Abstract: A mobile imaging system or mini C-arm with a variable aperture assembly is disclosed. The mini C-arm includes a detector and a moveable source. The aperture assembly being operatively coupled to the moveable source. The aperture assembly including a plurality of independently controllable blades such as, for example, first, second, third, and fourth blades, to define a variable aperture through which an X-ray beam is passed from the source to the detector. In one embodiment, each of the plurality of blades is independently controlled. In one embodiment, the aperture assembly includes a PCB sensor aligned with the plurality of blades for detecting a position of each of the plurality of the blades.
