ABSTRACT:
A method and apparatus for calibrating an endoscope includes an endoscope system configured to acquire a first calibration image at a first calibration focal length and determine a radius of a first calibration image boundary corresponding to the first calibration focal length for the first calibration image, wherein the radius of the first calibration image boundary corresponds to a first calibration magnification of the endoscope. A clinical image is acquired at a clinical focal length, wherein the first calibration focal length is different than the clinical focal length and a radius of a clinical image boundary corresponding to the clinical focal length for the clinical image is determined, wherein the radius of the clinical image boundary corresponds to a clinical magnification of the endoscope. The radius of the first calibration image boundary is compared to the radius of the clinical image boundary to determine a change in magnification of the endoscope.
