Based on the Bloch equation, we can describe the working principle of the magnetic resonance imaging system with mathematic model, the inputs are the three templates of appropriate rho, T1 and T2. In this paper, the simulation process is illustrated by spin echo examples of the signal exciting, phase coding, reading-out and image reconstruction. The satisfactory results show that this method can be widely used in simulation researches.
