Abstract:
A method of B1 field mapping relating to Magnetic resonance imaging (MRI) is given. In the method, RF and gradients are applied to excite and select a linear projection through a volume of interest; a radio frequency pulse sequence is transmitted to impart B1 dependent phase to the linear projection, following which a one dimensional spatial encoding signal is acquired along the linear projection; Subsequently a B1 field map based on the one dimensional spatial encoding signal is reconstructed.
