1. A magnetic resonance simulation apparatus, comprising:
an input interface configured to input:
a subsequence of a magnetic resonance pulse sequence, the subsequence being a subject of a simulation of a magnetic resonance phenomenon, and
a plurality of isochromats having a same B0 shift at different positions corresponding to subvoxels which are segments of each of voxels related to the simulation of the magnetic resonance phenomenon;
central processing circuitry configured to determine, based on the subsequence, two or more isochromats exhibiting equivalent magnetic resonance phenomenal behaviors as equivalent isochromats, from the plurality of isochromats; and
numerical processing circuitry configured to collectively simulate the magnetic resonance phenomenal behaviors of the equivalent isochromats due to the subsequence by a same computation.
