An Intravascular Ultrasonic Imaging Technique for Measurement of Elastic Properties of the Artery

1993
In recent years, intravascular ultrasonic imaging has become important as this technique provides cross-sectional images of the arterial wall. Several in vitro studies1–3 demonstrate good correlation for the lumen or the wall thickness between ultrasound images and histological sections.

10B-6 A Composite Imaging Technique for High Frame-Rate and Full-View Cardiovascular Ultrasound and Elasticity Imaging

2007 IEEE Ultrasonics Symposium Proceedings, 2007
The frame-rate of ultrasound radio-frequency (RF) data acquisition is critical for imaging of the pulse wave and electromechanical wave propagation in cardiovascular tissues as well as improving the strain estimation. Therefore, an automated method had been developed to overcome the frame-rate limitations on standard systems by retrospective multi ...

Evaluation Of An Elastic Curve Technique For Finding The Auroral Oval From Satellite Images Automatically

IEEE Transactions on Geoscience and Remote Sensing, 1990
An automated algorithm for finding the inner boundary based on recently proposed computer vision technique is described. The algorithm is analogous to solving the equations of motion for an elastic curve, where the forces are provided by the image. The resulting equilibrium position of the elastic curve provides an automated method for finding the ...

Comb-push Ultrasound Shear Elastography (CUSE): A novel and fast technique for shear elasticity imaging

2012 IEEE International Ultrasonics Symposium, 2012
Multiple push-detect acquisitions are typically required in current acoustic radiation force based shear wave elasticity imaging methods to reconstruct a full FOV elasticity map, which can result in potential motion artifacts and difficulties in studying tissue dynamic mechanical properties. Comb-push Ultrasound Shear Elastography (CUSE) is a novel and

Synthetic Aperture Focusing Technique and Contrast Source Inversion Algorithm Applied in Elastic Wave Imaging

Advanced Materials Research, 2011
In this paper the linear synthetic aperture focusing technique (SAFT), the nonlinear contrast source inversion (CSI) algorithm and the CSI algorithm with extended approaches, such as frequency approach and regularization approach, are applied to reconstruct a complicated target immersed in water from the experimental elastic wave data.

3D imaging of light elements using elastic scattering coincidence technique

2008
We describe setup for elastic scattering coincidence technique at the Zagreb microprobe. It is developed for 3-dimensional profiling of small concentration of light elements in heavier matrices. The method is based on the elastic scattering coincidence technique.

3-D Elastic Matching Technique for Temporal Subtraction Employing Thorax MDCT Images

2007
Detection of subtle lesions on CT images is a difficult task for radiologists, because subtle shadows tend to have low contrast, and a large number of CT images must be interpreted in a limited time. A temporal subtraction image, which is obtained by subtraction of a previous image from a current one, can be used for enhancing interval changes (such as
