It has been shown recently that k-t PCA permits high acceleration without compromising the accuracy of single directional flow quantification. In this work 3D velocity fields are measured in a phantom and an in-vivo case and reconstructed with different acceleration factors. Pathline tracking is possible up to an acceleration factor of 10.
