The Palpation imaging (PI) that closely mimics manual palpation but with enhanced sensitivity and specificity might be considered as a branch of elasticity imaging or elastography. The PI probe with a force sensor array mounted on its tip acts similarly to human fingers during clinical examination. PI translates the tissue’s elastic properties into a digital map and provides quantitative characterization of the detected mass using the data obtained by the sensor array pressed against the examined site. The changes in the surface stress patterns as a function of displacement, applied load and time provide information about the elastic composition and geometry of the underlying tissue structures. The objective of this study is the clinical evaluation of palpation imaging (PI) for breast lesion diagnosis.
