“SSE”: single spin-echo; “DSE”: double spin-echo; “AX”: axial; “SAG”: sagittal; “L/d”: gantry bore length (m) / bore diameter (m)
same system with two gradient settings (labeled “W”hole and “Z”oom).
image acquisition plane (AX/SAG) for specific phantom alignment direction in the magnet (RL/SI);
apparent AP elevation of the phantom at RL offset 0 mm and 120 mm;
