SCINTILLATOR BASED DETECTION APPARATUS AND METHOD USING TWO-DIMENSIONAL MATRIX OF LIGHT DETECTING ELEMENTS

摘要

An radiation detector comprises a scintillating layer (3); a radiation entrance (9); and a light detection arrangement (16) including a two-dimensional matrix of light detecting elements (17), wherein the light detection arrangement is oriented with respect to the radiation entrance such that light (25), being emitted in the scintillating layer in a direction essentially perpendicular to the direction at which the radiation beam is entered into the scintillating layer, is detectable. Further, a grid-like layer (13) including a plurality of light-transparent openings (15) is arranged between the scintillating layer and the light detection arrangement and aligned therewith, such that the respective light-transparent openings (15) are overlying the respective light detecting elements (17).
