General Purpose
Multi-Tissue
Ultrasound Phantom

The standard for ultrasound quality assurance
Two Phantoms in one case

Model 040


The CIRS series of ultrasound phantoms, unlike human subjects or random scannable materials, offers a reliable medium which contains specific, known test objects for repeatable qualitative assessment
of ultrasound scanner performance over time.

This phantom is constructed from the patented solid elastic material,  Zerdine® (1). Zerdine, unlike other phantom materials on the market, is not affected by changes in temperature.  It can be subjected to boiling or freezing conditions without sustaining significant damage.  Zerdine is also more elastic than other materials and allows more pressure to be applied to the scanning surface without subsequent damage to the material.  At normal or room temperatures the Zerdine material found in the Model 040 will accurately simulate the ultrasound characteristics found in human liver tissue.

The Model 040 was designed  to allow for assessment of  uniformity, axial and lateral resolution, depth calibration, dead zone measurement, and registration within two different backgrounds of 0.5 and 0.7 dB/cm/MHz.
