Abstract :
The aim of this work is to present an advanced motion correction pipeline for dual gating based on motion compensation. The pipeline is robust against noise and uses the whole statistic for the final image. We extend motion compensation by motion compensated reconstructions which allow a much finer dual gating for maximal reduction of motion artifacts. Further, mass-preserving motion estimation based on spline transformations is performed motion estimation.
