Removal of image intensifier veiling glare by mathematical deconvolution techniques
J. A. Seibert, O. Nalcioglu, W. Roeck
Source 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 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.
