Patent ID: 8822930

Claim:
A flat image detector comprising: a scintillator configured to convert X-ray radiation into light; a first active matrix arranged on a first side of the scintillator; and a second active matrix arranged on a second, opposite side of the scintillator, such that the scintillator is arranged between the first and second active matrices; wherein each of the first and second active matrices comprises a two-dimensional array of pixel-readout units of a substantially similar layout, each pixel-readout unit having a substantially equivalent size; wherein the flat image detector is arranged with an outer surface of the first active matrix acing a source of incident X-ray radiation; wherein the flat image detector is configured such that, upon receiving the incident X-ray radiation through the first active matrix and into the scintillator, both the first active matrix and the second active matrix arranged on opposite sides of the scintillator are configured to read out light generated in the scintillator, wherein the first active matrix is configured to generate a first two-dimensional image and the second active matrix is configured to generate a second two-dimensional image; and electronics configured to combine the first two-dimensional image generated by the first active matrix with the second two-dimensional image generated by the second active matrix by addition or averaging, further process the first and second two-dimensional images on an individual basis, or link the first and second two-dimensional images using a linear combination.
