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.
