PHANTOM, SINGLE-EXPOSURE HIGH CONTRAST RESOLUTION Perform quality control inspections of mammography system resolution with just one exposure! This phantom incorporates two 17.5 micron-thick gold-nickel alloy bar patterns positioned at 90 degrees. This allows the assessment of resolution perpendicular and parallel to the anode-cathode axis in just one exposure! Each pattern has segments from 5 lp to 10 lp/mm and is equivalent to 25 microns of lead, or 2.6 mm of aluminum at 20 keV. The bar patterns are permanently embedded in a thin acrylic wafer, to protect them from wear and damage. The phantom body is available in BR12 or BR50/50. It enables consistent, reproducible positioning of the bar pattern at 4.5 cm above the breast support plate at 1 cm from the chest wall, centered laterally (as recommended by the American College of Radiology). The bar pattern can also be positioned at a variety of heights for more thorough evaluations. The phantom includes a 30x hand-held microscope. SPECIFICATIONS: Phantom Body: Material: BR12 or BR50/50 Dimensions: 125 mm L x 100 mm W x 20 mm H Weight: 1.3 lbs (.57 kg) Target: Material: Gold/nickel construction equivalent to 25 microns of lead, or 2.6 mm of aluminum Dimensions: 28 mm L x 8 mm W x .0175 mm H |
