Quantification of dynamic contrast enhanced MRI (DCE-MRI) is often hindered by motion during imaging. Multiple sources of motion require for a non-rigid 3D registration to align dynamic images. This study provided a rapid 3D non-rigid registration tool for DCE liver registration by optimizing the scheme of image matching. The results show that the dynamic images were well aligned in terms of whole liver area and the portal vein area. Meanwhile, the intensity plot demonstrated better representation from the registered images. Computation time of registration was about one minute for the entire scan, making it possible for clinical routine analysis.
