摘要: Abstract A modified version of the echo-planar imaging technique incorporating a Carr–Purcell train 180° rf pulses (PEPI) has been implemented on standard spectrometer. It is demonstrated that artifacts in image due to cumulative errors field can be reduced by replacing each pulse composite sequence three pulses. Artifact-free 3D images at 94 μm voxel resolution are obtained within 15 min. This applied study drying process an initially water-saturated model porous medium with characteristic T * 2 order 700 μs.
