| Abstract: | Based on the interpretation of the pulse sequence program, we have built a computer simulation software. The software is suitable for any pulse sequence in MRI, It consistS of severval parts f the physical model of MRI sample, the simulation of the MRI process, rearrangement of the FID signals, and fourier transformations or imageback projection reconstruction. We describe shortly the behaviour of spin system inMRI process and the idea of the software designing. We selected two famous MRI methods: GE and SEPI as examples to introduce the use of this simulation software. |
