Abstract
An endoscopic imaging system for viewing an object within a patient's body cavity includes: an endoscope for viewing an image of the object, the endoscope comprising a distal end, an instrument channel extending therethrough, and a lens at the distal end adjacent the instrument channel; and an elongate probe configured to be inserted through the instrument channel and contact the object, the probe comprising a plurality of unevenly spaced graduations along its length, each graduation indicating a size factor used to scale the image produced by the endoscope. The invention also relates to a method of determining the size of an object in a patient's body cavity including the steps of: generating an image of the object using an instrument; extending a probe having a series of unevenly spaced graduations from the instrument to the object; identifying the graduation on the probe visible in the image nearest to the instrument; and scaling the image viewed by the endoscope by a size factor corresponding to the identified graduation.
