Deformable registration process for in vivo human spine MR images can provide the crucial information to investigate the diagnostic performance and treatment effects of pathologies. Here, based on the scale invariant feature transform (SIFT) algorithm, we attempted to evaluate the deformable registration process for spine images, and compared with commercially mounted algorithm in MRI system. The results qualitatively and quantitatively showed fine results, and clearly showed the reproducibility of the use of SIFT algorithm compared with commercially mounted stitching algorithm on MRI system. Our approach can be helpful for the extension of other medical imaging modalities for image deformable registration.
