This paper introduces the spectral crosscorrelation (SCC) function for characterizing tissue scattering structures with ultrasonic back-scattered signals. Analytical, simulation, and experimental results (liver tissue scans containing metastases) are presented to indicate the potential of utilizing phase information through the SCC function in order to detect disruptions in the scatterer distributions due to invading cancer cells. Simulation and analytical results demonstrate that SCC functions reveal the average periodic spacings between tissue scatterers better than the power spectral density (PSD) in cases when less regular inter-scatterer spacings exist.
