The modeling of induced current density in eyes from static magnetic fields produce by MR scanner
Introduction: Staff and patient Movement in static magnetic field MRI scanner induces current density in the human tissues, so cause biologic effects in people. The aim of this study was the Modelling of current density induced by moving individual with different velocities in static magnetic field of magnetic resonance imaging. Materials and Methods: current ...
متن کاملDensity-Weighted Nyström Method for Computing Large Kernel Eigensystems
The Nyström method is a well-known sampling-based technique for approximating the eigensystem of large kernel matrices. However, the chosen samples in the Nyström method are all assumed to be of equal importance, which deviates from the integral equation that defines the kernel eigenfunctions. Motivated by this observation, we extend the Nyström method to a more general, density-weighted versio...
متن کاملA Bayesian approach for image denoising in MRI
Magnetic Resonance Imaging (MRI) is a notable medical imaging technique that is based on Nuclear Magnetic Resonance (NMR). MRI is a safe imaging method with high contrast between soft tissues, which made it the most popular imaging technique in clinical applications. MR Imagechr('39')s visual quality plays a vital role in medical diagnostics that can be severely corrupted by existing noise duri...
متن کاملEffect of Current Density, Temperature, and Contact Paste on Flash Sintered 8YSZ
Flash sintering has been investigated as a modern sintering method through examining the effect of processing parameters such as current density, temperature, and contact paste on the flash sintered 8YSZ characteristic. 95% of theoretical density was achieved at 800°С in 30sec with a field intensity of 100V.cm-1 and a current density of 160mA.mm-2. Such relative density in conventional sinterin...
متن کاملImplementation of the Equilateral Triangle in the Multiple Correlation Function Approach as Model Geometry for Restricted Diffusion
Introduction Magnetic resonance diffusion weighted imaging finds widespread application, e.g. in medical imaging or porous media research [1] since the measured diffusion is linked to the confining geometry. Although this link is not trivial, efficient techniques like the multiple correlation function (MCF) approach exist [2], that rely on the Laplace eigensystem, and allow for a more efficient...
