Abstract
Official abstract text for this publication.
In a system and a method for examining an object containing a fluid liquid, the object is illuminated with measuring light and images are temporarily shortly subsequently recorded. The images are evaluated per pixel to determine perfusion data from a high frequency portion above 1 kHz and to determine further information about properties of the object from a low frequency portion below 100 Hz, such as a degree of oxygenation of hemoglobin, a concentration of hemoglobin or a concentration of ICG. This information determined by evaluation is displayed in a form of an image in superposition with a white light image of the object.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for examining an object containing a flowing liquid, the method comprising: illuminating the object with measuring light and recording at least one sequence of first images (I k (i,j); k=1, . . . , N) of the illuminated object, wherein an exposure time for each recording of an image of the at least one sequence of first images (I k (i,j); k=1, . . . , N) is smaller than 1 ms; evaluating, with an evaluation system, the at least one sequence of firs…
