Abstract
X-ray images acquired with an image intensifier detector system suffer from veiling glare, a low-frequency degradation described by a point spread function (PSF). The PSF has 2 experimentally determined parameters unique to a given image intensifier. This information is used to deconvolve the degradation from digitally acquired images. There was a significant increase in contrast ratio of high-contrast objects after deconvulution and image restoration.
