Dynamic Heart and Lung Phantom

This phantom represents movement of the heart, lungs and pulmonary nodule. The pulmonary nodule and the diaphragm move independently with the respiratory cycle. A three dimensional movement of the pulmonary nodule (linearly and rotationally) can be simulated. The respiratory movement of the abdomen is simulated as well as systolic and diastolic movement of the heart. Coronary arteries including stenotic examples are shown. The phantom can be connected to an ECG for ECG gating. The phantom can be used for respiratory gated chest CT, tumor tracking in radiotherapy and ECG gated cardiac CT.
