Anisotropic 3D reconstruction and restoration for rotation-scanning 4D echocardiographic images based on MAP-MRF

Abstract

An anisotropic method of 3D reconstruction method for time sequence echocardiographic images is proposed in this paper. First, a Bayesian model based on MAP-MRF is described to reconstruct 3D volume, and extended to deal with the images acquired by rotation scanning method. Second, the spatial and temporal nature of ultrasound images is taken into account for the selection of parameter of energy function, which makes this statistical model anisotropic. Hence not only can this method reconstruct 3D ultrasound images, but also remove the speckle noise anisotropically. Finally, we illustrate the experiments of our method on the synthetic and medical images and compare with the isotropic reconstruction method. © Springer-Verlag Berlin Heidelberg 2005.
