Spherical Lesion Phantom, Gammex 408 LE

Spherical Lesion Phantom

Gammex 408 LE

Product Overview

This phantom is used to test the resolution of Ultrasound scanners.  It tests in 3 dimensions:  axial, lateral and elevational.  

The phantom contains both 2mm and 4mm diameter tissue mimicking spherical lesions which lie in a single plane at the center of the phantom.  Axial, lateral and elevational resolution are accouted for simultateously and equally for all types of ultrasound systems and configurations. 

Benefits

  • Test for Axial, lateral and elevational resolution simultaneously
  • Check for multiple diameters at both 0.5 cm and 0.75 cm depth intervals  
  • Different diameter tissue mimicking lesions permits checking of different resolutions at different depths
  • Fewer issues related to background due to the unique tissue mimicking gel used in the phantom
  • Compact design makes it easy to either store or ship
  • Economical 

Features

  • Contains both 2mm and 4mm diameter tissue mimicking spherical lesions
  • The 2mm section contains 105 anechoic spheres at 0.5cm depther intervals
  • The 4mm section contains 211 anechoic spheres at 0.75 depth intervals
  • Tissue Mimicking gel used provides smoother background texture
  • Lesions produced with negligible echogenicity while producing no distal enhancement or shadowing
  • TM gel optimized for use with tissue harmonics imaging technology
  • Composite film scanning surface provides improved transmission properties permitting more of the ultrasonic beam to be transmitted and received. 

Certification and Warranty

  • Comes with 1 year Warranty
  • Extended Warranty plans are available
