Abstract
The ability of screen-films to depict dental structures utilizing the parameters used in intraoral radiography is investigated. The resolution and contrast of a variety of screen-film combinations are determined. Radiographs made on a phantom and patient are evaluated by observers. Some film-screen combinations produce radiographs with qualities similar to conventional intraoral films and with less radiation.
摘要
研究了增感屏 - 胶片利用口腔内放射摄影所用参数描绘牙齿结构的能力。确定了多种增感屏 - 胶片组合的分辨率和对比度。由观察者对在体模和患者身上拍摄的X光片进行评估。一些胶片 - 增感屏组合所产生的X光片质量与传统口腔内胶片相似，且辐射量更低。
