1.1 Introduction
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 Podiatry Filters are translucent 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 should be used with a rare-earth film screen combination to improve image quality.
Consult your film manufacturer for the proper combination. CLEAR-Pb may also be used with positive
Polaroid instant radiographic film.
