A RADIATION IMAGING DEVICE WITH IRREGULAR RECTANGULAR SHAPE AND EXTRAORAL DENTAL IMAGING SYSTEM THEREFROM

摘要

A radiation imaging device comprises a plurality of individual detectors (13) positioned adjacently and defining an active area responsive to x-rays. Each of the individual detectors has a rectangular shape and they define together an overall active area with a length y and a width x. The device comprises at least one detector module on which said individual detectors are mounted. The individual detectors comprise at least two individual Cd(Zn)Te detectors juxtaposed next to each other with an average physical gap (14) of at least 0.005 mm between the outside-most edges of the Cd(Zn)Te detectors.
