Hyperpolarization apparatus, system and process

An apparatus (100a (i), 100a (ii), 100a iii), 100a (iv), 200) for enhancing polarization of a 13C isotope-based magnetic resonance imaging contrast agent, comprising: one or more structures of diamond material (120 (i), 120 (ii), 120 iii), 120 (iv), 210, 220), and one or more channels (105a (i), 105a (ii), 105a iii), 105a (iv), 205) disposed adjacent to the structures of diamond material (120 (i), 120 (ii), 120 iii), 120 (iv), 210, 220); a structure of diamond material (120 (i), 120 (ii), 120 iii), 120 (iv), 210, 220) provides a source of negatively charged nitrogen vacancy (NV-) centers for polarization of 13C isotope-based magnetic resonance imaging contrast agents disposed in one or more channels (105a (i), 105a (ii), 105a iii), 105a (iv), 205); and the diamond material structure (120 (i), 120 (ii), 120 iii), 120 (iv), 210, 220) provides a light guide for light for excitation of nitrogen vacancy (NV-) centers for polarization of 13C isotope based magnetic resonance imaging contrast agents. 一种用于增强基于13C同位素的磁
