WebA fine or broad focus can be chosen depending on various imaging factors. The patient should be placed as close as possible to the detector which helps reduce effects of magnification, whilst minimising movement-induced artefact. It also helps to maintain image contrast by reducing the effect of scattered radiation reaching the detector.
