The method involves determining whether a position of form representatives fulfills a positioning criteria, where the position of the form representatives is related to a relative position of two contact surfaces of a tool (100). Tool marker position data and body structure marker position data are determined when the fulfillment of the positioning criteria is determined. Tool data are provided, where the tool data describes the relative position of two contact surfaces (110, 114) of the tool relative to a tool marker device (120). Independent claims are also included for the following: (1) a program comprising instructions stored on a computer to perform a data processing method for determining adjustable length of a tool (2) a navigation system comprising a computer with a program to perform a data processing method for determining adjustable length of a tool (3) a system comprising a navigation system. |
