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.  
  
Gammex TM 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 405GSX LE 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 Gammex line of Ultrasound phantoms include Soft Foam-Lined Carrying Case, Rigid Case, or 
the Precision Ultrasound Transducer Guide.
