k-spaceA new type of graphical tool for explaining and analyzing magnetic resonance imaging pulse sequences is developed and illustrated. This tool combines the partition diagram, which shows the evolution of multiple echoes with the application of multiple RF pulses, and k-space graphs, wh...
using mri pulse sequences to generate raw data which is stored in k-space and then taking that k-space based data and using an image reconstruction algorithm to ultimately generate an image so today we're going to specifically focus on the first two steps so how we sample the raw data us...
The inset shows a schematic diagram of the position and propagation direction of the eigenstates. corresponds to the reflections at the left intersection and the second peak is caused by the reflected light at the right intersection in the directional coupler. The peaks between 0 and 0.8 ps do...
The phase diagram of the high-Tc cuprates is dominated by the Mott insulating phase of the parent compounds. As we approach it from large doping, a standar... LD Medici,G Giovannetti,M Capone - 《Physical Review Letters》 被引量: 69发表: 2012年 Non-Fermi Liquid behavior in Neutral Bilay...
or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or ...
FIG. 1 is a timing diagram showing view ordering by k-space radius, kr according to a first embodiment of the present invention as applied to lower peripheral extremities; FIG. 2 shows how the statistical parameter used to evaluate the image quality is derived from arterial data; FIG. 3...
Pulse sequence diagram of the proposed density-weighted non-water suppressed semi-LASER MRSI acquisition method. Prior to semi-LASER localization, narrow-band adiabatic RF pulses invert the spectral range where metabolite signals are expected either upfield or downfield with respect to water. A density...

Periodic structures have a large influence on propagating waves. This holds for various types of waves over a large range of length scales: from electrons in atomic crystals1 and light in photonic crystals2,3,4 to acoustic waves in sonic crystals5. The e
