- At the center of the phantom are pie shaped wedges of varying mesh sizes: 20#, 30#, 40#, 60#, 80#, and 100# L/in, for evaluating high-contrast performance
- Surrounding the mesh are four low contrast “masses” of different diameters: 2, 4, 6, and 8 mm
- At one edge of the phantom is a small “density difference” patch, for a measure of contrast on the films
- At the opposite edge of the phantom are two monitor adjustment squares, each having a low contrast square insert
- The phantom contains a 2 mm copper attenuator, which allows it to simulate the attenuation of an average adult
- At the corners of the test tool are lines for aligning the light field
- QC charts are provided for plotting both the radiographic and fluoroscopic results
- Along the sides of the test tool are beads 1 cm inside and outside of the lines started in the corners
