The Models 532A and 532B Contrast Resolution phantoms are composed of a rubber-base tissue-mimicking material. These models are provided with a built-in scanning well to permit the use of water or a low viscosity gel as a coupling medium.
The Contrast Resolution phantoms are designed to evaluate an imaging system’s gray scale processing and displayed dynamic range. Both models provide three target sizes at eight levels of contrast, ranging from -12 to +12 dB relative to the background material. The difference between the models is the size of the targets. The Model 532A contains 2, 4 and 8 mm diameter cylindrical targets. Model 532B contains cylindrical targets 5, 10 and 20 mm in diameter. All ATS urethane phantoms are guaranteed for the useful life of the phantom, defined as 10 years.
