Model 408 – Spherical Lesion Phantom – Sun Nuclear

This Spherical Lesion Phantom from Sun Nuclear (formerly Gammex) 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.

Spherical Lesion Phantom 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.
