NMR tomography method with 2D spatial encoding using two multipole gradient fields

摘要

The method involves producing a spatially and temporally variable magnetic field by a gradient system for two-dimensional local encoding of nuclear magnetic resonance (NMR) measuring signals within an illustrated range of a measuring probe. The magnetic field, during an individual measuring cycle from stimulation to readout of the NMR measuring signal in two similar occurrences, is used within the illustrated range of the measuring probe. The latter occurrence is twisted inversely to the former occurrence around an angle. An independent claim is included for a nuclear magnetic resonance tomography device.
