Figure 1

Overview of the SQUID ULF MRI setup with reaction chamber/imaging phantom and SABRE hyperpolarization scheme. (a) SQUID setup including gradient coils, dewar for liquid helium, SQUID, B1, and B0 coils. To keep the schematic clear, only the x gradient of the planar gradient coils is shown. (b) 3D rendered inner volume of the star-phantom of 15 × 15 × 20 mm, true size with illustrated parahydrogen bubbles. (c) Schematic of the SABRE process that yields hyperpolarization of the [1-13C]pyruvate substrate via J-coupling interactions in appropriate alternating (AC) or constant (DC) magnetic fields.
