408 LE provides a unique and soon to be automated way of testing resolution performance of ultrasound scanners. The Spherical Lesion phantom contains 2mm and 4mm diameter tissue mimicking spherical lesions.
Lesions lie in a single plane at the center of the phantom.
Axial, lateral and elevational resolution are accounted for simultaneously and equally for all types of ultrasound systems and configurations. In the 2mm section, there are 105 anechoic spheres at 0.5 cm depth intervals and in the 4mm section there are 211 anechoic spheres at 0.75 cm depth intervals. This array of anechoic spheres allows for the use of software to perform automated analysis of the ultrasound system's performance. This gel allows production of lesions with negligible echogenicity while producing no distal enhancement or shadowing inherent with other gel forms. The new TM gel is also optimized for use with Tissue Harmonics Imaging technology.
