DYNAMIC WAVE SETUP

A Dynamic Setup for Elementary Geometry

In this article we survey the theoretical background that is required to build a consistent and continuous setup of dynamic elementary geometry. Unlike in static elementary geometry in dynamic elementary geometry the elements of a construction are allowed to move around as long as the geometric constraints intended by the construction are not violated. A typical problem in such a scenario is to...

A Traveling-Wave Setup for Parallel RF Transmission

Introduction The traveling-wave concept for ultra high field MRI offers high FOV and patient space. In [1] a patch antenna with two ports was used to excite the two degenerate TE11 modes of a circular waveguide, which are the only modes below cut-off in an empty bore at 7T. To extend the traveling-wave concept for parallel transmit with more than two channels more degrees of freedom are needed....

Shear-Wave Dynamic Behavior using Two Different Orientations

For laterally complex media, it may be more suitable to take a different orientation of thedisplacement vector of Shear-waves. This may change the sign of several imaginary reflections andconversion coefficients to be used in reservoir characterization and AVO (Amplitude Versus Offset)analysis or modeling. In this new convention the positive direction of the displacement vector ofreflected Shea...
