In ultrasound elastography, the resolution and accuracy of strain estimation are bounded by
the sampling period when the echo signal is digitized. Here, the authors describe three new …

The range of strains that can be imaged by any practical elastographic imaging system is
inherently limited, and a performance measure is valuable to evaluate these systems from …

Tissue deformation in ultrasound imaging is an inevitable phenomenon and poses
challenges to the development of many techniques related to ultrasound image registration …

Background The convectional strain-based algorithm has been widely utilized in clinical
