Abstract:
1. A method for processing image data comprising image information about a body region of a patient, the method being executed by an electronic data processing device and comprising the following steps: a) providing the image data; b) assigning, to elements of the image information, a predetermined probability for the image information contained in the respective element representing a predetermined tissue class, wherein the predetermined probability is provided independently of information about at least part of a body which is different from the body of the patient, wherein the predetermined probability represents an expected value for the element-specific probability; c) determining, on the basis of the predetermined probability and for a subset of the image information comprising a plurality of the elements, an element-specific probability for individual elements of the subset representing an element-specific tissue class, wherein a likelihood for an individual element representing the element-specific tissue class is determined, wherein the likelihood is maximized by applying an expectation-maximisation algorithm, and wherein the likelihood is represented by a log-likelihood.
