Claim 0:
1. A method for generating a resultant image dataset of a patient, the method comprising:
capturing a first image dataset of the patient based on a first X-ray quantum energy distribution and at least one second image dataset of the patient based on at least one second X-ray quantum energy distribution;
first establishing a first spatial distribution of at least one first material in the patient based on the first image dataset and the at least one second image dataset via a basis material decomposition;
second establishing background image datasets based on the first image dataset and the second image dataset, the established background image datasets including a background image dataset associated with the first X-ray quantum energy distribution and a background image dataset associated with the second X-ray quantum energy distribution;
adapting values of the established background image datasets in regions in which the established first spatial distribution indicates a presence of the at least one first material, the adapting including applying a tissue image value associated with a respective X-ray quantum energy distribution to the values of the respective background image dataset corresponding to the X-ray quantum energy distribution, the adapting including,
applying the adapted values to at least one of the first image dataset or the second image dataset;

after the applying, third establishing a second spatial distribution of at least one second material in the patient based on the first image dataset and the second image dataset using a material decomposition and further based on the applying; and
generating a resultant image dataset based on at least the second spatial distribution of the second material.
