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.

Polarization

A magnetic field induces spin polarization and a net magnetization

Detection

An RF tips the magnetization with energy absorption. During magnetization decay a signal (FID) is emitted.

Magnetic resonance image formation (encoding)

From the NMR signal to image formation

 

Spatial encoding, k-space, Sampling schemes

Design of RF pulses for detection

Inducing a Steady State Magnetization providing a continuously emitted signal from the subject

Polarization enhancement
