method and apparatus for magnetic resonance imaging with sequential selection of modes of resonance

摘要

A method (10) for acquiring magnetic resonance data from a sample (50) to be analyzed through a fixed geometry configuration coil suitable for transmitting radiofrequency signals ‘suitable for exciting said sample and/or detecting magnetic resonance signals from the sample (50) is described. The coil (100) comprises a plurality of current elements (20,21,22) and exhibits a frequency response comprising a plurality of resonant modes (M1, M2, M3) each associable to a respective resonant frequency (f1,f2,f3) depending on electrical features of the current elements (20,21,22), the current elements (20,21,22) comprising at least one current element having electrical features that may be regulated based on a respective control signal (S_CV0, S_CV1, S_CV2). The method provides for synthesizing the control signal such as to obtain magnetic resonance data from a same sample for a given first resonant frequency of interest sequentially using resonance modes having different spatial field distributions.
