Phase-Constrained Reconstruction of Sensitivity-Encoded MRI Data with POCSENSE

A. Samsonov, E. Kholmovski, C. Johnson Scientific Computing and Imaging Institute, University of Utah, Salt Lake City, Utah, United States, UCAIR, Department of Radiology, University of Utah, Salt Lake City, Utah, United States Introduction: Using phase constraints in sensitivity-encoded data reconstruction promises a number of benefits, including improved image quality, signal-to-noise ratio (...

Parallel Imaging with RASER using Multiband Frequency-modulated Excitation Pulses

Introduction: The recently described RASER sequence is a conceptual novelty in MR imaging [1]. Based on frequency-swept excitation, and timeencoding, RASER is a rapid, pure T2-weighted scheme without signal voids, ghosting and distortion artifacts present in conventional echo-planar imaging (EPI). These properties render it attractive for functional imaging (fMRI). However, in the previous impl...

Multiband plasmonic absorber based on transverse phase resonances.

We demonstrate a multiband plasmonic absorber based on transverse phase resonances. We show that the modification of conventional metallic surfaces of T-shape grooves can cause mode splitting of the plasmonic waveguide cavity modes due to lattice scattering and all the new resonant modes exhibit large absorbtivity greater than 90%. Some of the generated absorption peaks have wide-angle characte...
