Modeling of Estimated Respiratory Waveform

In the imaging of chest or abdomen, motion artifact is a unavoidable problem. In the radiation treatment, organ movement caused by respiratory motion is a problem unavoidable also to realizing safe and effective cancer treatment preserving healthy tissue. In this article, we compare two modalities 3D CT and 4D CT and present the main difference between them, which is compensating the breathing motion. However, we record a real breathing signal using ANZAI belt, analyze the resulting signal and simulate the estimated respiratory waveform based on three different models.
