Abstract
Abstract ABSTRACT A nuclear imaging device comprising a plurality of scanning heads spaced apart in a predetermined configuration with the aid of a support member that permits the individual scanning heads to scan in parallel, anti-parallel, and tomographic modes. The support member which is driven in both X and Y directions in mechanically connected with the stylus of a graphical X-Y plottervia a backlash linkage. Displays are provide wherein the color of the ink dot on printed paper or the intensity of the light projected on photographic film are related to the nuclear particle count in a preselectable manner.
