Abstract
Sidelobe and clutter suppression techniques in ultrasound imaging are described and referred to as Dual Apodization with Cross-correlation or 'DAX'. DAX dramatically improves the contrast-to-noise ratio (CNR) allowing for easier visualization of anechoic cysts and blood vessels. These techniques use dual apodization or weighting strategies that are effective in removing or minimizing clutter and efficient in terms of computational load and hardware/software needs. This dual apodization allows for determination of the amount of mainlobe versus clutter contribution in a signal by cross-correlating RF data acquired from two apodization functions.
