Abstract:
1. A method for generating an effective equivalent of a simultaneous transmission of excitation RF signals to a targeted living tissue disposed within a moderate to high strength magnetic field for magnetic resonance imaging, said method comprising the steps of: accessing a MRI assembly able to produce electromagnetic waveforms as a RF excitation pulse stream on-demand using a plurality of independent transmission channels which are in operative communication with multiple individual transmit RF coils in a RF array for the conveyance of a RF excitation pulse stream, wherein the total number of independent transmission channels is measurably fewer than the total greater measurable number of individual transmit RF coils within said RF array; dividing the total greater measurable number of individual transmit RF coils within said RF array of said MRI assembly into a plurality of designated groupings, wherein each of said designated groupings constitutes a determinable portion of the total measurable number of individual transmit RF coils within said RF array; producing a RF excitation pulse stream within said MRI assembly for conveyance by the measurably fewer number of independent transmission channels to the measurable greater number of individual transmit RF coils in said RF array; splitting said produced RF excitation pulse stream into not less than two separate and sequentially deliverable RF pulse flows, each of which can be individually conveyed and separately delivered in sequence via the a measurable number of independent transmission channels to one of said designated groupings of individual transmit RF coils in said RF array; sequentially conveying each of said split RF pulse flows via the the measurable number of independent transmission channels to one of said designated groupings of individual transmit RF coils in said RF array for separate and concurrent transmissions of B directing separate and concurrent transmissions of B
