title: Carbon-fiber materials in radiology.
abstract: While cassettes, table tops, and film changers made of carbon fiber have been recommended by many authors, there is controversy as to whether the advantages of the new materials outweigh the marked increase in cost. Carbon-fiber materials transmit more lower-energy radiations; thus a lower mAs can be used, which in turn permits a reduction of 15-30% in exposure time. However, x-ray transmission under actual clinical conditions has not been as good as originally hoped.
