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 3):
The method of  claim 1 , wherein said at least one other basis function that models the NLPV effect is constructed by:\n selecting (S 11 ) a set of at least one ordinary basis function, such that the energy dependent linear attenuation coefficients of homogeneous materials in the image volume can be described by a linear combination of the basis functions in the set; determining (S 12 ) the fraction of transmitted photons as a function of energy for a detector element situated behind an inhomogeneous region of materials, as seen from the source, taking into account the spatially extended nature of either the detector, the source or both; and determining (S 13 ) at least one NLPV basis function as the linear attenuation coefficient of a fictious material which, if one unit of distance of a homogeneous slab of this material were traversed by an x-ray beam, would give the same transmitted photon fraction as a function of energy as said calculated fraction which is transmitted through an inhomogeneous region.
