84-350 near field ultrasound phantom

84-350 Near Field Ultrasound PhantomThe Model 84-350 Near Field Ultrasound Phantom is constructed from a patented solid elastic material called Zerdine. Unlike other phantom materials, it is not affected by changes in temperature. It can be subjected to boiling or freezing conditions without sustaining significant damage. It is also more elastic than other materials and allows more pressure to be applied to the scanning surface without subsequent damage to the material.ApplicationsAt normal room temperature, Zerdine will accurately simulate the ultrasound characteristics found in human breast tissue. The phantom contains low-scatter masses in a range of sizes and depths, a calibrated volumetric test object, and an assortment of nylon monofilament target groups. It was designed to allow for assessment of linearity, axial and lateral resolution, depth calibration, dead zone measurement, volumetric calibration, and registration. The phantom is protected by an acrylic case and plastic membrane to facilitate scanning and minimize desiccation.
