title: Niobium/aluminum filters reduce patient exposure.
abstract: Reducing patient exposure while maintaining image quality is key to radiographers. In a comparison study of different filters, the authors found that a combined niobium/aluminum filter provides substantial reduction of entrance skin exposure with fairly small increases in tube loading and little loss of image contrast.
