The authors have obtained spectral‐spatial EPR images of a phantom significantly larger than those previously obtained. Images of a homogeneous phantom 4.2 cm in diameter and 6.5 cm in length withB 1equivalent to that used for smaller samples give a similar linewidth resolution both with linewidth population distributions of width 0.1 μ T . Spatial resolution appeared to have modest degradation. Images of the large homogeneous phantom provide maps of the magnetic field of a partially shimmed magnet.
