Patent ID: 7696481

Claim:
An imaging system comprising: an x-ray source; a first detector array including a first array of first diodes disposed on a first scintillation layer of scintillator material for sensing the x-ray source, the first detector array defining a curvilinear image plane and associated x-ray capture fields subtending predefined solid angles of flux from the x-ray source, two or more of the first diodes having a combined geometric area defining a capture field corresponding to a predefined solid angle of flux, each capture field being an effective x-ray sensing area at a position along the curvilinear image plane; and a second detector array including a second array of second diodes disposed on a second scintillation layer of the scintillator material, wherein each second diode subtends a solid angle substantially equal to the predefined solid angle of flux, the second scintillation layer positioned to absorb a portion of the x-rays transmitted from the x-ray source and passing through the first scintillation layer.
