T₂ Mapping

Exercise 2-1

RF phase and spin echoes

The ±x and ±y RF phases, spin echoes with perfect and imperfect pulses, and single-point T₂ and T₂^*.

Exercise 2-2

Optional

Stimulated echoes

Three pulses, what an imperfect 180° does, and how echoes mix in a train.

Exercise 2-3

Measuring T₂ with an echo train

The echo train game, B₁ errors, the CPMG condition, and which echoes to fit.

Exercise 2-4

Myelin water

A T₂ distribution in every pixel of a brain slice.

Changing slides: move the mouse to the far left or right edge of the window until a grey bar appears, then click it to go back or forward. Space and Page Down also move forward. On the game slides, the arrow keys play the game instead of changing slides.
