Motivated by the need for reliable and uniform water fat
separation, which is used to improve medical diagnosis,
we present a novel technique for water fat
decomposition. This technique combines the advantages of
balanced steady-state free precession (bSSFP) MRI with
Dixon reconstruction to produce water fat decomposition
with high SNR in a short imaging time, while
simultaneously reducing banding artifacts that
traditionally degrade image quality. This algorithm
utilizes four phase-cycled bSSFP acquisitions at
specific echo times to generate in-phase and
out-of-phase images. Linear combinations of the
strongest signals from these images are used to produce
separate water and fat images.
