NEAR FIELD ULTRASOUND PHANTOM MODEL 050 - QA STANDARD FOR HIGH FREQUENCY PROBES

Near Field
Ultrasound Phantom

QA standard for high frequency probes

Model 050

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.

At normal or room temperatures the Zerdine?(1) material found in the Near Field phantom will accurately simulate the ultrasound characteristics found in human tissue.

The Model 050 has a series of wire targets that will appear as bright dots or lines on the ultrasound image. These targets are made from stainless steel with a diameter of 0.1 mm. There are also two known volumes, a 10 mm combination cyst-like/hyperechoic mass and anechoic focal lesions embedded within the phantom. These “masses?are made from Zerdine?that has a different contrast and attenuation relative to the background material.

The Model 050 was designed to allow for assessment of uniformity, dead zone, depth of penetration, beam profile/focal zone/lateral response width, vertical distance measurement accuracy, axial resolution, lateral resolution, anechoic masses, high contrast masses, volumetric measurement accuracy, and focal lesion detectability.
