Ultrasound beam forming
Web21 Dec 2015 · Conventional ultrasound (US) image reconstruction methods rely on delay-and-sum (DAS) beamforming, which is a relatively poor solution to the image reconstruction problem. An alternative to DAS consists in using iterative techniques, which require both an accurate measurement model and a strong prior on the image under scrutiny. WebEducators must begin to incorporate this virtual beam-forming into their curricula. Eventually, it will be included in the JRC-DMS National Education Curriculum and the SPI examination content.
