1. A system comprising:
a body mold for a magnetic resonance imaging system, comprising a plurality of substrates, wherein the plurality of substrates are sequentially arranged to form a multi-layer structure in a three-dimensional space; each substrate is provided with a plurality of first accommodation bodies that accommodate first resonant objects and a plurality of second accommodation bodies that accommodate second resonant objects, the plurality of first accommodation bodies and the plurality of second accommodation bodies are arranged at intervals, the first resonant objects and the second resonant objects are alternately arranged relative to each other in both a longitudinal direction and a transverse direction that is transverse to the longitudinal direction, and the first resonant objects and the second resonant objects have different longitudinal relaxation times T1, wherein when excited by a radio frequency, the first resonant objects and the second resonant objects generate detectable magnetic resonance signals; and
wherein the plurality of substrates are sequentially arranged at specific angles to form the multi-layer structure having a fan-shaped cross-section.
