Abstract:
There is provided a method for processing a radiographic image acquired with at least two energy levels. A first step (S 1 ) involves providing energy-resolved image data representative of the radiographic image with at least two energy levels, e.g. from a detector or from an intermediate storage. A second step (S 2 ) involves decomposing the provided image data into at least one basis image representation, based on a model where a combination of at least two basis functions is used to express a representation of at least one linear attenuation coefficient, and where at least one basis function models a physical material and at least one other basis function models the Non-Linear Partial Volume, NLPV, effect.

Claim (Index 7):
The method of  claim 1 , where the output basis image representation(s) include at least one sinogram of ordinary basis coefficient line integrals and at least one sinogram of NLPV basis coefficient line integrals, and where subsequently a set of ordinary tomographic basis images corresponding to ordinary basis functions is computed by minimizing a penalized data discrepancy between said at least one sinogram of ordinary basis coefficient line integrals and said at least one sinogram of NLPV basis coefficient line integrals, on one side, and at least one sinogram of simulated ordinary basis coefficient line integrals obtained from a forward projection of said tomographic basis images, on the other side, and where said forward projection is calculated with at least two line integrals from the source to each detector element, yielding a spatially variant basis coefficient line integral for each detector element, and where a mapping is used to translate a representation of said spatially variant basis coefficient line integrals into said at least one sinogram of simulated ordinary basis coefficient line integrals and said at least one sinogram of NLPV basis coefficient line integrals.
