High-frequency ultrasonic pulses at 36 MHz are used to measure velocity profiles in a
complex fluid sheared in the Couette geometry. Our technique is based on time-domain …

Background Stroke is in the top three leading causes of death worldwide. Non-invasive
monitoring of stroke can be accomplished via stenosis measurements. The current …

A new estimator for determining the two-dimensional velocity vector using a pulsed
ultrasound field is derived. The estimator uses a transversely modulated ultrasound field for …

Ultrasound (US) localization microscopy offers new radiation-free diagnostic tools for
vascular imaging deep within the tissue. Sequential localization of echoes returned from …

These notes have been prepared for the international summer school on advanced
ultrasound imaging sponsored by The Danish Research Academy. The notes should be …

Speckle noise negatively affects medical ultrasound image shape interpretation and
boundary detection. Speckle removal filters are widely used to selectively remove speckle …

The quality of ultrasound color flow images is highly dependent on sufficient attenuation of
the clutter signals originating from stationary and slowly moving tissue. Without sufficient …

Programs capable of simulating ultrasound images have recently been developed. This
opens the possibility of evaluating transducers and focusing schemes not only from their …

As uses for ultrasound increase, so does the need for effective signal processing
techniques. In this article we provide an overview of signal acquisition and processing in …

Synthetic aperture (SA) can be used for both anatomic and functional imaging, where tissue
motion and blood velocity are revealed. Often, sequences optimized for anatomic B-mode …
