Abstract: Apparatus and methods are disclosed for selectively positioning a collimator body. The apparatus comprises support means adjustably supporting the collimator body; and adjustment means for selectively adjusting the collimator body, the adjustment means comprising an actuator component having a driver coil and a magnetic structure with a first gap formed therebetween; wherein an electrical current through the driver coil of the actuator component causes the collimator body to move perpendicular to a magnetic field created by the magnetic structure of the actuator component. The method comprises supporting the collimator; and adjusting the collimator body using an actuator component having a driver coil and a magnetic structure with a first gap formed therebetween; wherein an electrical current through the driver coil of the actuator component causes the collimator body to move perpendicular to a magnetic field created by the magnetic structure of the actuator component.
