Abstract
In the steady-state free precession sequence a regular sequence of phase-coherent radio-frequency pulses is applied with a repetition time shorter than the NMR relaxation times of the sample under investigation. The intensity of the resulting NMR signal has a complicated dependence on sequence repetition time and RF pulse angle, as well as dependence on the relaxation times. The purpose of this paper is to present a simple mathematical description of the SSFP NMR signals which may be used to accurately model SSFP experiments. Experimental verification of the model has been carried out on a 40 cm bore 2.35 T Bruker Medspec system.
