A system for taking fluoroscopic images of large animals having a rotatable plate with a plurality of detectors disposed on the rotatable plate, wherein the detectors are arranged as spokes extending radially outwardly from a central rotational point on the rotatable plate with collimators disposed on the side edges of the spokes. A drive assembly rotates the plate about an axis extending through the central rotational point at a speed such that the duration of successive image frames corresponds to the time taken for each spoke of detectors to move to the position of an adjacent spoke of detectors.
