The Near Field Ultrasound Phantom provides a means of assessment for 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. The Model 050 has a series of wire targets that appear as bright dots or lines on the ultrasound image. The targets are made from stainless steel with a diameter of 0.1 mm. There are also two known volumes, a 10 mm anechoic/+15 dB mass and anechoic focal lesions embedded within the phantom. The ¡°masses¡± are made from Zerdine? with a different contrast and attenuation relative to the background material.
