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 two experimentally determined parameters unique to a given image intensifier. This information is utilized to deconvolve the degradation from digitally acquired images. Results demonstrate a significant increase in contrast ratio of high‐contrast objects after deconvolution and image restoration.
