Abstract
Five film-screen combinations were used to make five density-matched panoramic radiographs of a tissue-equivalent phantom skull using the Midwest/Morita Panoral x-ray machine. The radiographs were evaluated as to their diagnostic quality by twenty dental radiologists. The results demonstrate that proper screen-film selection can significantly reduce patient exposure without compromising diagnostic quality.
摘要
使用中西部/森田全景X光机，采用五种增感屏-胶片组合，对一个组织等效体模颅骨进行了五次密度匹配的全景X线摄影。20名牙科放射科医生对这些X线片的诊断质量进行了评估。结果表明，选择合适的增感屏-胶片组合可以在不影响诊断质量的情况下，显著减少患者的辐射剂量。
