System and method for multimodal image acquisition and image visualization

A system for multimodal image acquisition and image visualization, comprising:

• a surgical-microscopic system with an optical unit and an image sensor, which is designed for acquiring a time-resolved image signal of a selected field of view of a sample, wherein the image signal comprises a multiplicity of first tuples which each represent a surface element of the sample and at least one greyscale value;
• an optical coherence topography (OCT) system designed to acquire a time-resolved OCT signal of the selected field of view, wherein the OCT signal comprises a multiplicity of second tuples which each represent a volume element of the sample and a scattering intensity;
• a display means designed for the time-resolved display of image data with a multiplicity of pixels;
• and
• a control unit, which is configured
• to ascertain video image data corresponding to the acquired image signal and to present them on the display means, wherein the video image data are ascertained on the basis of the first tuples and of a resolution of the display means in a manner such that specific pixels display specific surface elements,
• to ascertain a time-resolved OCT image, corresponding at least to a portion of the presented video image data, on the basis of the acquired OCT signal and to present the time-resolved OCT image on the display means at the position of the portion, wherein the time-resolved OCT image is ascertained on the basis of the second tuples and of the resolution of the display means and/or of the video image data in a manner such that the volume elements corresponding to the specific surface elements are presented on the specific pixels, and wherein the video image data is overlaid with the time-resolved OCT image.
