The paper describes the use of synthetic aperture (SA) imaging in medical ultrasound. SA
imaging is a radical break with today's commercial systems, where the image is acquired …

A new method for acquiring flow images using synthetic aperture techniques in medical
ultrasound is presented. The new approach makes it possible to have a continuous …

This Ph. D. project was carried out at the Center for Fast Ultrasound Imaging, Technical
University of Denmark. The goal was to improve existing imaging techniques in order to …

A method for flow estimation using synthetic aperture imaging and focusing along the flow
direction is presented. The method can find the correct velocity magnitude For any flow …

Conventional ultrasound systems acquire ultrasound data sequentially one image line at a
time. The architecture of these systems is therefore also sequential in nature and processes …

Digital signal processing is being employed more and more in modern ultrasound scanners.
This has made it possible to do dynamic receive focusing for each sample and implement …

The Synthetic Aperture Real-time Ultrasound System (SARUS) for acquiring and processing
synthetic aperture (SA) data for research purposes is described. The specifications and …

This paper investigates the concept of virtual source elements. It suggests a common
framework for increasing the resolution, and penetration depth of several imaging modalities …

Presents a new imaging method, applicable for both 2D and 3D imaging. It is based on
Synthetic Transmit Aperture Focusing, but unlike previous approaches a new frame is …

We propose an all point transmit and receive focusing method based on transmit synthetic
focusing combined with receive dynamic focusing in a linear array transducer. In the …
