Magnetic resonance simulation apparatus, magnetic resonance simulation method, and magnetic resonance imaging apparatus

A magnetic resonance simulation method comprising:

• obtaining phantom information and group information, the phantom information representing a phantom having an ensemble of positions and physical values relative to a plurality of isochromats, the group information representing groups of isochromats classified with respect to the phantom information, the isochromats that exhibit a same physical magnetization property under a condition preset according to a pulse sequence;
• collectively performing a magnetic resonance simulation with respect to isochromats classified as a same group among the plurality of isochromats, based on the group information and the phantom information;
• and
• outputting a simulation result obtained from the magnetic resonance simulation.
