The Model 531 Grayscale phantoms is designed to test an imaging system’s gray scale processing and displayed dynamic range. The phantom provides a set of ten different greyscale targets, each 10 mm in diameter, that range in greyscale brightness contrast from -15 to +15 dB relative to the background material. All ATS urethane phantoms are guaranteed for the useful life of the phantom, defined as 10 years.
