This contribution will present an objective and accurate approach to measuring the size, shape and orientation of discrete features within a CT volume that are small with respect to the data resolution, as defined by its point-spread function.  The method requires knowledge of the end-member CT number of the phase(s) measured, and challenges of the first-principles calculation will be explored.
