Absolute SNR (ml-1Hz1/2) computed by EM MoM (square points) at ρ=1cm from the junction of antennae made with λc/4 cable portions tuned at 0.5, 1, 1.5, 2, 3, 4, 4.7, 5 and 7T in 0.35% saline. Experimental values measured previously (20) at 1.5, 3 and 4.7 as well as our current 7T measurements are overlaid (solid circles). The data are fit to a quadratic curve (dotted line). Experimental data are corrected for system NF but include cable losses.
