PROBLEM TO BE SOLVED: To provide an improved system and method for targeting landmarks on medical implants so as to be accurate and reliable.SOLUTION: A system for targeting landmarks on devices such as surgical implants is disclosed. The system can include a field generator for generating one or more magnetic fields, an orthopaedic implant located within the magnetic fields, the implant having at least one landmark, a removable probe with a first magnetic sensor, a landmark identifier and a processor. The landmark identifier can include a second sensor, or alternatively, the field generator. The processor can utilize sensor data and, if desirable, field generator and other information in order to generate and display the position and orientation of the sensor(s) in preferably six degrees of freedom and thereby to generate and display the position and orientation of the landmark(s). |
