On the relationship between encapsulated ultrasound contrast agent and pressure
relationship encapsulated ultrasound contrast agent pressure
2010/1/6
Noninvasive measurement of pressure within the heart cavities and other internal organs
(e.g., kidney, liver) has significant clinical value but currently is not feasible. Noninvasive
pressure estim...
Phase Unwrapping for 2-D Blind Deconvolution of Ultrasound Images
Phase unwrapping Poisson equation multiresolution
2010/1/6
In most approaches to the problem of two-dimensional
homomorphic deconvolution of ultrasound images, the estimation
of a corresponding point-spread function (PSF) is necessarily
the first stage in ...
Calibration Method for Determining the Physical Location of the Ultrasound Image Plane
Calibration Method Determining the Ultrasound Image Plane
2009/12/22
This paper describes a calibration method for determining the physical location of the ultrasound (US) image plane relative to a rigidly attached 3D position sensor. A calibrated US probe can measure ...
Model-Based Reconstructive Elasticity Imaging Using Ultrasound
Model-Based Reconstructive Elasticity Imaging
2009/9/7
Elasticity imaging is a reconstructive imaging technique where tissue motion in response to mechanical excitation is measured using modern imaging systems, and the estimated displacements are then use...
MMSE Reconstruction for 3D Freehand Ultrasound Imaging
MMSE Reconstruction 3D Freehand Ultrasound Imaging
2009/9/4
The reconstruction of 3D ultrasound (US) images from mechanically registered, but otherwise irregularly positioned, B-scan slices is of great interest in image guided therapy procedures. Conventional ...

Superparamagnetic iron oxide nanoparticle-embedded encapsulated microbubbles as dual contrast agents of magnetic resonance and ultrasound imaging
Superparamagnetic iron oxide nanoparticles Encapsulated microbubbles MRI (magnetic resonance imaging)
2010/7/16
An encapsulated microbubble (EMB) of a novel construct is proposed to enhance the magnetic resonance imaging contrast by introducing superparamagnetic iron oxide (SPIO) nanoparticles (mean diameter is...
Electrical impedance tomography imaging using a priori ultrasound data
Electrical tomography imaging a priori ultrasound data
2010/2/26
This paper discusses the combination of ultrasound and electrical impedance tomography (EIT) information. Ultrasound reflection signals are good at locating sharp acoustic density changes associated w...
