Research of pulse sequence in invariant gradient field MRI

In this study, a new magnetic resonance (MR) fast imaging method in the invariant gradient field is presented. In the low main magnetic field (1500 Gauss), this method exhibits the advantages of high imaging speed, low requirement to the gradient amplifier and entirely open design. This article discussed the magnetic body design, radio frequency (RF) waveform, diffusion effect and a few pulse sequences of this imaging method, and the results of computer simulation are given as well.EI05398-4042
