Abstract

A novel, fast, and quiet method of magnetic resonance imaging (MRI), called SWIFT (sweep imaging with Fourier transformation) has recently been introduced. In addition to SWIFT'S potential for in-vivo MRI, it creates new opportunities for MRI of materials. SWIFT currently operates in 3d radial acquisition mode. A series of segmented hyperbolic secant excitation pulses is accompanied by acquisition in the gaps. After correlation with the pulse, each excitation results in a free induction decay (FID). The spectrum corresponding to the FID is a projection. There is very little "dead time" between excitation and acquisition, making SWIFT useful for imaging of short T2 materials, but in total imaging times comparable to fast gradient echo sequences. We anticipate great interest in this new MRI sequence in the materials MRI community and look forward to exploring SWIFT'S advantages and potential relative to existing short T2 imaging techniques.
