The Model 049 and 049A

Elasticity QA Phantoms are

tools developed for sonoelastography

systems. These are

the only phantoms commercially

available for sonoelastography

quality assurance.

The phantom contains targets

of known stiffness relative to

the background material and

range in stiffness, diameter

and depth.

The Elasticity QA Phantoms

are suitable for determining

the dynamic range of the

system, checking system

performance over time, demonstrating

system features

and training personnel and

customers on this rapidly

growing field. The phantoms

can also be used by researchers

developing and verifying

new techniques.

The Model 049 is a basic QA

phantom as it contains two

sizes of spheres positioned at

two different depths. At each

depth there are two spheres

that are softer than the

background and two that are

harder than the background.

For a broader range of target

sizes, the Model 049A is now

available. The Model 049A

has stepped mass targets

instead of spheres. Each

stepped mass consists of six
