Abstract
The present invention provides an image registration device and method, an image segmentation device and method and a medical image apparatus. The image registration device includes: a rigid registration unit for performing a rigid registration of a first input image with a second input image, which is a reference, to obtain first deformation information; a first non-rigid registration unit for performing a first non-rigid registration of the first and second input images by taking the first deformation information as the initial deformation information to obtain second deformation information; and a second non-rigid registration unit for performing a second non-rigid registration of the first and second input images by taking the second deformation information as the initial deformation information to obtain third deformation information. By combining rigid registration with non-rigid registration, the present invention realizes a fast image registration.
