1. An apparatus for displaying an angulation on an x-ray image, the apparatus comprising: an x-ray device configured to produce x-ray images of an object between the x-ray device and a cassette; an enclosure attached to a surface of the cassette, the enclosure having a first passageway within the enclosure through which a first movable object travels in relation to an angulation at which the cassette is currently disposed, and the enclosure having a second passageway within the enclosure through which a second movable object travels in relation to the angulation at which the cassette is currently disposed; a first plurality of markers positioned adjacent to the first passageway through which the first movable object travels, wherein a position of the first movable object in relation to the first plurality of markers represents a first angle at which the object is positioned at a time when the x-ray image is taken; and a second plurality of markers positioned adjacent to the second passageway through which the second movable object travels, wherein a position of the second movable object in relation to the second plurality of markers represents a second angle at which the object is positioned at a time when the x-ray image is taken; wherein the first and second angles are defined in respective perpendicular planes; and wherein the first and second movable objects and the first and second pluralities of markers are visible on the x-ray image produced by the x-ray device.
