Claim:
1. A method to estimate multi-energy data, comprising data indicative of a first radiation energy spectrum and data indicative of a second radiation energy spectrum, in a radiation imaging modality comprising a detector array comprised of a plurality of detector cells, a first set of the detector cells configured to detect the first radiation energy spectrum and a second set of the detector cells configured to detect the second radiation energy spectrum, the method comprising: generating a partial first data set using data yielded from the first set of detector cells, the partial first data set excluding data yielded from the second set of detector cells; generating a partial second data set using data yielded from the second set of detector cells, the partial second data set excluding data yielded from the first set of detector cells; estimating the data excluded from the partial first data set based upon the partial first data set to generate a complete first data set indicative of the first radiation energy spectrum; and estimating the data excluded from the partial second data set based upon the partial second data set and the complete first data set to generate a complete second data set indicative of the second radiation energy spectrum.
