The full width at half maximum of the autocorrelation function of cancellous bone images provides a good estimate of trabecular thickness. The thickness anisotropy tensor can be calculated from k-space data acquired in MRI. Through numerical experiments on micro-CT data we show that by anisotropic sampling one can substantially improve the resolution with which the principal values of the anisotropy tensor are measured without significantly sacrificing accuracy or sensitivity.
