Pulsatile test simulator for evaluating the quality of an x-ray image

摘要

A test simulator for image evaluation of x-ray systems has a flexible test phantom connected by a single connection tube with a single pump that fills and empties the test phantom with a medium. The test phantom thus contracts (as in a real heartbeat) for simulation of systole and subsequently expands for simulation of diastole. Due to the use of only one connection tube and only one pump for control, a simply designed test simulator is obtained since the pump both fills and empties the test phantom.
