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 1):
An image processing method for medical imaging including processing a radiographic x-ray image acquired with at least two energy levels, said method comprising the steps of:\n providing (S 1 ) energy-resolved image data representative of said radiographic x-ray image with at least two energy levels, from a detector or from an intermediate storage, where it is assumed that x-rays have traversed a volume of materials with different linear attenuation coefficients; generating at least one image representation for medical imaging by decomposing (S 2 ) said 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, 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.
