  • Whole body image registration method and method for analyzing images thereof
    Patent number: 10083506
    Abstract: A method for registration of whole body volume images comprises obtaining (210) of a first image and a second image, comprising water and fat whole body magnetic resonance image data. Bone tissue are identified (220), creating respective bone images. Water components are separated (230), generating respective water images based on absolute water content. Fat components are separated (240), generating respective fat images based on absolute fat content. The first image is registered (250) to the second image by deforming the first bone image according to a bone tissue deformation rule, deforming the first water image according to a water tissue deformation rule under constraints of the first bone image deformation and deforming the first fat image according to a fat tissue deformation rule under constraints of the first bone image and the deformation of said first water image. Also, a method for analyzing the registered images is provided.
