Anthropomorphic phantoms are physical test objects simulating anatomical structures of the body, which makes them easier and more convenient to use. Some phantoms provide equivalent properties as the real human body does, e.g., organs, such as lung, liver, fat, bone. This is an advantage in X-ray imaging due to dose issues – medical devices can be thus tested without using human volunteers.
Physical parameters of such devices can be tested as well in a more physical or technical way, for example the spatial resolution of a system can be tested with a wire in a cylindrical phantom to create a MTF, or with a high resolution bar pattern as well for visible testing.
