Fecha de publicación: | jul-2012 | Editor: | Institute of Electrical and Electronics Engineers | Citación: | IEEE Transactions on Ultrasonics Ferroelectrics and Frequency Control | Resumen: | The design of newer ultrasonic imaging systems attempts to obtain low-cost, small-sized devices with reduced power consumption that are capable of reaching high frame rates with high image quality. In this regard, synthetic aperture techniques have been very useful. They reduce hardware requirements and accelerate information capture. However, the beamforming process is still very slow, limiting the overall speed of the system. Recently, general-purpose computing on graphics processing unit techniques have been proposed as a way to accelerate image composition. They provide excellent computing power with which a very large volume of data can easily and quickly be processed. This paper describes a new system architecture that merges both principles. Thus, using a minimum-redundancy synthetic aperture technique to acquire the signals (2R-SAFT), and a graphics processing unit as a beamformer, we have developed a new scanner with full dynamic focusing, both on emission and reception, that attains real-time imaging with very few resources. | Versión del editor: | http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6242797 http://ieeexplore.ieee.org/search/searchresult.jsp?newsearch=true&queryText=An+ultrasonic+imaging+system+based+on+a+new+SAFT+approach+and+a+GPU+beamformer.&x=33&y=16 10.1109/TUFFC.2012.2341 |
