Increasing sensitivity roentgenogram analysis by means of automorphic mapping method in a basis of eigen images.

A. M. Akhmetshin, L. G. Akhmetshina

ABSTRACT

         A new method increasing sensitivity and space resolving power visual analysis of low contrast radiological medical images is outlained. Unlike from known methods of inverse fuiltering, the new method does not requier apriory knowledge the transfer function of image system for¬ming and it can be applied to space–invariant and to space–noninvariant systems. Experimental results information possibilities of the method are presented.

Keywords: automorphic map ing, sensitivity, resolving power, low contrast, eigen image.
