Three Dimensional
Ultrasound Calibration Phantom

The perfect tool for assessment of
volumetric measurement accuracy

Model 055




The Model 055 was designed to allow for assessment of volumetric measurement accuracy and 3D imaging.

The background is calibrated to mimic the ultrasound characteristics of human liver tissue. The phantom contains two calibrated volumetric test objects. The test objects and background material are made from Zerdine® a patented, solid elastic material. Unlike other phantom materials Zerdine is not damaged by changes in temperature.

The Model 055 is completely encased within a rugged ABS container which minimizes desiccation and facilitates scanning on two sides enabling 3D scanning.

There are two embedded test objects – a small egg and a large egg. The targets are off centered within the background material. Depending upon what side is scanned, the test objects are located at distances ranging from 2 cm to 6 cm from the scanning surface.
The backscatter within the test objects is 9 dB ± 3 dB less than the background material. The speed of sound within both the background and the test objects is 1540 m/s ± 6 m/s.

The attenuation coefficient in both the background and test objects is 0.50 dB/cm/MHz ± 0.05 dB/cm/MHz. The volume of each test object is recorded on a certification sheet which accompanies each phantom.

The Model 055 3D Calibration Phantom is the tool for routine quality assurance of three dimensional ultrasound systems, software development, and research.
