Freehand Elasticity Imaging Using Speckle Decorrelation Rate

Malignant tumours are often relatively stiff and immobile. These properties permit tumours such as breast cancers to be detected by palpation and have provided motivation for the development of new methods for imaging tissue elasticity, by ultrasonically estimating the displacement or strain distribution due to an externally applied stress. Various authors have now shown that such elasticity images may possess excellent spatial and contrast resolution1,2,3.
