Comparison of linear array B-mode scanning and computed synthetic aperture ultrasonographic imaging

J. Ylitalo
Department of Electrical Engineering, University of Oulu, Finland.

The current trend in ultrasonography is toward digital systems that allow more freedom in beam formation and produce improved images. In this paper, conventional linear array B-mode sonograms of a tissue-mimicking phantom are compared to sonograms obtained with a synthetic aperture technique employing numerical image focusing. Sonograms in both cases were obtained using the same equipment to ensure identical imaging conditions. The computed synthetic aperture approach produced uniform spatial resolution of about 1 mm, which could not be achieved with the B-scan technique. In addition, the contrast resolution of the computed synthetic aperture method was found to be superior. We conclude that the computed synthetic aperture method is feasible for real-time clinical applications.
