Abstract: A method and apparatus for Magnetic Resonance Imaging with specialized imaging coils possessing high Signal-to-Noise-Ratio (SNR). Imaging and/or Radio Frequency receiving coils include a ballistic electrical conductor such as carbon nanotubes, the ballistic electrical conductor having a resistance that does not increase significantly with length. Due to their enhanced SNR properties, system designs with smaller static magnetic field strength can be constructed for the same quality of imaging, leading to substantial reductions in system size and cost, as well as to enhanced imaging with existing MRI systems.

Abstract: A method and apparatus are disclosed for Magnetic Resonance Imaging using specialized signal acquisition and processing techniques for image reconstruction with a generally inhomogeneous static magnetic field. New signal processing methods for image reconstruction and for minimizing dephasing effects are disclosed. Imaging systems with smaller static magnetic field strengths and smaller hardware demands than those with homogeneous static magnetic fields are provided, leading to significant reductions in system size and cost as compared to standard MRI systems. Such systems can also exploit imaging coils having high Signal-to-Noise-Ratio (SNR), including those made from Carbon nanotube conductors, leading to further imaging system efficiencies.

Abstract: An apparatus is disclosed for Magnetic Resonance Imaging with specialized imaging coils possessing high Signal-to-Noise-Ratios (SNR). Radio Frequency transmitting and/or Radio Frequency receiving elements include carbon nanotube material, a ballistic electrical conductor having a resistance that does not increase significantly with length. The shapes of the receiving and transmitting elements can be linear, curvilinear, or coiled. The carbon nanotube material can be layered. Due to their enhanced SNR properties, preferred embodiments have smaller static magnetic field strengths with imaging quality comparable to known field systems, leading to substantial reductions in system size and cost. Other preferred embodiments provide enhanced imaging with known MRI static magnetic field strengths.
