Contrast Detail Resolution Ultrasound Phantoms ATS 532A & 532B
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/cm/MHz 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.
The Model 532B contains cylindrical targets 5, 10 and 20 mm in diameter.
