Older systems may contain a spot film device that allows placement of a radiographic cassette in front of the fluoroscopic image receptor, facilitating the acquisition of radiographs using the fluoroscopic X-ray source. In addition to beam shaping filters, many fluoroscopy systems have wedge filters that are partially transparent to the X-ray beam.
