Anti-aliasing magnetic resonance device which reduces aliasing from regions outside of the excitation volume

摘要

In magnetic resonance apparatus, particularly magnetic resonance imaging apparatus, it is found that magnetic resonance signals generated in an alias region (D) will be aliased into the signals received by the primary receive coil (4) from the desired signal region (A-B). An additional receive coil 5 is provided to receive the signals from the alias region, and processing means (6) reduces the effect of these alias signals on the resulting desired data.
