Let us consider once again all the steps in an MR sequence:
  1. 1. Excitation

    Switching on the slice-selection gradient, Excitation pulse (RF pulse),

    Switching off the slice selection gradient.

  2. 2. Phase encoding

    Switching on the phase-encoding gradient for a short time, but each time with a different strength.

  3. 3. Echo generation

    There are two different possibilities, which we shall discuss immediately.

  4. 4. Measurement

    Switching on the frequency encoding gradient, Receiving the echo.
