Current status and future developments of contrast-enhanced ultrasound of carotid atherosclerosis.
B-mode and Doppler ultrasound are commonly used for the evaluation of atherosclerosis in the carotid arteries. Recently, contrast-enhanced ultrasound (CEUS) has been introduced as a technique toExpand

Dedicated ultrasound speckle tracking to study tendon displacement
Ultrasound can be used to study tendon and muscle movement. However, quantization is mostly based on manual tracking of anatomical landmarks such as the musculotendinous junction, limiting theExpand

Cardiac Shear Wave Velocity Detection in the Porcine Heart.
Cardiac muscle stiffness can potentially be estimated non-invasively with shear wave elastography. Shear waves are present on the septal wall after mitral and aortic valve closure, thus providing anExpand

Subharmonic, non-linear fundamental and ultraharmonic imaging of microbubble contrast at high frequencies.
There is increasing use of ultrasound contrast agent in high-frequency ultrasound imaging. However, conventional contrast detection methods perform poorly at high frequencies. We performed systematicExpand

Myocardial passive shear wave detection
We studied the mechanical waves after mitral and aortic valve closure in the septal wall of 34 pigs (18 diabetic for heart failure and 16 controls), using high frame rate imaging on a programmableExpand
