Fusing Echocardiography Images and Medical Records for Continuous Patient Stratification

no code implementations15 Jan 2024 Nathan Painchaud, Pierre-Yves Courand, Pierre-Marc Jodoin, Nicolas Duchateau, Olivier Bernard

Deep learning now enables automatic and robust extraction of cardiac function descriptors from echocardiographic sequences, such as ejection fraction or strain.

Ultrafast Cardiac Imaging Using Deep Learning For Speckle-Tracking Echocardiography

1 code implementation25 Jun 2023 Jingfeng Lu, Fabien Millioz, François Varray, Jonathan Porée, Jean Provost, Olivier Bernard, Damien Garcia, Denis Friboulet

The obtained results showed that, while using only three DWs as input, the CNN-based approach yielded an image quality and a motion accuracy equivalent to those obtained by compounding 31 DWs free of motion artifacts.

Phase Unwrapping of Color Doppler Echocardiography using Deep Learning

1 code implementation23 Jun 2023 Hang Jung Ling, Olivier Bernard, Nicolas Ducros, Damien Garcia

Color Doppler echocardiography is a widely used non-invasive imaging modality that provides real-time information about the intracardiac blood flow.

Extraction of volumetric indices from echocardiography: which deep learning solution for clinical use?

1 code implementation3 May 2023 Hang Jung Ling, Nathan Painchaud, Pierre-Yves Courand, Pierre-Marc Jodoin, Damien Garcia, Olivier Bernard

Deep learning-based methods have spearheaded the automatic analysis of echocardiographic images, taking advantage of the publication of multiple open access datasets annotated by experts (CAMUS being one of the largest public databases).

Echocardiography Segmentation with Enforced Temporal Consistency

1 code implementation3 Dec 2021 Nathan Painchaud, Nicolas Duchateau, Olivier Bernard, Pierre-Marc Jodoin

In this paper, we propose a framework to learn the 2D+time apical long-axis cardiac shape such that the segmented sequences can benefit from temporal and anatomical consistency constraints.

Cardiac Segmentation with Strong Anatomical Guarantees

1 code implementation15 Jun 2020 Nathan Painchaud, Youssef Skandarani, Thierry Judge, Olivier Bernard, Alain Lalande, Pierre-Marc Jodoin

In this paper, we present a framework for producing cardiac image segmentation maps that are guaranteed to respect pre-defined anatomical criteria, while remaining within the inter-expert variability.

LU-Net: a multi-task network to improve the robustness of segmentation of left ventriclular structures by deep learning in 2D echocardiography

no code implementations4 Apr 2020 Sarah Leclerc, Erik Smistad, Andreas Østvik, Frederic Cervenansky, Florian Espinosa, Torvald Espeland, Erik Andreas Rye Berg, Thomas Grenier, Carole Lartizien, Pierre-Marc Jodoin, Lasse Lovstakken, Olivier Bernard

Results obtained on a large open access dataset show that our method outperforms the current best performing deep learning solution and achieved an overall segmentation accuracy lower than the intra-observer variability for the epicardial border (i. e. on average a mean absolute error of 1. 5mm and a Hausdorff distance of 5. 1mm) with 11% of outliers.
