Detección automática de hueso en imágenes médicas 3D a partir de segmentación con mallado anisótropo adaptativo

García Nicolás, Juan Ignacio (Universitat Politècnica de València, 2017-10-25)

[EN] In Finite Element analysis of medical images, obtained by CT Scan and magnetic resonance, there is a problem in the calculus because of the same color scale of different body parts, for example, sometimes the cancellous ...
Evaluación a priori del nivel de sujeción de implantes protésicos mediante análisis de vibraciones con simulaciones patient specific realizadas con el Cartesian grid Finite Element Method (cgFEM)

Estévez Díaz, Cristian (Universitat Politècnica de València, 2017-10-25)

[EN] The Department of Mechanical and Materials Engineering of the University Polytechnic of Valencia has developed some efficient Finite Element codes in Matlab based on the use of geometry independent Cartesian grids ...
Imposing Dirichlet boundary conditions in hierarchical Cartesian meshes by means of stabilized Lagrange multipliers

Tur Valiente, Manuel; Albelda Vitoria, José; Nadal Soriano, Enrique; Ródenas García, Juan José (Wiley, 2014-05-11)

[EN] The use of Cartesian meshes independent of the geometry has some advantages over the traditional meshes used in the finite element method. The main advantage is that their use together with an appropriate hierarchical ...
Magnetic resonance imaging gridding reconstruction methods with and without density compensation functions

Moratal Pérez, David; Vallés Lluch, Ana; Bodí, Vicent; Brummer, Marijn Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2011-03)

Reconstruction of magnetic resonance images from data not falling on a Cartesian grid is widely used for fast acquisitions, and it is a Fourier inversion problem typically solved using convolution interpolation, also known ...
Simulación de regeneración ósea mediante el Cartesian grid finite element method (cgFEM)

León Uribe, Óscar Mauricio (Universitat Politècnica de València, 2019-11-06)

[ES] El Cartesian grid finite element method (cgFEM) desarrollado en el CIIM es una metodología para la simulación númerica que permite generar, de manera muy eficiente modelos de elementos finitos a partir de ...
Stabilized method of imposing Dirichlet boundary conditions using a recovered stress field

Tur Valiente, Manuel; Albelda Vitoria, José; Marco, Onofre; Ródenas, J.J. (Elsevier, 2015-11-01)

[EN] This paper proposes a new formulation to impose Dirichlet boundary conditions on immersed boundary Cartesian Finite Element meshes. The method uses a recovered stress field calculated by Superconvergent Patch Recovery ...
Superconvergent patch recovery with constraints for three-dimensional contact problems within the Cartesian grid Finite Element Method

Navarro-Jiménez, José-Manuel; Navarro-García, Héctor; Tur Valiente, Manuel; Ródenas, Juan José (John Wiley & Sons, 2020-03-30)

[EN] The superconvergent patch recovery technique with constraints (SPR-C) consists in improving the accuracy of the recovered stresses obtained with the original SPR technique by considering known information about the ...
Vertebrae segmentation in CT Scans based on parametric CAD models for the analysis of structural behaviour by means of the Cartesian grid finite element method (CGFEM)

Benavides Serrano, Andrés Felipe (Universitat Politècnica de València, 2019-10-30)

[ES] En este Trabajo Fin de Máster, se presenta el proceso de segmentación de las vértebras lumbares en imágenes médicas (Tomografías computarizadas) mediante un modelo de CAD paramétrico y su respectivo análisis estructural ...
