1.2 Description
A schematic drawing of the Phantom is shown in Figure 1-1. At the center of the Phantom are pie-shaped
wedges of varying mesh sizes: 20#, 30#, 40#, 60#, 80# and 100# for evaluating high contrast
performance. Surrounding the mesh are four low contrast "masses" of different diameters: 2 mm, 4 mm, 6
mm 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 copper attenuator in the Phantom allows the Phantom to
simulate the attenuation of a small adult. At the corners of the Phantom are lines for aligning the light
field.
