The invention relates to a rotor, in particular for a current-excited synchronous machine, comprising a rotor main body which has a plurality of rotor teeth, the rotor teeth being wound with a conductor material in order to form a winding, the conductor material having conductor ends which, in order to produce an electrical connection, are pressed axially against a stop via a contact element, and the contact element or the stop being designed to electrically connect, in the circumferential direction, at least two conductor ends.

Rotor and method for producing a rotor

A rotor for an electric machine includes a rotor main body which has at least two poles between which in the circumferential direction of the rotor is disposed at least one pole gap, and a rotor shaft which is coupled in a rotationally fixed manner to the rotor main body. The rotor has a support device which has a covering body that is configured for covering at least regions of an end side of the rotor main body. The support device has an annular body, which is different from the covering body, and in the direction of radial extent of the rotor is braced in relation to the rotor main body, on the one hand, and in the direction of radial extent of the rotor is braced in relation to the covering body, on the other hand.

The invention relates to an image output method for medical navigation in which the positional relationship of an instrument with respect to a part of a patient's body is ascertained, and in which the instrument and the part of the patient's body are displayed in the correct positional relationship on an image output, wherein the display of the part of the patient's body is based on the one hand on virtual image data captured by means of a medical imaging method and on the other hand on actual images captured during navigation, wherein the virtual image data is displayed on the image output primarily and as the basis of the image, and the actual images are superimposed on it merely as an addition and secondarily. It also relates to an image generating and image output device for medical navigation.

An improved marker system, components and method for use with a medical navigation system, wherein the marker system includes interchangeable tracking marker holders and fastener bases for attaching the marker holders to instruments or body parts that are to be tracked during a medical procedure. A reference star (the marker holder and tracking marker(s)) and fastener base are removably attached to one another. This enables different reference stars to be interchangeably attached to a given fastener base, or vice versa, thereby to provide the best combination of reference star and fastener base for a given application. This preferably is accomplished by a standard interface between the fastener base and the holder for the tracking markers, e.g., reflective markers. In addition, surgical instruments may have integrally formed therein the standard interface, thereby eliminating the need for a fastener base.
