新型双丝像质计设计
The Design for the New Image Quality Indicator of Duplex Wire Type
摘 要
从射线检测的一般理论，提出了新型双丝像质计设计的理论。试验证明，所提出的理论可以用于指导新型双丝像质计的设计。该像质计可克服标准型双丝像质计只能得到一些特定的不清晰度值问题，并可测量更大范围的不清晰度。

Abstract
The theory for designing image quality indicator of duplex wire type was given on the basic theory of radiography. The theory of design had been shown as ture by the experiment. The new image quality indicator of duplex wire type enabled not only to determine more wide unsharpness value than the standard type, but it cleared out also the problem that the value of unsharpness determined was only specific by standard image quality indicator of duplex wire type.
