Abstract:
A method of automatic determination of preferred tone-scale parameters for digital radiographic images, the method comprising the steps of:providing an input digital medical image and an associated tone-scale LUT (look-up table); using the input image and the associated LUT to determine a contrast parameter which will result in A-preferred equivalent contrast with the associated tone-scale LUT; using the input image and the associated LUT to determine a contrast parameters which will result in a preferred equivalent toe and shoulder with the associated tone-scale LUT; using the input image and the associated LUT to determine a density parameter which will result in a preferred equivalent density with the associated tone-scale LUT; and storing the preferred equivalent contrast. toe and shoulder. and density parameters for application in an algorithm emploved to produce a modified digital medical image having a preferred look.
