Abstract:
Objective:To implement rapid acquisition gradient echo(RAGE)pulse sequence in clinical MRI scaner.Methods:Pascal language is engaged to edit source code.Number of slice excited,order of phase encoded,phase recycle of RF pulse,NEX,on/off of the gradients,and so on are all controlled by sequence parameters.SI×N_(phase)×N_(slice) data of 32 bctys were allocated to restore the k space.Source code of sequence was compiled with executable file and is loaded to RINMR software.Image of human brain are acquired.The experiment has been conducted on 0.36T permanent MRI system.Resuits:In the case of 256×256 matrix acquisition,time of single slice is 4 seconds.The resolution and SNR of the image are all adquately satisfy the clinical application.
