Therefore, the actuator components of the phantom consisted exclusively of shape memory wires. It should be possible to compare newly developed and existing gating systems in a breathing frequency range from 0,2 Hz to 1,2 Hz with the phantom. For this purpose, an artificial muscle was developed to simulate the respiratory support muscles in the back, which was investigated for its temperature-dependent contraction behavior using a temperature and angle measurement. This made it possible to determine the optimal operating point for controlling the artificial muscle. For the control of the repsiratory movement of the chest and abdomen, tests were performed on an existing gating system. It was shown that the thorax phantom can successfully reproduce respiratory motions in the lower respiratory frequency range. At higher respiratory frequencies, the quality of the respiratory signal decreased significantly in the performed tests, depending on the gating system. A final test performed with an existing gating system on a computer tomograph was successful.}, subject = {Thorax}, language = {de} }
