%X In order to improve the efficiency of medical image registration, an image registration method based on hierarchical B-spline and parallel computing was proposed in this paper. First, landmarks were selected from the evenly distributed inner points and the outer contours of the images, and the correspondence points were automatically determined by using the parallel computing technology. Then the registration deformation was accomplished by hierarchical B-splines algorithm. Experimental results demonstrate that the method is efficient.
