Abstract :
We consider signal processing methods for phased-array magnetic resonance imaging (MRI). A theoretical description of a phased-array MRI data model is presented and three image reconstruction algorithms are proposed to estimate the effective image pixels. An analysis is provided to show how the new algorithms compare to conventional reconstruction methods.
