The Gammex 159A and 159A-BR Mammographic Phototimer Consistency Test Tools are designed to test Automatic Exposure Control (AEC) performance.
Phototimer consistency test tools come in either:
• 7 pieces of acrylic (159A), or
• 7 pieces of breast tissue equivalent material (159A-BR)
With this test tool, different thicknesses can be imaged and densities measured to confirm that the automatic exposure control/phototimer is operating at an optimum level.
