Abstract
A phantom for evaluating resolution of a nuclear imaging system has the form of a rectangular sealed container filled with liquid to simulate clinical scattering. The container surrounds five interior steps extending across its width in a linear depth progression. Identical groupings of lead disks are placed on each step. Each grouping includes several subgroups of disks arranged across the step in a linear progression of width sizes and spacings.
