Paper Abstract

Scattered radiation reduces image contrast and is probably the biggest factor contributing to poor diagnostic quality in radiography. In conventional radiography, X-ray grids are widely used to improve the diagnostic quality of radiographs by absorbing the great part of scattered radiation. In digital radiography the decoupling of the image acquisition and display allows potential image processing solutions to remove the effects of scatter. In this work, we present novel scatter and grid models that are constructed to aid in finding potential solutions for scatter reduction that do not entail the degree of tradeoff between scatter removal and dose as in conventional radiography.
