Patent Images
1. A method of monitoring the position of a medical instrument in three-dimensional space and in real-time during a medical procedure being performed on a patient, the method comprising:
- acquiring imaging of a predetermined portion of the anatomy of a patient;
providing a medical instrument, the medical instrument comprising one or more electromagnetically detectable receiver coils, the position of which can be determined in three-dimensional space and in real-time;
placing the at least a portion of the medical instrument within the predetermined portion of the anatomy of the patient;
identifying the position, in three-dimensional space and in real-time, of the at least a portion of the medical instrument placed within the predetermined portion of the anatomy of the patient;
displaying the previously acquired imaging of the predetermined portion of the anatomy of the patient on a display screen; and
indicating the position of the at least a portion of the medical instrument on the display screen.

16. A medical navigation system that can monitor the position of a medical instrument in three-dimensional space and in real-time during a medical procedure being performed on a patient, the medical navigation system comprising:
-
at least one medical instrument comprising a body portion comprising an electromagnetically detectable receiver coil integrated with the body portion and configured so the position of at least a portion of the electromagnetically detectable receiver coil can be determined in three-dimensional space and in real-time; an electromagnetic transmitter configured to transmit a signal to the at least a portion of the electromagnetically detectable receiver coil; a source of previously acquired imaging of a predetermined portion of the anatomy of the patient; and a display screen configured to display the previously acquired imaging of the predetermined portion of the anatomy of the patient; a user interface configured to receive information from the electromagnetic transmitter and display the previously acquired imaging of the predetermined portion of the anatomy of the patient together with a real-time graphical and positional representation of at least a portion of the medical instrument. - View Dependent Claims (17, 18, 19, 20)
