摘要：
A diagnostic scanning apparatus includes a hollow rotor sized to receive a patient. First and second flanges are connected to and extend radially outward from the rotor in a spaced-apart relationship, each of the first and second flanges including, at least in part, a magnetically-permeable material. A radiation source is affixed to the first flange and/or the rotor. A first axial actuator generates a variable magnetic field, is fixedly disposed adjacent to the first flange and can magnetically pull the first flange in a first axial direction of the rotor. A second axial actuator generates a variable magnetic field, is fixedly disposed adjacent to the second flange and can magnetically pull the second flange in a second axial direction of the rotor that is opposite of the first axial direction. The first and second axial actuators are both at least substantially disposed between the first and second flanges.
