Diagnostic scanning device

A diagnostic scanning device includes a hollow rotor in a form suitable for recording a patient's size. The first and the second flange are connected to the rotor and extend in a spaced apart relationship from the rotor radially outward, wherein both the first and the second flange at least partially of magnetically permeable material. A radiation source is mounted on the first flange and / or the rotor. A first axial actuator produces a variable magnetic field is fixedly disposed adjacent to the first flange and the first flange can pull magnetically in a first axial direction of the rotor. A second axial actuator produces a variable magnetic field is fixedly disposed adjacent to the second flange and the second flange can pull magnetically in a second axial direction of the rotor opposite to the first axial direction. The first and second axial actuators are both disposed at least substantially between the first and the second flange.
