George A Brock Fisher, Mckee D Poland, Patrick G Rafter: Means for increasing sensitivity in non-linear ultrasound imaging systems. Hewlett Packard Company, Pamela Lau Kee, November 26, 1996: US05577505 (97 worldwide citation)

An image with increased sensitivity to non-linear responses, particularly second harmonic responses, can be achieved by measuring the ultrasound response under multiple excitation levels. The responses gathered from the multiple excitation levels are gain corrected in an amount corresponding to the ...
