A posteriori accuracy estimation of ultrasonic vector-flow mapping (VFM).

Abstract: A novel method, called a posteriori "VFM accuracy estimation" (VAE), for resolving an intrinsic VFM problem is proposed. The problem is that VFM uncertainty can easily vary according to blood flows through an echocardiographic imaged plane (i.e.

Accuracy and limitations of vector flow mapping: left ventricular phantom validation using stereo particle image velocimetory.

Background: The accuracy of vector flow mapping (VFM) was investigated in comparison to stereo particle image velocimetry (stereo-PIV) measurements using a left ventricular phantom. VFM is an echocardiographic approach to visualizing two-dimensional flow dynamics by estimating the azimuthal component of flow from the mass-conservation equation. VFM provides means of visualizing cardiac flow, but there has not been a study that compared the flow estimated by VFM to the flow data acquired by other methods.

Experimental study on temperature rise of acoustic radiation force elastography.

Introduction: Acoustic radiation force (ARF) elastography is potentially useful for imaging the elasticity of human tissue. Because a "push wave" that is used to generate ARF is a long burst wave comparable to that used in regular clinical imaging, detailed investigation of its safety is required.

Materials And Methods: We focus on the transient temperature rise in the far field, where the beam paths are overlapped.
