A Study on Robustness of Various Deformable Image Registration Algorithms on Image Reconstruction Using 4DCT Thoracic Images
Background: Medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. To do this, deformable image registration algorithms are mainly utilized to perform image interpolation using tomography images.Materials and Methods: In this work, 4DCT thoracic images of five real patients provided by DI...
متن کاملDeformable registration of 4D-CT lung image using landmark
Landmark based image registration algorithms have been applied to medical image analysis widely. While estimation of the correspondence between landmarks among images are the most important and difficult problem. In this paper, novel landmarks based image registration method combining local tracking and global adjustment of landmarks in 4D-CT lung images is proposed. In order to accurately esta...
متن کاملDeformable Registration of CT Pelvis Images Using Mjolnir
Our recently published 3D-3D deformable image registration algorithm, Mjolnir (Ellingsen et al., 2006) was developed for inter-subject registration of MR brain images. Mjolnir is a hybrid registration method, where both anatomical features and image intensities are used to hierarchically align the images. In addition to the hierarchical scheme, the algorithm was implemented in a multi-resolutio...
متن کاملEvaluation of deformable registration of patient lung 4DCT with subanatomical region segmentations.
Deformable registration is needed for a variety of tasks in establishing the voxel correspondence between respiratory phases. Most registration algorithms assume or imply that the deformation field is smooth and continuous everywhere. However, the lungs are contained within closed invaginated sacs called pleurae and are allowed to slide almost independently along the chest wall. This sliding mo...
