摘要： A computer-implemented method of building a database of pulse sequences for parallel-transmission magnetic resonance imaging, comprising:
a) for each of a plurality (S0) of subjects, determining an optimal sequence for the subject;
b) for each subject, computing the values of said or of a different cost or merit function obtained by playing the optimal sequences for all the subjects;
c) aggregating the subjects into a plurality of clusters using a clustering algorithm taking said values, or functions thereof, as metrics;
d) for each cluster, determining an averaged optimal sequence for the cluster;
e) receiving, as input, a set of features characterizing an imaging subject (IS), comprising at least a morphological feature of the subject;
f) associating the subject to one pulse sequence of the database based on said set of features using the computer-implemented classifier algorithm; and
g) performing magnetic resonance imaging using said pulse sequence.
A magnetic resonance imaging apparatus for carrying out steps e) - g) of such a method.
