US 9,804,243 B2 · Magnetic resonance imaging apparatus

Abstract

A magnetic resonance imaging apparatus of an embodiment includes: an imaging condition setting section configured to set an imaging condition for a main scan, a preparatory scan performing section configured to repeat a preparatory scan to be performed by the use of the imaging condition for a main scan and a changeably inputted center frequency so as to generate a preparatory image in real time, a display section on which the preparatory image can be displayed in real time, an optimum center frequency setting section configured to change the center frequency so as to change a situation in which a banding artifact appears and configured to set an optimum center frequency according to a user operation based on an observation of the preparatory image, and a main scan performing section configured to reconstruct an image for a diagnosis by using the optimum center frequency having been set.

Dependent claims

A magnetic resonance imaging (MRI) apparatus comprising:

an MRI system including at least one processor configured to
set an imaging condition for a main scan to obtain a diagnostic image;
accept a user input center frequency changeably inputted in real time;
repeat a preparatory scan performed by use of the set imaging condition and the center frequency changeably inputted in real time and generate preparatory images in real time visibly depicting a banding artifact using the preparatory scan data acquired in the repeated preparatory scans;
display the preparatory images in real time;
change the center frequency according to a user operation via a user interface so as to change where the banding artifact appears, the optimum center frequency being set according to a user operation based on observation of the preparatory images;
and
perform the main scan by using the set optimum center frequency and the set imaging condition for the main scan to reconstruct the diagnostic image.
