METHOD FOR CALIBRATING A DEVICE FOR IMAGING THE INTERIOR OF TURBID MEDIA AND METHOD FOR CORRECTING MEASURED INTENSITIES IN SUCH A DEVICE

摘要

A method for calibrating a device for imaging the interior of turbid media is provided. The device for imaging the interior of turbid media uses a fluorescent contrast agent emitting fluorescence light and comprises a receptacle (2) for receiving a turbid medium during examination; at least one light source (6) optically connected to the receptacle (2) for irradiating the interior of the receptacle with light of a predetermined wavelength (?^); at least one detector (7) optically connected to the receptacle (2) for detecting light emanating from the interior of the receptacle; and at least one filter (11) introducible in the detection light path from the receptacle (2) to the at least one detector (7). The method for calibrating comprises the steps: - performing a first reference measurement with the receptacle (2) filled with an optically matching medium (4); - performing a second reference measurement with the receptacle (2) filled with a mixture (10) of the optically matching medium and a fluorescent contrast agent; - calibrating the device based on the results of the first reference measurement and the second reference measurement.
