Abstract
An apparatus for providing electrical signals representative of an image formed by X-rays projected thereon includes a two-dimensional array of spaced apart light sensitive sensors formed from deposited semiconductor material. The elements are capable of effecting a detectable electrical characteristic responsive to the intensity of light received thereon. A phosphorescent layer overlying the light sensitive elements receives the projected X-ray image and produces light in response to the impingement of the X-rays thereon. Isolation elements enable the selective addressing of the light sensitive elements. A method of converting an image from electromagnetic energy to a plurality of electrical signals is also disclosed.
