Geometric Deep Learning for the Assessment of Thrombosis Risk in the Left Atrial Appendage

no code implementations19 Oct 2022 Xabier Morales, Jordi Mill, Guillem Simeon, Kristine A. Juhl, Ole De Backer, Rasmus R. Paulsen, Oscar Camara

The assessment of left atrial appendage (LAA) thrombogenesis has experienced major advances with the adoption of patient-specific computational fluid dynamics (CFD) simulations.

Attri-VAE: attribute-based interpretable representations of medical images with variational autoencoders

1 code implementation20 Mar 2022 Irem Cetin, Maialen Stephens, Oscar Camara, Miguel Angel Gonzalez Ballester

In this paper, we propose a VAE approach, the Attri-VAE, that includes an attribute regularization term to associate clinical and medical imaging attributes with different regularized dimensions in the generated latent space, enabling a better-disentangled interpretation of the attributes.


Generalizing electrocardiogram delineation -- Training convolutional neural networks with synthetic data augmentation

1 code implementation25 Nov 2021 Guillermo Jimenez-Perez, Juan Acosta, Alejandro Alcaine, Oscar Camara

Obtaining per-beat information is a key task in the analysis of cardiac electrocardiograms (ECG), as many downstream diagnosis tasks are dependent on ECG-based measurements.

Joint data imputation and mechanistic modelling for simulating heart-brain interactions in incomplete datasets

no code implementations2 Oct 2020 Jaume Banus, Maxime Sermesant, Oscar Camara, Marco Lorenzi

To tackle this problem we introduce a probabilistic framework for joint cardiac data imputation and personalisation of cardiovascular mechanistic models, with application to brain studies with incomplete heart data.

ECG-DelNet: Delineation of Ambulatory Electrocardiograms with Mixed Quality Labeling Using Neural Networks

1 code implementation11 May 2020 Guillermo Jimenez-Perez, Alejandro Alcaine, Oscar Camara

We demonstrate DL can be successfully applied to low interpretative tasks by embedding ECG detection and delineation onto a segmentation framework.

A Radiomics Approach to Computer-Aided Diagnosis with Cardiac Cine-MRI

no code implementations25 Sep 2019 Irem Cetin, Gerard Sanroma, Steffen E. Petersen, Sandy Napel, Oscar Camara, Miguel-Angel Gonzalez Ballester, Karim Lekadir

In this paper, we present a new approach to identify CVDs from cine-MRI by estimating large pools of radiomic features (statistical, shape and textural features) encoding relevant changes in anatomical and image characteristics due to CVDs.

Fast quasi-conformal regional flattening of the left atrium

2 code implementations16 Nov 2018 Marta Nuñez-Garcia, Gabriel Bernardino, Francisco Alarcón, Gala Caixal, Lluís Mont, Oscar Camara, Constantine Butakoff

Two-dimensional representation of 3D anatomical structures is a simple and intuitive way for analysing patient information across populations and image modalities.


Mind the gap: quantification of incomplete ablation patterns after pulmonary vein isolation using minimum path search

1 code implementation17 Jun 2018 Marta Nuñez-Garcia, Oscar Camara, Mark D. O'Neill, Reza Razavi, Henry Chubb, Constantine Butakoff

Pulmonary vein isolation (PVI) is a common procedure for the treatment of atrial fibrillation (AF).
