Contrast Detail Resolution Ultrasound Phantoms
Models 532A and 532B
Product Description
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.
Tests Performed

|
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 5, 10 and 20 mm diameter cylindrical targets.
