Dynamic contrast enhanced MRI (DCE-MRI) has shown to be
promising for quantitative assessment of complex ovarian
cancers. Quantification of DCE-MR images could be
affected by motion artifacts and intensity inhomogeneity
induced by bias fields. Proper selection of a
registration algorithm could impact the outcome of this
problem. In this work, we proposed an efficient
non-rigid registration method in a group-wise setting to
non-rigidly align DCE-MR images to reliable
quantification of ovarian masses.
