Abstract:
The present invention relates to an apparatus for multi material decomposition of an object. It is described to provide ( 310 ) at least one image of an object. The at least one image is derived from at least one spectral X-ray image of the object, and the at least one image comprises a Photoelectric total attenuation coefficient image and a Compton scattering total attenuation coefficient image. A plurality of Photoelectric attenuation coefficients are provided ( 320 ) for a plurality of materials, each Photoelectric attenuation coefficient being associated with a corresponding material. A plurality of Compton scattering attenuation coefficients are provided ( 330 ) for the plurality of materials, each Compton scattering attenuation coefficient being associated with a corresponding material. A total volume constraint is set ( 340 ) at an image location in the at least one image as a function of the sum of individual volumes of the plurality of materials at the image location. Volume fractions of the plurality of materials are determined ( 350 ) at the image location according to an overall function comprising: a Photoelectric total attenuation coefficient at the image location taken from the Photoelectric total attenuation coefficient image; a Compton scattering total attenuation coefficient at the image location taken from the Compton scattering total attenuation coefficient image; the plurality of Photoelectric attenuation coefficients for the plurality of materials; the plurality of Compton scattering attenuation coefficients for the plurality of materials; and the total volume constraint. Data representative of the volume fractions of the plurality of materials is output ( 360 ).
