A strain-based elastography is developed to identify lesions from the phase information of
ultrasonic radio frequency (RF) signals in this study: a phase shift method using prior …

Ultrasound elastography involves imaging tissue while it undergoes deformation and
inferring its mechanical properties from the deformation pattern. The initial deformation in the …

Palpation has been widely used to detect hard tumorous tissues surrounded by softer
normal tissues. The goal of ultrasound tissue elasticity imaging is to extract information …

The purpose of ultrasound elastography is to identify lesions by reconstructing the hardness
characteristics of tissue reconstructed from ultrasound data. Conventional quasi-static …

In elastography, change in signal shape from tissue deformation and nonaxial tissue motion
reduce correlation between the pre-and postcompression echo signals. Appropriate global …

Ultrasound transducers are commonly tracked in modern ultrasound navigation/guidance
systems. In this article, we demonstrate the advantages of incorporating tracking information …

Quasi-static ultrasound elastography (USE) is an imaging modality that consists of
determining a measure of deformation (ie strain) of soft tissue in response to an applied …

In this paper, a novel computationally efficient quasi-static ultrasound elastography
technique is introduced by optimizing an energy function. Unlike conventional elastography …

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 …

In ultrasound elastography, the strains in the axial direction are usually calculated by
applying gradient operator on the estimated axial displacements. Unfortunately, the direct …
