Abstract
The present invention generally relates to ultrasound. In particular, the present invention relates to data dependent color wall filters (used in ultrasound imaging devices for example). Certain embodiments of the present invention relate to a color wall filter that provides flash reduction and clutter suppression. One embodiment of the color wall filter comprises an impulse response filter stage (either a finite or infinite impulse response filter) and a bi-quad filter stage that is data dependent. It is contemplated that the bi-quad filter stage may comprise a series of bi-quad filters, wherein the impulse response filter stage is cascaded into at least one bi-quad filter of the series of bi-quad filters.
