Comparison of rat- and human-sized solenoid receive coils and respective reconstructed images of a 22 ng Fe sample in a 2.3mm3 region at the center of the FOV. For both, the axial slice imaged is z = 0, 53 projections are acquired at gantry rotations equally spaced between 0° and 180°, and 35 points are taken along the projection axis. (a) Rodent system: receive coil (a) from Tab. 1, B1 at center = 444 μT/A, AC conducting noise = 4.46 nV. 4 cm FOV. Gradient FFL = 7 T/m×7 T/m. Drive field = 50 mT at 10 kHz. Max SNR = 807.5. (b) Human system: receive coil (c) from Tab. 1, B1 at center = 93 μT/A, AC conducting noise = 9.77 nV. 20 cm FOV. Gradient FFL = 1.5 T/m×1.5 T/m. Drive field = 25 mT at 10 kHz. Max SNR = 42.6. SNR ratio = 19.
