Multisection fat-water imaging with chemical shift selective presaturation.
Proton chemical shift imaging yielding separate water and lipid images was performed in a multisection mode on a clinical 1.5-T whole-body magnetic resonance imaging unit. Imaging was performed with a minor modification of the standard multisection spin-warp technique: that is, the addition of a sinc pulse or a soft square pulse and a homospoil gradient at the beginning of the pulse sequence. P...
متن کاملA subspace method for frequency selective identification of stochastic systems ⋆
A parametric method for the estimation of vector valued discrete-time stochastic systems or equivalently the spectrum of a stochastic process is presented. The key feature is that the method can be used to frequency selectively fit the model to the data. This means that parts of the spectrum can be modeled with a lower model order than otherwise would be necessary if the entire spectrum would b...
متن کاملAn Intelligent Non-Trial-and-Error Design Method for Double Screen Frequency Selective Surfaces
An intelligent design method of double screen frequency selective surfaces (FSSs) is addressed in this paper. The employed unit cell is composed of two metallic screens, which are printed on both sides of a substrate. The presented non-trial-and-error approach is investigated based on the separate design of each screen. With the help of some physical intuition and an equivalent circuit model, i...
