Abstract
A gamma camera of the invention fitted with a pin-hole cone for acquiring photographic type images, i.e. having a tungsten end fitting disposed at the small end of a truncated cone and provided with a pin-hole therethrough, is suitable for forming a point image of an object to be observed on the basis of gamma radiation emitted therefrom, transmitted through the pin-hole and magnified on reaching the inlet to the scintillator. The truncated cone is modular in structure: the pin-hole cone is mainly constituted by a base, a first truncated cone of suitable thickness for stopping low energy gamma radiation, and a second truncated cone superposable at will on the first so that the assembled cones are of sufficient thickness to stop high energy gamma radiation.
