Abstract
Medical image registration plays an essential role in subsequent image processing and analysis. The demand of direct 3D registration of volumetric image data has been arisen due to the increasing amount of medical image data. This paper investigates a fast volumetric image registration algorithm based on an incompressible viscous fluid model. While direct extension and implementation from 2D fluid registration is inaccessible, we develop numerical techniques to accelerate the computation based on the alternating direction implicit (ADI) scheme. In consequence, the computational complexity is significantly reduced from O(N3) to O(N). Not only does the computation time expedite, but the memory usage is also cut down. Massive experiments with both simulated and clinical magnetic resonance (MR) image data were administered to qualitatively and quantitatively evaluate the proposed 3D image registration framework. Experimental results suggested that our accelerated image registration algorithm produced high accuracy on both 2D and 3D image registration scenarios and outperformed competing methods. We believe that the proposed volumetric image registration scheme is promising in processing MR image volumes for further medical applications. ? 2021 European Signal Processing Conference, EUSIPCO.
