Method for preparing digital radiography panels

A module useful for assembling a large scale image capture panel, said module, comprising:

• a) a support having a top surface
• b) a plurality of image capture sensors on said support surface,
• c) at least one precision finished side in a plane substantially perpendicular to said support surface and
• d) a radiation detection layer comprising a radiation detecting material deposited on said support over said sensors by a process comprising:
• 1) placing the at least one precision finished side against a reference edge piece having a reference top surface and a reference side in a plane substantially perpendicular to the reference top surface, such that the module precision finished side and the reference side are substantially parallel, and
• 2) vacuum depositing the radiation detecting material on the top surfaces of said module and said reference piece while simultaneously moving at least one of said module and said reference piece relative to the other in a direction such that the module precision finished side and the reference side remain parallel and at a constant distance from each other.

A large image capture panel comprising:

• I) a base plate;
• and
• II) a plurality of modules on said base plate each of said modules comprising:
• a) a support having a top surface
• b) a plurality of image capture sensors on said support surface,
• c) at least one precision finished side in a plane substantially perpendicular to said support surface and
• d) a radiation detection layer deposited on said support over said sensors by a process comprising:
• 1) placing the at least one precision finished side against a reference edge piece having a reference top surface and a reference side in a plane substantially perpendicular to the reference top surface, such that the module precision finished side and the reference side are substantially parallel, and
• 2) vacuum depositing the radiation detection layer on the top surfaces of said module and said reference piece while simultaneously moving at least one of said module and said reference piece relative to each other in a direction such that the module precision finished side and the reference side remain substantially parallel and at a constant distance from each other;
• and
• e) a conductive top layer over said radiation detection layer;
• wherein the plurality of modules on the base plate are assembled on said base plate with each module having at least one precision finished side adjacent a precision finished side of another module.
