Model 512
Contrast Detail Resolution Hydrogel (water)-based
|
|
The Models 512A and 512B Contrast Resolution phantoms are composed of a hydrogel-based tissue-mimicking material.
The phantoms are constructed in an acrylic housing. |
A soft polyurethane film with an impedance closely matching human skin is used, thereby allowing easy transmission of the ultrasound beam into the phantom.
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 contain three target sizes at eight levels of contrast, ranging from -3 to +12 dB/cm/MHz relative to the background material.
The difference between the models is the size of the targets. The Model 512A contains 2, 4 and 8 mm cylindrical targets. Whereas, the Model 512B contains cylindrical targets of 5, 10, 20 mm. One year warranty. |
