Title Deformable registration of whole-body fat-water MRI images
Abstract Deformable image registration is an important part of medical image analysis. Applications include longitudinal studies, population modeling, and atlas based image segmentation. However, the registration problem is a hard one and there is no one-size-fits-all solution. Imiomics is a whole-body image analysis concept combining imaging data with non-imaging data to perform various analyses. Imiomics requires a point-to-point correspondence between the images, therefore image registration is essential. A complete registration pipeline for whole-body fat-water MRI images, where bone, water, and fat are registered sequentially is presented. The core part of the pipeline being the non-parametric deformable registration algorithm based on graph-cuts. Together with a number of optimization strategies, including a block-based approach, the method is shown to produce a good result in a reasonable amount of time.
