Patent application numberDescriptionPublished
20100041999Process for quantitative display of blood flow - A method for the quantitative representation of the blood flow in a tissue or vascular region based on the signal of a contrast agent injected into the blood. In the process, several individual images of the signal emitted by the tissue or vascular region are recorded at successive points in time and are stored. For image areas of stored individual images the respective point in time is determined at which the signal has exceeded a certain threshold value and this point in time is represented for each of the image areas.02-18-2010
20100044583FILTER SET FOR OBSERVING FLUORESCENCE RADIATION IN BIOLOGICAL TISSUE - A filter set for observing fluorescent radiation in biological tissue includes at least one illumination filter and at least one observation filter. The at least one illumination filter is arrangeable in an illumination system of an optical system. The at least one least one observation filter is arrangeable in an imaging system of the optical system.02-25-2010
20100069759Method for the quantitative display of blood flow - A method for the quantitative representation of the blood flow in a tissue or vascular region is based on the signal of a contrast agent injected into the blood. Several individual images of the signal emitted by the tissue or vascular region are recorded and stored at successive points in time. For image areas of the individual images, the respective intensities of different points in time are compared and the maximum intensities of the signals are determined for these image areas. The maximum intensities are represented for these image areas.03-18-2010
20100110538MICROSCOPE SYSTEM - Disclosed is a microscope system (05-06-2010
20100182418SURGICAL MICROSCOPE FOR OBSERVING AN INFRARED FLUORESCENCE AND CORRESPONDING METHOD - A surgical microscope for observing an infrared fluorescence includes a camera system 07-22-2010
20100302629Surgical microscope having an illuminating system and control unit therefor - A surgical microscope (12-02-2010
20110028850Process for quantitative display of blood flow - A method for the quantitative representation of the blood flow in a tissue or vascular region is based on the signal of a contrast agent injected into the blood. In the method, several individual images of the signal emitted by the tissue or vascular region are recorded at successive points in time and are stored. Based on the respective signal, a quantity characteristic for the blood flow and a quantity characteristic for the position of the blood vessels are determined for image areas of individual images. These quantities are represented superimposed for the respective image areas such that both the blood flow quantity and the position of the fine blood vessels become clearly visible in the representation and can be differentiated from the tissue.02-03-2011
20110164315Surgical Microscope having an Illuminating Arrangement - A surgical microscope (07-07-2011
