Synthetic Aperture Methods for Medical Ultrasonic Imaging

Synthetic aperture focusing techniques for ultrasonic imaging of solid objects

Synthetic aperture focusing technique (SAFT) has been used in non-destructive testing mainly in its simplest form that mimics acoustic lenses used for focusing ultrasonic beams at a point of a solid object or structure. This paper presents a review of SAFT algorithms applied for post-processing of ultrasonic data acquired in non-destructive inspection of metals. The performance of SAFT in terms...

Ultrasonic Phased Array and Synthetic Aperture Imaging in Concrete

For ultrasound in the hundred kilohertz regime concrete is a very inhomogeneous propagation material. The prescribed definition of aggregates with regard to the respective percentage, the size distribution and the material composition together with the percentage of air inclusions can be realized as a computer model to serve as a platform for elastic wave propagation simulations. As a simulatio...

Synthetic Transmit Aperture Method in Medical Ultrasonic Imaging

The work describes the use of a synthetic transmit aperture (STA) with a single element transmitting and all elements receiving in medical ultrasound imaging. STA technique is a novel approach to today’s commercial systems, where an image is acquired sequentially one image line at a time that puts a strict limit on the frame rate and the amount of data needed for high image quality. The STA ima...

Synthetic aperture ultrasound imaging.

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 sequentially one image line at a time. This puts a strict limit on the frame rate and the possibility of acquiring a sufficient amount of data for high precision flow estimation. These constrictions can be lifted by empl...
