Abstract: A flexible digital radiographic detector assembly uses a conformable bag having granular media therein to enclose the detector and to help fit the detector onto a curved object. The conformable bag is evacuated to hold the detector against the object to be imaged. An image of the object is acquired by aiming x-rays through the object toward the detector.

Abstract: A digital radiographic image sensor includes a flexible first substrate with an image sensor array. A scintillator is formed over the array, and bonding pads in a peripheral region outside the array are connected to the array. A second substrate is attached to a bottom of the first substrate and includes a scribed or perforated break line to enable removal of a peripheral region of the second substrate.
