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 11):
A system ( 120 ) for medical imaging based on processing a radiographic x-ray image acquired with at least two energy levels, wherein said system comprises processing circuitry and memory, the memory comprising instructions executable by the processing circuitry, whereby the processing circuitry is operative to:\n obtain energy-resolved image data representative of said radiographic x-ray image with at least two energy levels, where it is assumed that x-rays have traversed a volume of materials with different linear attenuation coefficients; generate at least one image representation for medical imaging by performing basis decomposition of said 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, where at least one basis function, also referred to as an ordinary basis function, models a physical material and at least one other basis function, also referred to as an NLPV basis function, models the Non-Linear Partial Volume, NLPV, effect, which represents the effect where an exponential form of x-ray attenuation makes a measured x-ray transmission a non-linear function of the attenuation coefficients of the materials.
