Free-form deformation registration has been widely used but would lead to unwanted bias in the registration of different b-value images to b0 image, especially high-b-value images, due to signal attenuation dependent on b values. We use fitting accuracy to guid free-form deformation registration. The results of our proposed method can well realign the different b-value images in liver edges and improve the fitting accuracy.
