes collimator elements with each element having walls comprised of a first material covered by an inner layer of a second material which preferentially absorbs inelastic scattered radiation created in the first material.

Radiation collimator system

A method and apparatus for motion correction of image information collected by a cardiology inspection system. The cardiology inspection system collects image information from an exercising patient. The system corrects for the patient motion to provide dynamic time segmented images of radioactive dye flow through the patient's cardiac system, removing anomalous displacements from the images and allowing unambiguous evaluation of heart functionality while under physical stress.
