Abstract:

BACKGROUND: At present, magnetic resonance imaging (MRI) has been extensively clinically used due to high spatial resolution and contrast of soft tissue. However, the imaging time is very long, and it is vulnerable to the impact of patient’s body movement, resulting in motion artifact.
OBJECTIVE: To eliminate MRI motion artifact and improve image quality.
METHODS: MRI motion artifact was canceled with phase correction algorithm and level set algorithm. Image quality was enhanced after cancelling artifact with fuzzy enhancement algorithm.
RESULTS AND CONCLUSION: Results proved that the images obtained by improved phase correction algorithm are better than those by original phase correction algorithm.
