Cardiac MRI Segmentation with Strong Anatomical Guarantees

Published in Medical Image Computing and Computer Assisted Intervention (MICCAI), 2019

In this paper, we propose a cardiac MRI segmentation method which always produces anatomically plausible results.

On the effectiveness of GAN generated cardiac MRIs for segmentation

Published in Medical Imaging with Deep Learning (MIDL), 2020

In this work, we propose a Variational Autoencoder (VAE) - Generative Adversarial Networks (GAN) model that can produce highly realistic MRI together with its pixel accurate groundtruth for the application of cine-MR image cardiac segmentation.

Cardiac Segmentation with Strong Anatomical Guarantees

Published in IEEE Transactions on Medical Imaging (IEEE TMI), 2020

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.

Echocardiography Segmentation With Enforced Temporal Consistency

Published in IEEE Transactions on Medical Imaging (IEEE TMI), 2022

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.

Neural Teleportation

Published in Mathematics, 2023

We explore a process called neural teleportation, a mathematical consequence of applying quiver representation theory to neural networks.

Extraction of Volumetric Indices from Echocardiography: Which Deep Learning Solution for Clinical Use?

Published in Functional Imaging and Modeling of the Heart (FIMH), 2023

We propose a comprehensive comparison between the current best performing methods in medical/echocardiographic image segmentation, with a particular focus on temporal consistency and cross-dataset aspects.
