title: Distortion of bar-phantom image by collimator.
abstract: Distortion of the bar-phantom scintiphoto using the medium-energy collimator may lead to the misconception that the resolution of the medium-energy collimator is better than that of the low-energy collimator. The distortion is illustrated by superposition of the transparent films of the bar-phantoms and collimator.
