调制传递函数在扫描数字射线探测器中的应用

The detective Modulation Transfer Function applied to scanned digital radiographic detectors

D. J. Miller, A. Papanestis

摘要:

传统的调制传递函数(MTF)的扩展,检测MTF,提出了用于评估的X射线成像探测器的分辨率与非均匀的效率上的单个探测器元件的规模。的dMTF示出,以提供更好的表示比MTF的改进的分辨率报告时,读出的检测器被增强。

英文摘要:

An extension of the traditional modulation transfer function (MTF), the detective MTF, is proposed for the evaluation of the resolution of X-ray imaging detectors with non-uniform efficiency on the scale of individual detector elements. The dMTF is shown to give a better representation than does the MTF of the improved resolution reported when the readout of the detectors is enhanced.
