Abstract

Problems of image contour spread in roentgenology are well known. They concern the influence of different apparatus, X-ray, photo, and optical parameters on the image unsharpness and on the corresponding spatial resolution [3, 14]. In conventional roentgenology, there exist different methods for decrease in image unsharpness that is, decrease in their contour spread. This fact, combined with the specific features of the X-ray image, causes spread width (the transition layer width between the images of two contiguous structures) to be normally below 1 mm, this having no substantial effect on diagnostical interpretation.
