1. A method for determining position and orientation of an endoscopy capsule guided through an examination object using a navigating magnetic field, the method comprising:
- using an X-ray machine to record radiation images in which the endoscopy capsule is shown; and
determining the position and orientation of the endoscopy capsule with the aid of position-dependent and orientation-dependent image of the endoscopy capsule in the radiation images.

Abstract
A method is disclosed for determining the position and orientation of an endoscopy capsule guided through an examination object by using a navigating magnetic field generated by way of a navigation device. In the method, an X-ray machine is used to record radiation images in which the endoscopy capsule is shown. Further, the position and orientation of the endoscopy capsule are determined with the aid of the position-dependent and orientation-dependent image of the endoscopy capsule in the radiation images.
