摘要：
Methods, systems, and techniques are provided to a position determination device for determining a position of an instrument within a tubular structure. The position determination device comprises a first curvature values providing unit for providing first curvature values being indicative of first curvatures of the tubular structure at several first locations along the tubular structure and a second curvature values providing unit for providing second curvature values being indicative of second curvatures of the instrument at several second locations along the instrument. A position determination unit determines the position of the instrument within the tubular structure based on the first and second curvature values.
