Fig 9. The same slice from a 643 3D phantom acquisition at 1x1x1 mm3 spatial resolution (spin echo, TE = 19 ms, TR = 500 ms, 32x32 phase encoding steps with zero filling to get a 643 matrix data, Tacq = 8.5 min for NEX = 1) at (a) different NEX values and (b) the corresponding SNR together with the related $const*\sqrt{NEX}$ fit (dotted line).

Although a longer acquisition time is needed, images with a resolution of 1 mm³ can be recorded with the VLF-MRI system.
