Abstract: The method involves determining the spatial position of the instrument (4) and a reference specimen (6) whilst simultaneously determining a periodic movement signal related to movement of a body organ (3), selecting a 3D image data set from a database of preoperative motion phase image data sets and determining the instrument position relative to the organ by converting its spatial position using the known position of the reference specimen. Independent claims are also included for the following: an arrangement for determining the position of a medical instrument inserted into the body of a patient.
