Magnetic Resonance - Magnetic Resonance Imaging (MRI)
Magnetic Resonance: A magnetic field splits spin energetic levels and induces spin precession. Energy transitions under conditions of Magnetic Resonance.
MRI: Polarization
A magnetic field induces spin polarization and a net magnetization
MRI: Detection
An RF tips the magnetization with energy absorption. During magnetization decay a signal (FID) is emitted.
MRI: Polarization enhancement techniques
MRI: Detection RF pulse design
Inducing a Steady State Magnetization providing a continuously emitted signal from the subject
