Abstract

Following identification of an image artefact on a newly commissioned mammography system, the grid was initially not suspected as the cause as grid artefacts are generally associated with lines.  A reference phantom image was taken at an accredited centre was used to resolve the problem.  It is therefore felt to be essential for instructions not subject to peer evaluation to use phantoms.
