	abstract = {<p>The clinical feasibility of 2D elastography methods is hindered by the requirement that the operator avoid out-of-plane motion of the ultrasound image during palpation, and also by the lack of volumetric elastography measurements In this paper, we develop, evaluate a 3D elastography method operating on volumetric data acquired from a 3D probe Our method is based on minimizing a cost function using dynamic programming (DP) The cost function incorporates similarity of echo amplitudes, displacement continuity We present, to the best of our knowledge, the first in-vivo patient studies of monitoring liver ablation with freehand DP elastography The thermal lesion was not discernable in the B-mode image but it was clearly visible in the strain image as well as in validation CT We also present 3D strain images from thermal lesions in ex-vivo ablation Good agreement was observed between strain images, CT, gross pathology</p>

	abstract = {<p>In Total Hip Replacement (THR) procedures, misalignment of the acetabular component can lead to dislocation, impingement For the successful alignment of acetabular component, precise estimation of pelvic anatomical coordinate system is necessary Conventional navigation systems use CT scan or fluoroscopy, or involve implanted bone fiducials or invasive probing of bony landmarks to locate the anatomical coordinate In this paper, an ultrasound-based approach is proposed that exploits prior knowledge about the anatomy of the pelvis in the form of a 3D surface atlas Tracked ultrasound images are utilized to extract sample points from the surface of the pelvis A generic coordinate system in the specific patient is localized by registering these points to a statistical atlas of the pelvis in which a canonical anatomical coordinate system had been defined This technique has been evaluated using simulation, dry bone, and cadaver experiments, was able to localize the anatomical coordinate system with the accuracy of about 1 degree</p>
