Banding artefacts in images
acquired by bSSFP are a big challenge in fast MRI as they can considerably
reduce image quality and deteriorate the diagnostic value. As the steady state
tolerates small shifts in frequency, it is possible to acquire a frequency-modulated
bSSFP. Unfortunately a simple gridding reconstruction of such a measurement
suffers from signal loss. Our study proposes a multi-frequency reconstruction
and demonstrates its capability of reconstructing banding-free 3D images while
retaining the high signal levels of
standard bSSFP.
