Abstract

The invention relates to a computer-implemented method for identifying a region (21) of a tumour (23) in a tissue-field image (27), which image shows a tissue region (25) having a tumour (23) and has been obtained by means of light reflected or emitted by the tissue region (25). In the method, the region (21) of the tumour (23) in the tissue-field image (27) is identified on the basis of a characteristic value for the intensity of at least one component of the light reflected or emitted by the tissue region (25). The characteristic value is determined using the intensity of the at least one component in an image detail of the tissue-field image (27), which image detail corresponds to a tissue portion (36, 36′) of the tissue region (25) at which at least one piece of histological information was obtained.

Claims22

Dependent claims

A computer-implemented method comprising:

marking a boundary of a tumor in a tissue field image which shows a tissue region with a tumor and which has been obtained by light reflected or emitted by the tissue region, the boundary of the tumor being marked in the tissue field image based on a characteristic for an intensity or a temporal intensity profile of at least one constituent part of the light reflected or emitted by the tissue region,
wherein the characteristic is determined based on the intensity or the temporal intensity profile of the at least one constituent part in an image portion, the image portion being a sub-portion of the tissue field image, the image portion corresponding to a tissue segment of the tissue region from which at least one histological information item is determined based on at least one histology image recorded at the image portion and applied to the tissue field image entirely.

Dependencies are inferred from the claim text.
