A surgical designator (20) includes a fixation member (24), adapted to be inserted into hard tissue (27) of a patient at a single point on the tissue. A plurality of emitters (26, 28, 30), including at least first and second emitters, are rigidly attached to the fixation member at predetermined, mutually-spaced locations and are operative to emit energy such that when the energy emitted by the emitters is received by a receiver (25) remote from the designator, the energy received from the first emitter is distinguishable from the energy emitted from the second emitter. |
