The phase-contrast radiography is an edge-enhancement technique which allows to visualize objects providing very low contrast with the conventional absorption radiography technique. The image formation in this case is based on the phase variations transformed to intensity variations in a beam with a
## Abstract A new technique for multistep phaseβcontrast image processing is presented. The __N__βstep method consists of simply forming the linear average of the __N__ β 1 adjacent phaseβdifference signals. It has similar noise reduction properties as other multistep techniques, but the simplicity
