  • Nunes, Cecília; De Craene, Mathieu; Langet, Hélène; Camara, Oscar; Jonsson, Anders, 1973- (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Decision trees (DTs) are a widely used prediction tool, owing to their interpretability. Standard learning methods follow a locally-optimal approach that trades off prediction performance for computational efficiency. Such ...
  • Nogueira, Mariana; De Craene, Mathieu; Sanchez Martinez, Sergio; Chowdhury, Devyani; Bijnens, Bart; Piella Fenoy, Gemma (Elsevier, 2020)
    Alternative stress echocardiography protocols such as handgrip exercise are potentially more favorable towards large-scale screening scenarios than those currently adopted in clinical practice. However, these are still ...
  • Lluch Alvarez, Èric; De Craene, Mathieu; Bijnens, Bart; Sermesant, Maxime; Noailly, Jérôme; Camara, Oscar; Morales, Hernán G. (Springer, 2019)
    Cardiac modeling has recently emerged as a promising tool to study pathophysiology mechanisms and to predict treatment outcomes for personalized clinical decision support. Nevertheless, achieving convergence under large ...

    Image registration has been proposed as an automatic method for recovering cardiac displacement fields from Tagged Magnetic Resonance Imaging (tMRI) sequences. Initially performed as a set of pairwise registrations, these ...
  • Piella Fenoy, Gemma; De Craene, Mathieu; Bijnens, Bart; Tobón Gómez, Catalina, 1981-; Huguet, Marina; Avegliano, Gustavo P.; Frangi Caregnato, Alejandro (Elsevier, 2010)
    Introducción y objetivos. Se ha señalado que, en la miocardiopatía hipertrófica (MCH), la desorganización de las fibras regionales da lugar a segmentos en los que la deformación es nula o está gravemente reducida, y que ...

    Many cardiac diseases are associated with changes in ventricular shape. However, in daily practice, the heart is mostly assessed by 2D echocardiography only. While 3D techniques are available, they are rarely used. In this ...

    We propose a technique for myocardial motion estimation based on image registration using both B-mode echocardiographic images and tissue Doppler sequences acquired interleaved. The velocity field is modeled continuously ...
  • Zhang, Chong; Villa-Uriol, Maria-Cruz; De Craene, Mathieu; Pozo Soler, José Ma. (José María); Frangi Caregnato, Alejandro (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    This paper presents a technique to estimate and model patient-specific pulsatility of cerebral aneurysms over one/ncardiac cycle, using 3D rotational X-ray angiography (3DRA) acquisitions. Aneurysm pulsation is modeled as ...
  • Lluch Alvarez, Èric; Doste, Rubén; Giffard-Roisin, Sophie; This, Alexandre; Sermesant, Maxime; Camara, Oscar; De Craene, Mathieu; Morales, Hernán G. (Springer, 2017)
    Finite element methods (FEM) are generally used in cardiac 3D-electromechanical modeling. For FEM modeling, a step of a suitable mesh construction is required, which is non-trivial and time-consuming for complex geometries. ...
