Phantom imaging with a prototype phase contrast radiography system

摘要

This paper reports the results of our investigation in a phantom imaging experiments with a prototype phase contrast x-ray imaging system. Two types of phantoms, including a standard mammography phantom, and a contrast-detail phantom, were imaged, and the impact of the x-ray focal spot sizes and the magnification ratios were investigated. The images acquired with phase contrast prototype system shows better detectability as compared with the images acquired under conventional attenuation base x-ray imaging conditions.
