Retrospective correction of the heel effect in hand radiographs
A method for the retrospective correction of intensity inhomogeneities induced by the heel
effect in digital radiographs is presented. The method is based on a mathematical model for
the heel effect derived from the acquisition geometry. The model parameters are estimated
by fitting the model to the image intensity data in the background or direct exposure area
only where the heel effect is directly measurable, while the correction is then applied to the
whole image. The method iterates between background segmentation and heel effect …
