Abstract
An NMR system acquires data for producing an image using a spin-warp burst excitation pulse sequence. RF phase and flip-angle of each RF excitation pulse in the burst is separately controlled to maximize the SNR of the corresponding set of acquired NMR echo signals. The phase and amplitude of each acquired NMR echo signal is adjusted by an amount determined by its corresponding excitation pulse before being used for image reconstruction.
