Ultrasound Precision Resolution Gray Scale Phantom

Advanced tissue mimicking gel and grey scale targets are designed for the exacting standards of todays high-resolution ultrasound systems. The Precision Resolution Grey Scale Phantom 405GSX LE incorporates our new Tissue Mimicking (TM) gel which provides a smoother background texture than conventional tissue mimicking gels.

Tissue Mimicking gels are fully compatible with the latest in tissue harmonics equipment and technology. The phantom can be scanned using normal control settings and ensures that the performance measured closely approximates the scanner’s performance in a clinical examination. In addition, the phantom has a new composite film scanning surface that has improved transmission properties so more of the ultrasound beam can be transmitted and received.

The Precision Resolution Gray Scale Phantom contains all of the quality indicators for performing evaluations of axial resolution, lateral resolution, dead zone cyst imaging, vertical and horizontal distance accuracy and image uniformity. The Precision Resolution Grey Scale Phantom also contains triangular grey scale targets which test the resolution of today’s high-performance ultrasound scanners. Unique to the 405GSX LE are two horizontal cross fibers located in the middle of the phantom. These fibers help the user align the transducer and can be used as a reference “marker” to ensure that QA tests are consistently performed on the same scan slice. When both fibers are illuminated, the user can be certain the transducer is exactly perpendicular to the scanning surface.

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