METHOD AND APPARATUS FOR SLAB SELECTION IN ULTRASHORT ECHO TIME 3-D MRI |
| 摘要 |
A method for slab selection in ultrashort echo time three-dimensional MRI includes applying an excitation signal to a target under a polarizing field; applying a unipolar slab selection gradient pulse to the target, concurrent with the excitation signal; and applying a rewinder pulse to the target for less than about 30 μs, immediately after the slab selection gradient pulse, and still under the polarizing field. |
