摘要：
A 3D volumetric elasticity reconstruction method is proposed for prostate elastography. The method uses crosscorrelation based I/Q data tracking technique in 2D with I-Beam transducer to reconstruct 3D volumetric elastograms. The elevational motion is tracked using block matching based on minimum of the sum-of-absolute differences between the successive elevational frames. 3D elasticity reconstruction estimates the 3D shape and size of cancers, which may be an important step towards their classification as a malignant or a benign.
