M016A Single Exposure High Contrast Resolution Phantom - CIRS
M016A Single Exposure High Contrast Resolution Phantom - CIRS
The CIRS Model 016A incorporates two 17.5 micron thick gold-nickel bar patterns (Model 019-500). These bar patterns are positioned at 90 degrees to allow assessment of resolution perpendicular and parallel to anode-cathode axis in just one exposure. The targets have 17 segments from 5 lp to 20 lp/mm and are equivalent to 25 microns of lead at 20 keV.
The patterns are permanently embedded in a thin acrylic wafer (Model 016AW) to protect them from wear or damage. The phantom body is available in two different breast equivalent materials and features a cavity for the acrylic wafer. This design enables consistent, reproducible positioning of the bar pattern at 4.5 cm above the breast support plate and 1 cm from the chest wall, centered laterally (as recommended by the American College of Radiology).
