The X-ray transmission of a number of radiographic components, some of conventional construction and some incorporating carbon fibre material, has been measured under clinically realistic conditions. At 80 kVp the use of carbon fibre materials enables the patient dose to be reduced by 30-50% depending on the existing equipment, type of examination and technique used. Typically the dose can be reduced by 3-15% by changing the table top, 6-12% by changing the front of the film cassette and 20-30% by using a grid with carbon fibre covers and fibre interspace. The higher cost of carbon fibre components can normally be justified by such dose savings. An indication of the absorption of all such components should be provided by manufacturers.
在临床实际条件下，对一些传统结构的以及一些采用碳纤维材料的多种射线照相组件的X射线透射率进行了测量。在80千伏峰值电压下，根据现有设备、检查类型和使用的技术，使用碳纤维材料可使患者剂量降低30%至50%。通常，更换台面可使剂量降低3%至15%，更换暗盒前部可使剂量降低6%至12%，使用带有碳纤维覆盖物和纤维间隔的滤线栅可使剂量降低20%至30%。碳纤维组件较高的成本通常可通过如此节省的剂量来证明是合理的。制造商应提供所有此类组件吸收情况的说明。
