Exposed film demonstrating distinct radiation fields on the skin when the C-arm was rotated between 12° LAO and 12° RAO (16 cm field of view (FOV) on Artis zee, Format group B). The top of the image representing the right side of the anthropomorphic phantom representing a medium patient, and therefore irradiation at the 12° LAO angle. The window/level was adjusted to clearly delineate the two fields (LAO, left anterior oblique; RAO, right anterior oblique).
