Overview: This paper introduces a fast non-rigid registration method for aligning pre-operative 1.5 T MR Images to intra-operative 0.5 T MR Images for guidance in prostate biopsy. After the acquisition of both pre-operative 1.5 T and intra-operative 0.5 T, an intensity correction method is applied to the pre-operative images to reduce the significant artifacts in the signal intensities due to the presence of an endo-rectal coil. A fast manual segmentation of prostate in both modalities is carried out to enable conformal mapping of the surface of the pre-operative data to the intra-operative data.
