Title: Pulse sequence device for MRI unit
Inventor: HEID OLIVER
IPC: G01R33/561
Filed: 1998-12-28
Granted: 2000-10-26
Abstract: After an actual measurement, a decay-high frequency pulse (RFa or RFa) is irradiated. The decay HF pulse is arranged in a time (Tr/2) after the last high frequency excitation pulse with full flip angle. The decay HF pulse has half flip angle (alpha /2) of the flip angle of the HF excitation pulse of the FISP sequence.  To fulfil the condition of a time offset of Tr/2 after the last HF excitation pulse, two decay HF pulses are added after the last used echo (S3). The distance between the last HF excitation pulse and the first decay pulse is the same as Tr and the distance between the decay pulses is Tr/2.
