Abstract

This invention relates to a method and an apparatus, primarily a radiation imaging apparatus and an array of coded aperture masks, for use in diagnostic nuclear medicine. The coded aperture masks are fitted with radiation attenuation tubes, each of which extends from each side of the mask in the direction of the mask apertures. The tubes are made from lead and have parallel sides. The masks are configured for gamma ray usage and are made from tungsten having a thickness of between 1 and 2 mm.
