Patent ID: 8092400

Claim:
A method for calculating the position of body parts, taking into account anatomical symmetry, wherein a first and second first-side body part are provided on the first side of an anatomical body and connected by a first-side movable joint, said first-side moveable joint enabling movement of the first first-side body part relative to the second first-side body part, wherein a first and second second-side body part are provided on the second side of the anatomical body and connected by a second-side movable joint, said second-side movable joint enabling movement of the first second-side body part relative to the second second-side body part, said method comprising the steps of: providing second-side relative position data which describes the relative position of the first second-side body part relative to the second second-side body part for each of a first and a second second-side relative placement due to movement of at least one of the first or second second-side body part about the second-side movable joint; providing first-side relative position data which describes the relative position of the first first-side body part relative to the second first-side body part in a first first-side relative placement; and calculating, using a processor, the position of the first first-side body part relative to the second first-side body part in a second first-side relative placement, on the basis of the first-side relative position data and the second-side relative position data, wherein it is taken into account that the second second-side relative placement is symmetrical with respect to the second first-side relative placement.
