Optimizing Synthetic Aperture Compound Imaging 10.1109/ULTSYM.2012.0094

Hansen, Jens Munk; Jensen, Jørgen Arendt

Proceedings of Ieee International Ultrasonics Symposium. Ieee, 2012 — 2012, pp. 382-385

Spatial compound images are constructed from synthetic aperture data acquired using a linear phased-array transducer. Compound images of wires, tissue, and cysts are created using a method, which allows both transmit and receive compounding without any loss in temporal resolution. Similarly

Compounding in synthetic aperture imaging 10.1109/TUFFC.2012.2427

Hansen, J. M.; Jensen, J. A.

I E E E Transactions on Ultrasonics, Ferroelectrics and Frequency Control — 2012, Volume 59, Issue 9, pp. 2054-2065

A method for obtaining compound images using synthetic aperture data is investigated using a convex array transducer. The new approach allows spatial compounding to be performed for any number of angles without reducing the frame rate or temporal resolution. This important feature is an intrinsic

Performance of Synthetic Aperture Compounding for in-vivo imaging 10.1109/ULTSYM.2011.0282

Hansen, Jens Munk; Jensen, Jørgen Arendt

Proceedings of Ieee International Ultrasonics Symposium — 2011, pp. 1148-1151

. The water tank measurements reveal an improved detail resolution of 45% when comparing SAC to conventional compounding and an improvement of 22%, when comparing to synthetic aperture (SA) imaging. The cystic resolution at 12 dB is improved by 50% and 12% when comparing SAC to conventional compounding and SA

Compound imaging using Synthetic Aperture Sequential Beamformation 10.1109/ULTSYM.2011.0565

Jensen, Casper Bo; Jensen, Jonas; Hemmsen, Martin Christian; Hansen, Jens Munk; Jensen, Jørgen Arendt

Proceedings of 2011 Ieee International Ultrasonics Symposium — 2011, pp. 2277-2280

Synthetic Aperture Sequential Beamforming (SASB) is a technique with low complexity and the ability to yield a more uniform lateral resolution with range. However, the presence of speckle artifacts in ultrasound images degrades the contrast. In conventional imaging speckle is reduced by using
