First Claim
Patent Images
1. A calibration tool for use in calibrating an image guided surgery system to an elongate medical device that has a substantially fixed shape and a distal end, said calibration tool comprising:
- a substantially rigid body having a receiving groove, a first calibration tip and a second calibration tip;
the medical device being insertable into the receiving groove with the distal end of the medical device in a known position within one of said first and second calibration tips;
said first and second calibration tips being alternately placeable in a known location relative to an electromagnetic transmitter.

3. A method for calibrating an image guided surgery system for use with an elongate medical device that has a substantially fixed shape and a distal end, said method comprising the steps of:
-
(A) providing a calibration tool comprising a substantially rigid body having a receiving groove, a first calibration tip and a second calibration tip formed therein; (B) inserting the medical device into the receiving groove with the distal end of the medical device positioned in a known position within one of said first and second calibration tips; (C) positioning the first calibration tip in a known position relative to an electromagnetic transmitter while obtaining at least one reading using the image guided surgery system; (D) positioning the second calibration tip in a known position in relation to the electromagnetic transmitter while obtaining at least one additional reading using the image guided surgery system; and (E) calibrating the image guided surgery system to the substantially fixed shape of the medical device on the basis of the readings obtained in Steps C and D. - View Dependent Claims (4, 5, 6, 7)
