Characterization of Viscoelastic Media Combining Ultrasound and Magnetic-Force Induced Vibrations on an Embedded Soft Magnetic Sphere

Cebrecos, Alejandro; Jimenez, Noe; Tarazona Tárrega, Rafael; Company, Miguel; Benlloch Baviera, Jose María; Camarena Femenia, Francisco (Institute of Electrical and Electronics Engineers, 2021-12)

[EN] We report a method to locally assess the complex shear modulus of a viscoelastic medium. The proposed approach is based on the application of a magnetic force to a millimeter-sized steel sphere embedded in the medium ...
Comparison of the main magnetic resonance imaging acceleration strategies based on parallel imaging techniques

Acebrón Fabregat, Javier; Moratal Pérez, David; Marti Bonmati, Luis; Brummer, Marijn Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2011-03)

[EN] The main parallel imaging techniques have been implemented under MATLAB (SENSE, PILS and SPACE-RIP for image domain, and SMASH and GRAPPA for k-space domain), evaluating its characteristics about image quality and ...
