Imaging The Magnetic Resonance Signal

MRI visualization of structural anatomy requires measuring the MRI signal amplitude generated by each volume element within the tissue being imaged. Accomplishing this is more complicated than might be imagined. Because MRI does not use radio waves, it is not possible to focus "beams" of radio waves at suitable resolution to excite the MRI signal of only one volume element at a time and then sequentially sample all volume elements with this focused beam. Moreover, the sequential detection of the MRI signal from each volume element is highly inefficient and impractical.
