Nowadays, obtaining high-quality magnetic resonance (MR) images is a complex problem due to several acquisition factors, but is crucial in order to perform good diagnostics. The enhancement of the resolution is a typical ... -
Deep learning-based super-resolution of 3D magnetic resonance images by regularly spaced shifting
Thurnhofer-Hemsi, Karl; López-Rubio, Ezequiel; Domínguez, Enrique; Luque-Baena, Rafael Marcos; Roé-Vellvé, Núria (Elsevier, 2020-07-20)
The image acquisition process in the field of magnetic resonance imaging (MRI) does not always provide high resolution results that may be useful for a clinical analysis. Super-resolution (SR) techniques manage to increase ... -
Ecolalia mitigada y conducta de aproximación: plasticidad compensatoria en los circuitos cerebrales de lenguaje

Introducción. Las descripciones tradicionales de afasia atribuyen las alteraciones lingüísticas a daño de tejido cerebral, principalmente en el hemisferio izquierdo. Esta es una explicación lógica para aquellos síntomas ... -
Introducción a las técnicas de neuroimagen
(2019-05-06)La tomografía por emisión de positrones (PET) y la resonancia magnética (RM) ofrecen la posibilidad de estudiar la anatomía del cerebro y su plasticidad, y de detectar las zonas que se activan o las redes que tienen su ... -
Is the emergence of speech errors in chronic post-stroke aphasia a result of ongoing compensatory brain plasticity mechanisms?
López-Barroso, Diana; Torres-Prioris, María José; Roé-Vellvé, Núria; Paredes-Pacheco, Jose; Dávila-Arias, María Guadalupe; Berthier-Torres, Marcelo Luis[et al.] (2020-12-17)
Traditional descriptions of aphasia have ascribed language disturbances to tissue damage but symptoms expressed as repetitive verbal behaviors such as echolalia, perseverations and so forth, cannot emanate from fully ... -
Multiobjective optimization of deep neural networks with combinations of Lp-norm cost functions for 3D medical image super-resolution
Thurnhofer-Hemsi, Karl; López-Rubio, Ezequiel; Roé-Vellvé, Núria; Molina-Cabello, Miguel Ángel (IOS Press, 2020-05-20)
