Resolution of axial shear strain elastography.
The technique of mapping the local axial component of the shear strain due to quasi-static axial compression is defined as axial shear strain elastography. In this paper, the spatial resolution of axial shear strain elastography is investigated through simulations, using an elastically stiff cylindrical lesion embedded in a homogeneously softer background. Resolution was defined as the smallest...

Statistical Analysis of a Three-dimensional Axial Strain and Axial-shear Strain Elastography Algorithm. (August 2011) Mohan Li, B.S., University of Science and Technology of China Chair of Advisory Committee: Dr. Raffaella Righetti Pathological phenomena often change the mechanical properties of the tissue. Therefore, estimation of tissue mechanical properties can be of clinical importance. Ult...
متن کاملIn vivo classification of breast masses using features derived from axial-strain and axial-shear images.
Breast cancer is currently the second leading cause of cancer deaths in women. Early detection and accurate classification of suspicious masses as benign or malignant is important for arriving at an appropriate treatment plan. In this article, we present classification results for features extracted from ultrasound-based, axial-strain and axial-shear images of breast masses. The breast-mass sti...
متن کاملShear-wave elastography for breast masses: local shear wave speed (m/sec) versus Young modulus (kPa)
PURPOSE To evaluate and compare the performance of shear-wave elastography (SWE) for breast masses using the local shear wave speed (m/sec) vs. Young modulus (kPa). METHODS A total of 130 breast lesions in 123 women who underwent SWE before ultrasound- guided core needle biopsy or surgical excision were included. With the region-of-interest placed over the stiffest areas of the lesion on SWE,...
متن کاملCartilage Nominal Strain Correlates with Gag Content and Shear Modulus in Meniscectomized Joints
* **Song, Y, **Greve, J, **Gold, GE, * **Carter, DR, * **Giori, NJ * Bone and Joint Center, VA Palo Alto Health Care System, Palo Alto, CA [email protected] INTRODUCTION Meniscectomy leads to osteoarthritis (OA) in both human and animal knee joints. Spatial changes in biochemical composition and biomechanical properties over the entire surface of articular cartilage following meniscectomy h...
