Ultrasound Dual Attenuation Phantom 406LE

The Dual Attenuation Phantom 406LE gives you the benefit of having two phantoms in one with background attenuations of 0.5 and 0.7 dB/cm/MHz in a side-by-side configuration. Quality control tests over a wide range of frequencies can be performed quickly and easily, providing a comprehensive profile of the scanner’s overall image quality – all with a single phantom.

The Dual Attenuation Phantom 406LE is a highly effective instrument for demonstrating superior image quality while challenging high performance ultrasound systems. The phantom incorporates our Tissue Mimicking gel which provides a smoother background texture, and a composite film scanning surface that has improved transmission properties so more of the ultrasonic beam can be transmitted and received.

With extended target depths to 16 cm, this phantom provides greater scanner and transducer performance tests of resolution, depth of penetration and electronic caliper measurements. Extra pin targets are ideal for testing high frequency transducers which are designed to image the first few centimeters of human tissue. Resolution patterns and all vertical and horizontal targets are constructed of 0.1 mm nylon fiber. Three sets of axial resolution targets at 3, 8 and 14 cm, and spaced at 2.0, 1.0, 0.5 and 0.25 mm, make this phantom extremely effective for demonstrating high resolution detail and challenge the ultrasound system’s resolution capability. Scatter-free cylinders of 2, 4 and 6 mm diameter are embedded in the phantom representing blood vessels in human tissue.

Optional accessories for the Dual Attenuation Phantom 406LE include Soft Foam-Lined Carrying Case, Rigid Case, or the Precision Ultrasound Transducer Guide.
