METHOD AND APPARATUS FOR ELASTICITY IMAGING

摘要

A computational efficient algorithm (12) for compression analysis of free-hand static elasticity imaging performed using medial diagnostic ultrasound imaging equipment (14) offers tissue compression quality and quantity feedback to the operator. The algorithm (12) includes a criterion for automatic selection of the most advantageous pre- and post-compression frame pairs delivering elasticity images of optimal dynamic ranges (DR) and signal-to -noise ratios (SNR). The use of the algorithm (12) in real time eases operator training and reduces significantly the amount of artifact in the elasticity images while lowering the computational burden.
