摘要：
A system (1010, 1110) for identifying a landmark is disclosed.The system includes a field generator (1016, 1116) for generating amagnetic field, an orthopaedic implant (1030, 1130) located within themagnetic field, the implant having at least one landmark (1028,1128), aremovable probe (1029, 1129) with a first magnetic sensor (1026,1126), alandmark identifier (1016, 1116) with a second magnetic sensor (1020,1120) and a processor (1012, 1112) for comparing sensor data from thefirst and second sensor and using the set distance to calculate the positionof the landmark identifier relative to the at least one landmark. The systemallows for blind targeting of one or more landmarks.
