Due to the large amount of noise present in echocardiographic images, the interpolation used to get 3D images can yield indesirable results. The authors introduce a 3D finite volume method for image selective smoothing directly in the cylindrical image geometry. A semi-implicit 3D cylindrical finite volume scheme for solving a Perona-Malik-type nonlinear diffusion equation is studied. The authors apply the scheme to 3D cylindrical echocardiographic images.
