Abstract:

A system and a method for examining an object containing a fluid liquid are provided, wherein 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 haemoglobin, a concentration of haemoglobin 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.
