Unsupervised shape and motion analysis of 3822 cardiac 4D MRIs of UK Biobank

no code implementations15 Feb 2019 Qiao Zheng, Hervé Delingette, Kenneth Fung, Steffen E. Petersen, Nicholas Ayache

First, with a feature extraction method previously published based on deep learning models, we extract from each case 9 feature values characterizing both the cardiac shape and motion.

Clustering Dimensionality Reduction +2

Explainable cardiac pathology classification on cine MRI with motion characterization by semi-supervised learning of apparent flow

1 code implementation8 Nov 2018 Qiao Zheng, Hervé Delingette, Nicholas Ayache

We propose a method to classify cardiac pathology based on a novel approach to extract image derived features to characterize the shape and motion of the heart.

Cardiac Segmentation General Classification +2

3D Consistent & Robust Segmentation of Cardiac Images by Deep Learning with Spatial Propagation

1 code implementation25 Apr 2018 Qiao Zheng, Hervé Delingette, Nicolas Duchateau, Nicholas Ayache

We propose a method based on deep learning to perform cardiac segmentation on short axis MRI image stacks iteratively from the top slice (around the base) to the bottom slice (around the apex).

Cardiac Segmentation Segmentation

3D Consistent Biventricular Myocardial Segmentation Using Deep Learning for Mesh Generation

no code implementations29 Mar 2018 Qiao Zheng, Hervé Delingette, Nicolas Duchateau, Nicholas Ayache

We present a novel automated method to segment the myocardium of both left and right ventricles in MRI volumes.
