The Gammex 406 LE Dual Attenuation Phantom 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 406 LE phantom 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 Gammex line of Ultrasound phantoms include Soft Foam-Lined Carrying Case, Rigid Case, or
the Precision Ultrasound Transducer Guide.
