Bloch Simulator

Magnetization in the rotating frame, integrated from the Bloch equations.

Experiment Flip angle RF phase Pulse shape Pulse duration Delay / τ / TI Center off-resonance Isochromat spread (±) T1 T2

Positive off-resonance precesses clockwise seen from +z. A spread of 0 shows a single spin; otherwise the signal averages 113 spins across the range and 15 of them are drawn. The yellow arrow is the mean magnetization.
