Precision Multi-Purpose Phantoms, Gammex 403GS LE and 403 LE

Precision Multi-Purpose Phantoms

Gammex 403GS and 403 LE

Product Overview

The 403GS LE Multi-Purpose Phantom provides advanced technology for measuring image quality of small parts and intra-cavity ultrasound scanning systems.  Grey scale targets are provided for monitoring contrast and 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 it does not include grey scale targets.

Both phantoms incorporate the latest Gammex Tissue Mimicking gel technology to provide a smoother background texture than what is provided by conventional tissue mimicking gels. 

Benefits

  • Scanning of phantom using normal control setting ensures that the performance measured closely approximates the scanner's clinical performance.
  • Permits full monitoring of the ultrasound system including:
    • evaluation of axial resolution 
    • evaluation depth of penetration,
    • electronic caliper distance accuracyxx
  • Grey scale targets test the resolution of high-performance scanners on the 403GS LE
  • 0.1 mm nylon fibers give better detail definition and spatial resolution.
  • Convertible water dam for gel or water coupled scanning 
  • Compact design
  • Economical

Features

  • The phantom utilizes the unique Tissue Mimicking gel of Gammex
  • Combination of anechoic cyst, grey scale and pin targets to permit a wide range of testing.
  • Convertible water dam 
  • Measure to depths of up to 16 cm 
  • -6 dB, +6 dB and high scatter grey targets on the 403GS LE 
  • Resolution patterns and all vertical and horizontal targets are made of 0.1 mm nylon fibers
  • Low scatter cysts of 2, 4, 6 and 10 mm diameters to evaluate system noise and distortion
  • Available in 0.5 and 0.7 dB/cm/MHz attenuation

Warranty

  • Each phantom comes with a 1 year Warranty
  • Extended Warranty plans are available.
