[Progress of studies for reduction of ghost artifact in magnetic resonance imaging].
The popularity of magnetic resonance imaging over other imaging disciplines depends predominantly on its high spatial resolution, soft tissue contrast, no hard fake trace and no radiation injury. However, the ghost artifacts produced during a magnetic resonance imaging would degrade the image badly and affect the precise orientation to focus. This paper introduced the process of studies for reduction of ghost artifact resulting from EPI imaging theory and motion of subject. A lot of researches indicated that how to reduce the ghost effectively is still a challenging task. Researchers should persist in seeking for new method to solve the difficult problem.
