A method for controlling movement of an imaging device in vivo, the method comprising the steps of providing an imaging device having a longitudinal axis and a magnetic component, said device to be inserted into a patient's body; providing a rotating magnetic field outside the patient's body; and advancing the rotating magnetic filed along the patient's body in a desired direction.

System and method for magnetically maneuvering an in vivo device

A magnet arrangement for generating an NMR-compatible homogeneous permanent magnetic field is described. The invention has two permanent magnets, referred to hereafter as main magnets, which each have a magnet pole surface area. The magnet pole surface areas are situated parallel and at a distance to one another, so that the main magnets define an interspace on both sides through their magnet surface areas. The magnet pole surfaces of the main magnets each have a magnetic polarization opposite to one another. At least two annular permanent magnets are used, which are referred to hereafter as ring magnets, are situated coaxially to one another and jointly radially bound a ring inner chamber. The ring magnets are situated relative to the two main magnets in so that the ring inner chamber at least regionally encloses the interspace, and the magnetic fields of the main and ring magnets are constructively superimposed.
