The instrument (10) has a distal part (12), proximal part (14) selectively couplable to the distal part, and multiple trackable markers arranged on the instrument. A passive reflection marker (13) is arranged on the distal part at a mid point from a longitudinal axis (18) and a single tracking marker (15) is arranged on the proximal part. A configuration or arrangement of the passive reflection marker on the distal part is uniquely assigned to a functional portion relative to a marker geometry of the proximal part. |
