A three-dimensional Fourier transform method and a multislice two-dimensional Fourier transform method were used to obtain three-dimensional proton density images of an ear of corn. Two-dimensional, transient moisture profiles were obtained from the three-dimensional images. The moisture transfer and shrinkage of the sample were analyzed from the profiles. Mass transfer occurred in the x and z directions in individual kernels, but the mass transfer between kernels was negligible.
