Abstract: A process for enhancing polarization of 13C for subsequence MRI imaging, the process comprising providing a suspension consisting of a first plurality of particulates having NV centers and a second plurality of particulates for providing internal reflection of light with wavelength for the excitement of NV centers and 13C; and applying light, magnetic field and microwave to said suspension, such that the NV centers are polarized and such that the electron spins of the VN centres are transferred to 13C atoms upon the Rabi frequency of the NV centres matching the Larmor frequency of 13C; wherein the particulates of the second plurality reflect and transmit the light through the suspension such that said light is distributed through said suspension.
