[Registration of the image data of the Virtual Chinese Female No.1].

In this study, the authors attempt to find a solution for the image registration before three-dimensional reconstruction of digitized Virtual Chinese Female No.1 (VCH-F1) image data can be completed. On the basis of a thorough understanding of the features of the image data, the parameters were determined based on the marker outside the specimen and the least-square procedure performed on the outline offset distance between two images, prior to the completion of the image registration by means of rigid body transformation with the parameters. In the trial application of these two methods in image registration for these image data, good results were obtained, which approved of the application of the two methods for accomplishing the image registration with simpler calculation processes and easier computer processing.
