MEDICAL IMAGE ANALYSIS FOR IDENTIFYING BIOMARKER-POSITIVE TUMOR CELLS

摘要

The invention relates to a medical image analysis method for identifying biomarker- positive tumor cells, the method comprising: - reading a first digital image (223) and a second digital image (222) into memory, the first and second digital image depicting the same area of a first slide; • the first slide comprising multiple tumor cells having being stained with a first stain and with a second stain; • the first stain selectively staining nuclei and the second stain selectively staining a particular biomarker, the presence and/or amount of the biomarker in a tumor cell being indicative of a tumor cell belonging to a particular cancer-subtype; - identifying a plurality of nuclei and positional information of said nuclei by analyzing the light intensities in the first digital image; - identifying cell membranes which comprise the biomarker by analyzing the light intensities in the second digital image and by analyzing the positional information of the identified nuclei; - identifying biomarker-positive tumor cells in said area, wherein a biomarker- positive tumor cell is a combination of one identified nucleus and one identified cell membrane that surrounds the identified nucleus.
