Dentistry—Test method for determining radio-opacity of materials
Standard in brief
Scope of Application:
本标准规定了用一种标准铝板作为标准品,以测定材料X射线阻射性的试验方法。此方法是设计用于区别具有临床意义水平的X射线阻射性,而不考虑影响精度的因素,也不考虑影响X射线阻射性的自身因素(诸如背景噪声、X射线能量、灰度校准和图像增强)。虽然,这些影响因素能够改变X射线阻射性的数值,但是不能改变与标准厚度的标准品(例如铝)相比较的对应趋势。本试验可以通过牙科X射线机的传统或数字传感技术来完成。
