PMID: 26158120
J Med Imaging (Bellingham). 2015 Jul;2(3):036001. doi: 10.1117/1.JMI.2.3.036001. Epub 2015 Jul 02.

Cancer progression has been linked to mechanics. Therefore, there has been recent interest in developing noninvasive imaging tools for cancer assessment that are sensitive to changes in tissue mechanical properties. We have developed one such method, modality independent elastography...
