Single Exposure High Contrast Resolution Phantom

Model 016A
PERFORM QC INSPECTIONS OF MAMMOGRAPHY SYSTEM RESOLUTION WITH JUST ONE EXPOSURE!

The CIRS Model 016A incorporates two 17.5 micron thick gold-nickel alloy bar patterns. 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 or 2.6 mm of aluminum at 20 keV.

The patterns are permanently embedded in a thin acrylic wafer (Model 016AW) to protect them from wear or dam- age.

The phantom body consists of breast equivalent materials and features a cavity for the acrylic wafer. This design en- ables 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).

Features:
  • Perpendicular bar pattern design for assessment of system resolution using single exposure
  • Reproducible positioning
  • Acrylic wafer to protect bars from wear and damage
  • Breast equivalent phantom body materials
