Item Open Access Erratum to "Equivalent circuit-based analysis of CMUT cell dynamics in arrays" [May 13 1016-1024](IEEE, 2013-06-03) Oguz, H. K.; Atalar, Abdullah; Köymen, HayrettinIn the original publication of the paper [1], the funding source was inadvertently omitted from the footnote on page 1016. The footnote should have read "Manuscript received November 20, 2012; accepted February 14, 2013. This work was supported by the Scientific and Technological Research Council of Turkey (TUBITAK) under project grant 110E216. A. Atalar acknowledges the support of the Turkish Academy of Sciences (TUBA)." The authors regret this omission.Item Open Access A VLSI receive beamformer for digital ultrasound imaging(IEEE, 1992-03) Karaman, Mustafa; Kolağasıoğlu, Ertuğrul; Atalar, AbdullahA VLSI architecture for real-time digital receive beamforming in phased array ultrasound imaging is proposed. The architecture is an inverse binary tree like structure with N stages where N is the number of array elements. The sampled signals from the phased array channels are coherently added in a pairwise manner within the stages of the architecture in a pipelined data flow scheme. The storage requirement for the synchronization of the asynchronously received samples corresponding to a focal point is significantly reduced. The architecture is modular and has a regular communication scheme which make the VLSI implementation rather easy and straightforward.
