The line spread function and modulation transfer function of a computed tomographic scanner

Med Phys. 1976 Jul-Aug;3(4):233-6. doi: 10.1118/1.594283.

Abstract

A simple method to measure the line spread function of computed tomographic scanners has been developed. The line spread function of the EMI-Scanner was measured and the MTF of the scanner was calculated. The reproducibility of the method indicated this technique could be utilized to compare the spatial resolution of various computed tomographic scanners.
