Abstract
The definition of the blurring of narrow beam rotation radiography is revived. The relative value of the blurring is considered to be the most reliable measurement. Calculations of the layer thickness should be based on the definition of the relative blurring. Experimental tests were performed, which confirm the mathematically presented hypothesis and also confirm the validity of the mathematical model of narrow beam rotation radiography presented by WELANDER (1974).
摘要
窄束旋转射线照相模糊度的定义得以重新探讨。模糊度的相对值被认为是最可靠的测量方法。层厚的计算应基于相对模糊度的定义。进行了实验测试，这些测试证实了数学推导的假设，也证实了韦兰德（1974年）提出的窄束旋转射线照相数学模型的有效性。
