Abstract

Intensifying screens are a significant source of blur in most medical x-ray imaging systems. In the analysis of x-ray system performance it is desirable to specify intensifying screen blur in terms of a single parameter which can be easily combined with focal-spot blur. This is achieved by describing screen performance in terms of equivalent blur, which is defined as the dimension of a square blur pattern which has a uniform intensity distribution. This paper describes a simple method for obtaining equivalent blur values from the MTF of intensifying screens and gives the values for representative screens.
