Reconstructive ultrasound elasticity imaging for renal pathology detection

The real-time capability of ultrasound is it's major advantage for reconstructive elasticity imaging. In addition to providing important immediate feedback during patient examination, real-time data capture provides an excellent means for retrospective data processing. With retrospective processing, normal axial strain images can be optimized for highest SNR, the accuracy of lateral displacement estimates can be improved, and finally, non-linear elastic properties of tissue can be evaluated resulting in contrast enhancement of elasticity imaging. Retrospective processing requires no new data capture and adds new important features to reconstructive ultrasound elasticity imaging.
