Phase & Frequency Encoding
•
Need to still encode signal in remaining directions
(x & y)
Use changes of frequency & phase
•
When a gradient is applied the spins will be at
different phases once the gradient has been
turned off
•
This is the role of the phase encoding gradient
•
Used in combination with frequency encoding
gradient in the 2
nd
direction...
