Abstract

A phantom has been designed which simulates the environment of the left ventricle in the chest. The phantom consists of 5 tubes approximating arteries with contrast, layers of acrylic plastic to simulate soft tissue, bones, and a bladder which can be inflated with a dilute contrast solution to simulate the left ventricle. The parts of the phantom can be adjusted to provide known amounts of motion in three dimensions and is used in the evaluation of a three-dimensional motion correction algorithm which is described in detail in a companion paper. Images of the phantom appear to be like those seen in x-ray imaging of the chest. The results using the phantom to test the registration algorithms show that a significant improvement in the subtraction images of the phantom can be achieved in the presence of simulated three-dimensional motion, when compared to conventional subtraction.
