Apparatus and methods for high performance radiographic imaging array including reflective capability

A method for operating a radiographic imaging apparatus for capturing a plurality of x-ray images of an object comprising:

• providing a scintillation screen for receiving incident radiation and responding by emitting excited radiation at a first band of wavelengths;
• providing an array of photosensors, each photosensor extending between a first side and a second side, the first side for receiving first light at the first band of wavelengths from the scintillator, the second side for passing a portion of the first light that was not absorbed as second light responsive to impingement of the first light;
• providing a reflective layer for receiving the second light and for reflecting a portion of the second light as third light responsive to impingement of the second light;
• and
• providing a substrate over the second side for supporting the array of photosensitive elements, said each photosensor of the array of photosensors absorbing a prescribed amount of the first light and absorbing a prescribed amount of the third light received through the second side, wherein the reflectivity of the reflective layer is greater than 50%, wherein the absorption of the third light comprises at least 15% of total absorption of the plurality of photosensitive elements for light between 550 nm to 700 nm.
