Abstract
A nuclear imaging system in which a substantially on-axis Fresnel zone plate positioned between a source of nuclear radiation in living tissue and a spatial detector is moved in a predetermined time sequence in synchronism with motion of a bar pattern formed at the spatial detector output to improve suppression of unwanted spatial frequency components and to facilitate production of an image of the nuclear source.
