1. A method that simulates magnetic resonance imaging signals, comprising: simulating an object to be scanned as a two-dimensional or a three-dimensional lattice array using a lattice array unit, with each point in the lattice array comprising: a plurality of magnetic resonance sensitive particles; simulating a statistic property of each point in the lattice array by a setting unit; and calculating raw data of a simulated magnetic resonance image without using a real magnetic resonance imaging scanner in order to perform a plurality of simulated magnetic resonance imaging sequence scans, wherein the raw data is calculated, with a calculating unit, based only on the simulated statistic property of each point in the lattice array and the performed plurality of simulated magnetic resonance imaging sequence scans applied by said calculating unit, wherein the statistic property of each point in the lattice array is simulated by setting a longitudinal relaxation time and a transverse relaxation time of each point in the lattice array.
