As the three-dimensional fast spin echo (3D FSE) imaging uses greater than 100 refocusing pulses which generate several higher-order echoes, its Bloch simulation is challenging. The simulation was performed using a numerical phantom with 256 cube voxels and 320 subvoxels (isochromats) in the readout direction. The simulation was performed using approximately 1.58 billion isochromats and the calculation time was nearly 15 hours using an RTX 2080Ti graphics processing unit having 11 GB memory. The calculated result demonstrated that the 3D FSE was correctly simulated.
