Abstract:
1. A method of ensuring that an image of internal anatomical features obtained by an endoscope system having an endoscope console and an endoscope tip accurately portrays the anatomical features, wherein the endoscope system includes a biopsy channel extending the length of an endoscope tip from an access port at its proximal end to an opening at its distal end, the method comprising: positioning the endoscope tip so that the internal anatomical features are within a field of view of the endoscope tip; using the endoscope system to obtain an image of the internal anatomical features; introducing a calibrating device having at least one known optical property into the field of view of the endoscope tip, wherein introducing the calibration device comprises: using the endoscope system to obtain an image of the calibrating device; providing calibration device data corresponding to the at least one known optical property of the calibration device; using the image of the calibration device and the calibration device data to provide calibration data; and using the calibration data to program the endoscope system.
