Abstract
Apparatuses and methods are provided for concentrating the magnetization of nuclear spins within a body, in one apparatus, a body having an electron spin moments and nuclear spin moments may subject to a polarizing magnetic field and a gradient magnetic field, such that a space-varied distribution of magnetic resonant frequencies of respective electron spin moments in the body is induced. The body may then be subject to a time-varying magnetic field configured to induce a spatial gradient of the electron spin magnetization such that concentrations of nuclear spin magnetization are induced. The body may be configured to receive a biological sample such that a concentration of nuclear spin magnetization may diffuse into the biological sample. The apparatus may further include a sensor configured to detect nuclear spin magnetization within the biological sample.
