Abstract:
A method for displaying an element having a periodic structure, images of which are acquired by means of a radiography device of the type comprising means for providing a source of radiation and means for detection and display placed opposite the source, comprising:displaying images obtained with an overall magnification of: fSfC&it;â€ƒ&it;S&it;â€ƒ&it;FÃ—E&it;â€ƒ&it;S&it;â€ƒ&it;DÃ—Ï€180,where fS is the fundamental frequency, being the inverse of the spatial period of the element in pairs of lines per millimeter; where fCSF is a spatial frequency corresponding to the contrast sensitivity maximum for the human eye in cycles per degree; and where ESD is the expected distance in millimeters between the means for displaying the images and an observer viewing these images.
