3D image deformation for medical image registration generally is a time-consuming task. This drawback slow down the image registration speed. Thin - Plate Spline (TPS) is an commonly used interpolation technique to deform images which assure the least bending energy. This paper proposes a parallel implementation of 3D image deformation using Thin-Plate Splines and tri-linear interpolation which is...
Lung motion estimation plays an important role in image-guided radiotherapy. This paper presents an algorithm to estimate lung deformation and motion during respiration using 4D deformable image registration for 4D-CT data. The image intensity of 4D-CT is transformed into vessel feature space, which is used to extract and track bifurcation points of lungs vessel. The spatially mean shift iteration...
The skeletons of the objects in 3D images can be extracted by using 3D image thinning. The application of 3D image thinning for image analysis is hampered by its considerable computation time. By employing the graphics processing unit (GPU), which has tremendous powerful computing power at an incomparable performance-to-cost ratio, the calculation of 3D image thinning can be accelerated. In this paper,...
