Phantoms
Quality Assurance Evaluations should be done with phantoms
and test objects that are applicable to the parameters being
evaluated or to the operator's clinical practice.
Typical phantoms are composed of material that acoustically
mimic human tissue. Pins, anechoic and echogenic targets are
physically positioned to provide information for a variety of tests.
The RMI 403GS phantom is shown in the illustration below as a
representative example of a phantom.
