Analysis area's core spin selective excitation method, involves selecting orientation of layer-selective magnetic field gradients based on relative layer of analysis area at structure, such excitation area lies far away from structure

摘要

The method involves selecting an orientation of a layer-selective magnetic field gradients in interaction with an user based on a relative layer of an analysis area (59) at a structure surrounding the analysis area in such a manner that an excitation area (65) of a core spin lies far away from the surrounding structure. The resonance frequency of the excitation area is characterized by a determined chemical shift, where the analysis area is determined by an overview image.
