The Multi-Purpose Gray Scale Phantom 403GS LE offers new advanced technology for measuring the image quality of high resolution ultrasound systems. Gray scale targets are provided for monitoring contrast and temporal resolution, distinguishing different intensities of brightness and border delineation capabilities of the ultrasound system. The 403 LE has the same general target layout and specifications as the 403GS LE but does not include grey scale targets.

The Multi-Purpose Gray Scale Phantom offers carefully placed targets to measure resolution, depth of penetration and electronic caliper distance accuracy. Axial resolution resolution tests. The resolution patterns as well as all vertical and horizontal targets are constructed of 0.1 mm nylon fibers for better detail definition and spatial resolution. Grey scale targets are set at -6 dB, +6 dB with high scatter relative to the background material and with attenuation properties equivalent to the Tissue Mimicking (TM) material. A 10 mm anechoic cyst is also provided to evaluate system noise and geometric distortion.

The 403GS LE and 403 LE phantoms incorporate our new Tissue Mimicking (TM) gel which provides a smoother background texture than conventional tissue mimicking gels. This gel reduces the backscatter that is inherent in other TM gels and is fully compatible with the latest in tissue harmonics equipment and pin spacing patterns are small, offering better axial technology. The 403GS LE also has a composite film scanning surface that has improved transmission properties so more of the ultrasonic beam can be transmitted and received.

Optional accessories for the Multi-Purpose Gray Scale Phantom include Soft Foam-Lined Carrying Case, Rigid Case, or the Precision Ultrasound Transducer Guide.
