View Patent ↗Certain embodiments of the present invention provide systems and methods for electromagnetic calibration of an instrument. Certain embodiments provide an electromagnetic instrument calibration system including electromagnetic receiver electronics for receiving electromagnetic field information from an electromagnetic transmitter. The system also includes a calibration mount configured to position the electromagnetic receiver electronics stationary with respect to the calibration mount for calibrating an instrument having an electromagnetic transmitter using the calibration mount and the electromagnetic receiver electronics. Certain embodiments provide a method for calibration of an instrument based on electromagnetic field information including providing a calibration mount accommodating a plurality of instruments in a known position and orientation and having electromagnetic calibration electronics positioned with respect to the calibration mount; receiving electromagnetic field information for an instrument with respect to a known position of the calibration mount and electromagnetic calibration electronics; and calibrating at least a portion of the instrument.
1. An electromagnetic instrument calibration system, said system comprising:
electromagnetic receiver electronics for receiving electromagnetic field information from an electromagnetic transmitter of a tracking assembly; and
a calibration mount affixed to said electromagnetic receiver electronics so that a position of said electromagnetic receiver electronics is stationary with respect to said calibration mount, said electromagnetic instrument calibration system configured to calibrate an instrument having said electromagnetic transmitter with respect to a medical navigation system, said electromagnetic calibration system configured to calibrate said instrument received at said calibration mount using said calibration mount and said electromagnetic receiver electronics.
2. The system of claim 1 , wherein said calibration mount comprises a dimple for positioning said instrument with respect to said calibration mount and said electromagnetic receiver electronics to calculate position and orientation of the instrument and calibrate a tip of said instrument.
3. The system of claim 1 , wherein said calibration mount comprises one or more channels for positioning said instrument with respect to said calibration mount and said electromagnetic receiver electronics to calculate position and orientation of the instrument and calibrate an angle of said instrument.
4. The system of claim 1 , further comprising a sleeve for protecting said electromagnetic receiver electronics.
5. The system of claim 1 , wherein said calibration mount comprises an autoclavable material.
6. The system of claim 1 , wherein said calibration mount further comprises a holder for positioning said electromagnetic receiver electronics stationary with respect to said calibration mount by affixing said electromagnetic receiver electronics to said calibration mount.
7. The system of claim 6 , wherein said holder comprises at least one of a clip and a snap.
8. The system of claim 1 , wherein said electromagnetic receiver electronics transmits said received electromagnetic field information to an external system for calibrating said instrument with respect to a reference coordinate system.
9. A method for calibration of an instrument, said method comprising:
receiving an instrument comprising an electromagnetic transmitter of a tracking assembly at a calibration mount affixed to electromagnetic receiver electronics so that the position of said electromagnetic receiver electronics is stationary with respect to said calibration mount;
receiving, at said electromagnetic receiver electronics, electromagnetic field information from said electromagnetic transmitter of said instrument; and
calibrating said instrument received at said calibration mount with respect to a medical navigation system using said calibration mount and said electromagnetic receiver electronics.
10. The method of claim 9 , wherein said receiving said instrument comprises using a dimple at said calibration mount for positioning said instrument with respect to said calibration mount and said electromagnetic receiver electronics to calculate position and orientation of the instrument and calibrate a tip of said instrument.
11. The method of claim 9 , wherein said receiving said instrument comprises using one or more channels for positioning said instrument with respect to said calibration mount and said electromagnetic receiver electronics to calculate position and orientation of the instrument and calibrate an angle of said instrument.
12. The method of claim 9 , comprising protecting said electromagnetic receiver electronics with a sleeve.
13. The method of claim 9 , wherein said calibration mount comprises an autoclavable material.
14. The method of claim 9 , comprising affixing said electromagnetic receiver electronics to said calibration mount using a holder for positioning said electromagnetic receiver electronics stationary with respect to said calibration mount.
15. The method of claim 14 , wherein said holder comprises at least one of a clip and a snap.
