Respiratory motion models

WebPositron Emission Tomography (PET) is an established functional imaging modality but its practical deployment is hampered by motion artefacts. This paper proposes a method for correcting reconstructed PET images through a list-mode rebinning process. Respiratory motion is compensated for by applying 2D affine transforms to the respiratory gated … Webmization of methods to adequately account for breathing motion require detailed knowledge of the dynamics and its impact on e. g. the dose delivered by radiation. Thus, computer aided modeling and model based simulation of respiratory motion gains in importance. In this paper a biophysical approach for modeling lung motion is described.
