A system (10) and method for targeting a geometric feature (12) in a medical implant (14) located in a patient (16), such as a transverse bore (12) in an intramedullary nail (14) implanted in a femur (18) of a patient (16). The system (10) includes one or more emitters (20), one or more receptors (22), and a processor (24). The emitter(s) emits at least one of an acoustic field, a magnetic field, an electric field, or an electromagnetic field that will be altered by the geometric feature (12), and the receptor(s) (22) detects the altered field and generates a signal (26) responsive to the altered field. The processor receives the signal and generates a representation of the altered field.
