The basic principles of using sonographic techniques for imaging the elastic properties of
tissues are described, with particular emphasis on elastography. After some preliminaries …

Elastography is a method that can ultimately generate several new kinds of images, called
elastograms. As such, all the properties of elastograms are different from the familiar …

Elastography is a new imaging modality where elastic tissue parameters related to the
structural organization of normal and pathological tissues are imaged. Basic principles …

The mechanical attributes of soft tissues depend on their molecular building blocks (fat,
collagen etc.), on the microscopic and macroscopic structural organization of these blocks …

Radiofrequency (RF) ablation is an interstitial focal ablative therapy that can be used in a
percutaneous fashion and permits in situ destruction of hepatic tumors. However, local tumor …

We present a concise summary of some of the fundamentals and of our work in the field of
elastography over the past 12 years. This summary is not exhaustive, since several recent …

Spectral estimation of tissue strain has been performed previously by using the centroid shift
of the power spectrum or by estimating the variation in the mean scatterer spacing in the …

We estimate the quality factor (Q) from seismic reflections by using a tomographic inversion
algorithm based on the frequency‐shift method. The algorithm is verified with a synthetic …

We report a summary of recent developments and current status of our team's efforts to
image and quantify in vivo nonlinear strain and tissue mechanical properties. Our work is …

To date, established ultrasonic methods for myocardial regional deformation recovery are
based on the Doppler effect, which has inherent limitations restricting its accuracy and use …
