Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: 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.

KEYWORDS: baseline drift, Lujan model, motion artifact, fitting sine function, respiratory waveform, respiratory signal.
