Inverse-FEM Characterization of a Brain Tissue Phantom to Simulate Compression and Indentation

The realistic simulation of tool-tissue interactions is necessary for the development of surgical simulators and one of the key element for it realism is accurate bio-mechanical tissue models. In this paper, we determined the mechanical properties of soft tissue by minimizing the difference between e...

In this paper, we determined the mechanical properties of soft tissue by minimizing the difference between experimental measurements and the analytical or simulated solution of the deformation. Then, we selected the best model parameters that fit the experimental data to simulate a bonded compression and a needle indentation with a flat-tip. We show that the inverse FEM allows accurate material property estimation. We also validated our results using multiple tool-tissue interactions over the same specimen.La simulación realista de las interacciones herramienta-tejido es necesaria para el desarrollo de simuladores quirúrgicos y uno de los elementos clave para su realismo son los modelos precisos de tejido biomecánico. En este artículo, determinamos las propiedades mecánicas del tejido blando minimizando la diferencia entre las mediciones experimentales y la solución analítica o simulada de la deformación. Luego, seleccionamos los mejores parámetros del modelo que se ajustan a los datos experimentales para simular una compresión unida y una sangría de aguja con una punta plana. Mostramos que el FEM inverso permite una estimación precisa de la propiedad del material. También validamos nuestros resultados usando múltiples interacciones herramienta-tejido sobre la misma muestra.application/pdfengUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/1704http://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/1704Copyright (c) 2012 Elizabeth Mesa-Múnera, Juan F Ramírez–Salazar, Pierre Boulanger, John W BranchAcceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 8, No 16 (2012)Inverse-FEM Characterization of a Brain Tissue Phantom to Simulate Compression and IndentationCaracterización de tejido cerebral artificial utilizando Inverse-FEM para simular indentación y comprensiónarticleinfo:eu-repo/semantics/articlepublishedVersioninfo:eu-repo/semantics/publishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Inverse FemCompression TestIndentationTissue CalibrationSurgical SimulatorsFem InversaPrueba De CompresiónSangríaCalibración De TejidosSimuladores QuirúrgicosMesa-Múnera, ElizabethRamírez–Salazar, Juan FBoulanger, PierreW Branch, JohnUniversidad Nacional de ColombiaUniversidad Nacional de ColombiaUniversity of AlbertaUniversidad Nacional de ColombiaIngeniería y Ciencia8161136ing.cienc.THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/cb44a7a4-a7ab-4b49-80d9-124f5f10c9f7/downloadda9b21a5c7e00c7f1127cef8e97035e0MD51ORIGINAL1.pdf1.pdfTexto completo PDFapplication/pdf4424019https://repository.eafit.edu.co/bitstreams/66dc699f-bf15-4d97-8c78-baf7d83e8ede/downloadf8b80d2b574dc256198a3ca8f544ae8cMD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html374https://repository.eafit.edu.co/bitstreams/2bc1fafc-e442-470f-a2e7-210dd1b552f2/download6a1a0cbbca9ac5a3172a0f08edac557cMD5310784/14447oai:repository.eafit.edu.co:10784/144472020-03-02 21:49:06.333open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co
