Thin-Plate Spline Technique for Medical Image Deformatio

In this paper, a convenient image registration technique based on the thin-plate spline (TPS) mapping function was presented. The method can determine the corresponding medical image information and obtain the matching image structure from different images. Using this technique, the two sets of image coordinate information used as the mapping parameters obtained from the relative medical images with different imaging techniques were chosen from a developed computer user interface manually. The selected image coordinate points were used to find out the coordinate relationship of each image information to decide the mapping function. Furthermore, the deformed images and registration results can be integrated by the determined mapping function. To apply this method, it is effective to extend the image information from two-dimensional images to the three-dimensional visualization.
