Abstract

A method is disclosed for displaying a tissue containing a fluorescent dye at least in sections. In order to reduce interference signals, it is proposed to record a first fluorescent image during an illumination phase, and a second fluorescent image during a dark phase, and to correct the first fluorescent image by subtracting the second fluorescent image and to process it subsequently to form an overall image.
