ABSTRACT:
A large area X-ray image capture element is fabricated by juxtaposing a plurality of discrete array modules in an assembly over the top surface of a base plate, such that each module is disposed adjacent at least one other module to form a two-dimensional mosaic of modules. Each of the discrete modules includes a plurality of thin-form transistors arrayed adjacent the top surface of a dielectric substrate wherein at least one precision-ground edge forms a precise abutment with a precision-ground edge of another substrate. A continuous radiation detecting layer is disposed over the plurality of juxtaposed modules, and produces a latent radiographic image in the form of electrical charges. Such a method minimizes or totally voids the non-radiation-detecting areas created at the borders between the array modules.
