Abstract

An MRI scanning method and apparatus provide increased efficiency by oversampling in the phase encoding direction. The oversampling is performed during one or more time periods (112) during the scanning sequence that would normally be unused. The addition phase encoding steps (132, 134) can be used to enhance overall image resolution. In preferred embodiments, additional phase encoding steps reduce or eliminate N/2 ghost artifacts with no increase in imaging time. Image throughput is improved by obviating the need for ghost removal post-processing of the image data.
