Abstract
The invention provides a method for data reduction in the context of spectral CT imaging. The method comprises reducing the number of spectral channels of the acquired CT data by a reduced set of synthetic energy channels, each from a weighted combination of the original measured energy channel. The weights are selected in an optimization process in which an error metric associated with an output of a material decomposition procedure to be applied to the CT data is estimated, and the weights adjusted to minimize a value of the error metric. The error might for example be a noise estimate, and/or a bias estimate.
