Abstract: A medical device with metal parts to be introduced into animal or human bodies is rendered visible during RMN imaging by covering the exterior surface of the metal parts with a layer comprising Nickel monoxide. When placed within the electromagnetic field generated by a NMR apparatus, the layer reduces disturbances induced in this field in the vicinity of the metal part. This improvement is chiefly related to endoprostheses for subjects or patients who will be submitted to NMR imaging. In particular, the invention is aimed at luminal endoprostheses comprising a metal frame, as stents.

Abstract: A controller is provided for maneuvering an interrogation plane relative to a reference surface. The interrogation plane intersects the reference surface and is associated with a pole about which the interrogation plane is rotatable. The pole has an adjustable angle of inclination relative to the reference surface. The controller has a base, a handle, and an arm extending from a connection with the base to a connection with the handle. The arm has hingable joints which hinge to allow the handle to be translated relative to the base in arbitrary directions across a user surface. The controller further has position sensors which measure the translation of the handle relative to the base on the user surface. The translation provides a corresponding translation of the interrogation plane relative to the reference surface. The handle is rotatable about a rotation axis and is tillable about a tilt axis to allow the handle to be angularly moved relative to the user surface. The controller further has angle sensors which respectively detect the rotation about the rotation axis and the tilt about the tilt axis. The rotation about the rotation axis and the tilting about the tilt axis provide angular movement of the interrogation plane relative to the reference surface corresponding to the angular movement of the handle relative to the user surface.
