57-430 Thin Build Up Filter Clear-Pb® &
57-434 Thick Build Up Filter Clear-Pb®
Build Up Compensation Filters are made of a lead-plastic material that is 30% lead by weight. Since lead is an efficient absorber of x-rays, the filters will attenuate the x-ray beam. By varying the shape and thickness of the filters, many combinations of filtering action can be achieved from almost complete attenuation to full penetration.
CLEAR-Pb® Filters should be used with a rare-earth film/screen combination to improve image quality and keep patient exposure to a minimum. CLEAR-Pb® Compensation Filters are not compatible with gradient speed intensifying screens. Consult your film manufacturer for the proper film/screen combination.
