A Current Amplifier for Local Coil Pre-amplification of NMR/MRI Signals
The magnetic resonance imaging (MRI) systems are used for a variety of imaging application. The present invention discloses an improving MRI device and method by amplifying signals received by resonant NMR coils of MRI systems. It utilizes positive feedback from low-noise Field-Effect Transistor to amplify the signal current that can be coupled out...

Local Magnetization Spoiling Using a Gradient Insert for Reducing the Field of View in Magnetic Resonance Imaging
The present invention provides a method and device for eliminating alias artifacts encountered in MRI when the field of view is made smaller than the subject being imaged. Significant advantages accrue from reducing the field of view to a smaller region of interest. These include reduced imaging time, increased spatial and temporal resolution, and less...
