Abstract
A radiation imaging method and system for use in various imaging techniques includes a source of radiation at first and second wavelengths. A first radiation target array receives the radiation from the first wavelength at first spacial locations to produce an array of output signals at locations within the first radiation target array related to the magnitude of the radiation at each of the first spacial locations. A second radiation target array receives the radiation at the second wavelength at second spacial locations to produce an array of output signals at locations within the second radiation target array related to the magnitude of the radiation at each of the second spacial locations. The first and second outputs are combined to produce combined image signals that has increased contrast from that which would be produced by either the first or the second output alone. In a preferred embodiment, the first and second radiation target arrays comprise amorphous silicon arrays in which sensor data from the first and second radiation targets is synchronously clocked from the array.
