Approaches of Multimodal Medical Images Registration and Fusion: Efficacy on Diagnostic and Therapeutic Planning
Dwijesh Dutta Majumder, Dipankar Ray · IETE Journal of Research · 2011
AbstractMedical images of different modalities, such as computed tomography/magnetic resonance/Positron Emission Tomography/Single Photon Emission Computed Tomography/ultrasonography, etc., of a particular object of interest provide complimentary information about the conditions of diseases and that of patients. Mapping of one image over that of other and a subsequent fusion of images is of immense importance from the point of view of diagnostics and treatment planning. In this paper, we have presented major theoretical/practical approaches of medical image registration. After making both methodological and technical survey of almost all the approaches in literature of both functional and anatomical images, we presented an in-depth study of two relatively recent approaches that we consider most promising. These are shape theoretic and image entropy-based methods. We have also proposed a soft computing approach of fusion of registered images using Dempster Shafer Theory of Evidence Accumulation along with ...
