  • Image capture device using a secondary electrode
    Patent number: 5895936
    Abstract: An image capture panel particularly useful in radiographic application is disclosed, in which the active image capture area of individual sensors having top and bottom charge collecting microplates arrayed in rows and columns is extended by providing an additional charge capture conductive strip over sensor areas which are not normally covered by a charge collecting microplate. The strip may be made integral with the top microplate or may be separate and electrically connected thereto at a single point.

  • Method for preparing digital radiography panels
    Patent number: 5844243
    Abstract: A method for preparing X-ray image capture panels suitable for use in digital, radiography is disclosed. Array modules with sharp, steep edges suitable for tiling to form X-ray image capture panels are prepared placing an array module against an edge piece, and vacuum depositing a radiation detecting material on the top surface of the array module and the edge piece while simultaneously moving at least one of them relative to the other in the horizontal and/or the vertical direction.
