摘要:
The present invention relates to an apparatus for determining a position of a first object (14) within a second object (13), wherein the first object (14) contacts the second object (13) at a contact region. The apparatus (1) comprises a provision unit (2) for providing a three-dimensional model (20) of the second object (13). A projection unit (5, 6, 7, 21) generates a two-dimensional projection image (26) of the first object (14) and of the second object (13), and a registration unit (8) registers the three-dimensional model (20) with the two-dimensional projection image (26). A determination unit (9) determines the position of the contact region from the position of the first object (14) on the two-dimensional projection image (26) and the registered three-dimensional model (20) of the second object (13), wherein the position of the contact region is the position of the first object (14) within the second object (13).
