Clear-Pb^® X-Ray Compensating Filters

CLEAR-Pb^® 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 are transparent and lightweight. Using a system of magnetic strips on the filter and a filter holder that slides into the collimator's accessory tray, the filters are held firmly in place and may be re-positioned instantly when needed. You can see and adjust the area and/or degree of filter coverage as necessary. Last-minute positioning checks of the patient, x-ray collimator, and filters are possible, thanks to the filter transparency. Selected-area beam shaping has never been so simple and effective.

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.
