Spatial and temporal shape constrained deformable surfaces for 3D and 4D medical image segmentation

4D deformable models with temporal constraints: application to 4D cardiac image segmentation

Segmentation of time series of 3D cardiac images is clinically used for the assessment of the mechanical function of the left ventricle. To take into account the 4D (3D+T) nature of those images, we propose to extend the deformable surface framework by introducing time-dependent constraints. Thus, in addition to computing an internal force for enforcing the regularity of the deformable model, p...

A Novel Deformable Model for Medical US Image Segmentation

Medical ultrasound (US) images are characterized by inherent noise perturbations which introduce uncertainty in their interpretation even by experienced radiologists. In this paper we propose a novel deformable model for medical US image segmentation, which incorporates a combination of domain and boundary integrals for the alleviation of the noise effects. It can be applied as a diagnostic aid...

An electrostatic deformable model for medical image segmentation

A new deformable model, the charged fluid model (CFM), that uses the simulation of charged elements was used to segment medical images. Poisson's equation was used to guide the evolution of the CFM in two steps. In the first step, the elements of the charged fluid were distributed along the propagating interface until electrostatic equilibrium was achieved. In the second step, the propagating f...

An Unsupervised Learning Model for Deformable Medical Image Registration

We present an efficient learning-based algorithm for deformable, pairwise 3D medical image registration. Current registration methods optimize an energy function independently for each pair of images, which can be timeconsuming for large data. We define registration as a parametric function, and optimize its parameters given a set of images from a collection of interest. Given a new pair of sca...
