-weighted images of a PVA cryogel sample mounted in the water tank, with the US imaging transducer mounted above it. The phase encoding direction was from top to bottom in these images, and parallel imaging was used, with signals combined using adaptive weighting. Images were taken without (a and b) and with (c and d) aluminium foil shielding of the US probe and cable, whilst the US scanner was frozen (a and c), and during B-mode imaging (b and d). The blue circle marked within the cryogel in (a) represents the circular ROI used for SNR calculations. Each image shows a field of view (FOV) measuring  cm.
