Abstract
An apparatus and method of experimentation for measuring frequency-dependent angle scattering from in vitro tissue samples and tissue-like scattering media have been developed. Distinguishing features of this method are that data collection is rapid, data reduction is simple, and results, given in the form of the differential scattering cross section per unit volume, are accurate and absolute. Reported are the results of tests to determine the overall accuracy of the method. Also, results of the differential scattering cross section per unit volume from female human breast tissue are presented.
