Abstract
Apparatus and methods for collimation of x-ray beams. According to various embodiments, an x-ray apparatus may comprise a first rotatable disk comprising a first plurality of angled slots and a first shutter comprising a first plurality of protruding members. At least one of the first plurality of protruding members may be positioned within a first angled slot of the first plurality of angled slots, and at least one of the first plurality of protruding members may be positioned within a second angled slot of the first plurality of angled slots. The first shutter may at least partially define an x-ray collimation aperture, and the apparatus may be configured such that rotation of the first rotatable disk results in movement of the first shutter to alter a size of the x-ray collimation aperture.
