Abstract:
1. An aperture actuator assembly for use in actuating a variable aperture assembly disposed over a window of a radiation detector housing in an imaging device, the variable aperture assembly including an aperture drive mechanism having a body and an actuator coupling member extending at an angle away from a plane of the body and adapted to be moved in a first lateral direction so that the variable aperture assembly defines a first aperture over the window and in a second lateral direction so that the variable aperture assembly defines a second aperture over the window, the aperture actuator assembly comprising: an actuator adapted to be disposed adjacent to the radiation detector housing below the actuator coupling member; and an actuator arm coupled to the actuator and the actuator coupling member so that the actuator controls the lateral movement of the actuator coupling member.
