Registration of the MALDI–MSI image onto the MRI image. Registration of the segmented MALDI–MS image onto the a denoised MRI image: b linear registration followed by c the variational method of Modersitzki [21] or d, e free form deformation models with two different parameters (\(\text {FFD}_1\) and \(\text {FFD}_2\)). e The circled area (in red) shows a difference in shape compared to the MRI image
