Introduction
1.1 General Information
CLEAR-Pb Compensation X-Ray Filters are made of 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 Foot Filters are transparent and lightweight. By means of our "Quick-Stik" system of
magnetic strips, the filters can be held firmly in place or repositioned instantly. You can see and/or
adjust the area of filter coverage as necessary by observing the light shadow projected on the region
being radiographed. Last minute positioning checks of the patient, x-ray collimator and filters are
possible. Selected beam shaping has never been so simple and effective.
CLEAR-Pb Filters may be used with all film/screen combinations and non-screen direct exposure film
packs.
Rare-earth intensifying screens are recommended in order to further reduce patient exposure, and to
provide the best image quality. Consult your film manufacturer for the proper film/screen combination.
