Pathological phenomena often change the mechanical properties of the tissue. Therefore,
estimation of tissue mechanical properties can be of clinical importance. Ultrasound …

A new strain estimator for quasi-static elastography is presented, based on tracking of the
analytical signal phase as a function of the external force. Two implementations are …

In freehand elastography, quasi-static tissue compression is applied through the ultrasound
probe, and the corresponding axial strain is estimated by calculating the time shift between …

Portable wireless ultrasound has been emerging as a new ultrasound device due to its
unique advantages including small size, lightweight, wireless connectivity and affordability …

This research project examines the applicability of novel spectral domain strain estimation
algorithms to improve the clinical value of tissue elasticity images. Pathological changes can …

Tracking the displacement between the pre-and post-deformed radio-frequency (RF) frames
is a pivotal step of ultrasound elastography, which depicts tissue mechanical properties to …

In this paper, a phase-based direct average strain estimation method is developed. A
mathematical model is presented to calculate axial strain directly from the phase of the zero …

In this paper, we present a new approach to calculate 2D strain through the registration of
the pre-and post-compression (deformation) B-mode image sequences based on an …

Ultrasound strain imaging is becoming increasingly popular as a way to measure stiffness
variation in soft tissue. Almost all techniques involve the estimation of a field of relative …

Ultrasound elastography is the method of obtaining relative stiffness information of biological
tissue, which plays an important role in early diagnosis. Generally, a gradient-based strain …
