General Description
1.1 University at Buffalo (UB) Gamma Test Pattern
The University at Buffalo (UB) Gamma Camera Test Pattern is a plastic plate with precisely machined
parallel lines, filled with a high-density eutectic metal. The 20” x 20” x 3/8” pattern consists of machined
sets of equally spaced parallel lines in an “L-shaped” configuration in each quadrant of the unit. Each
quadrant contains four equally spaced parallel line frequencies: 1/10”, 5/32”, 3/16”, and 1/4“. This pattern
allows the visual evaluation of spatial resolution and linearity for routine quality control testing using only
one camera image acquisition. The UB Test Pattern provides the same information as a 90º bar quadrant
pattern but at a quarter of the imaging time.
