The Model 049 Elasticity QA Phantom contains 10 mm and
20 mm diameter spheres of varying hardness relative to the back-ground material. The spheres are located at depths of 15 mm and 35 mm respectively and will appear almost isoechoic to the background using standard B-mode imaging.
All materials are tested at CIRS and a data sheet is provided listing the acoustic and elastic properties of each tissue.
Housed in a durable ABS housing with flexible scanning surface, the Model 049 is manufactured from Zerdine® (1) - a solid-elastic polymer whose elastic properties can be controlled independently of its acoustic properties. The phantom is a reliable and consistent elasticity reference tool useful for researchers, sales demonstrations and quality assurance testing.
