Abstract: The invention relates to a medical data processing method of segmenting image features in medical images generated with different imaging modalities, wherein the image features represent a corresponding anatomical structure in each of the medical images, the method being constituted to be executed by a computer and comprising the following steps: a) acquiring (SI) first modality medical image data describing a first modality medical image containing a first modality image representation of the anatomical structure; b) acquiring (SI) second modality medical image data describing a second modality medical image containing a second modality image representation of the anatomical structure; c) determining, based on the first modality medical image data and the second modality medical image data, modality transformation data describing a mapping transformation between the image information in the first modality image data and the image information in the second modality image data; d) acquiring colour value data describing a colour value of the image elements in the first modality medical image and in the second modality medical image; e) determining (S2-S7), based on the first modality medical image data, first modality segmentation data describing the result of segmenting the first modality image representation from the first modality medical image data; f) determining (S8-S10), based on the first modality segmentation data and the modality transformation data and the colour value data, second modality segmentation data describing a result of segmenting the second modality image representation from the second modality medical image data.
