Abstract
Abstract A gamma camera (1), has a scintillation block with an entrance window (10) constituted by a mechanically stiff supporting structure which very slightly absorbs X and gamma rays. The entrance window (10) supporting the scintillation block (3) may be constituted by a honeycomb structure of a light material.
