Abstract
Certain embodiments include a system and method for banding suppression in a B-mode ultrasound image. Banding occurs in a diagnostic image when two or more focal regions having different waveforms and/or frequencies, for example, are combined. The resulting difference in intensity between the focal regions produces banding in the final image. For purposes of illustration only, the method below will be described with two focal zones. Certain embodiments of the present invention reduce banding in a diagnostic image including a plurality of focal zones by processing the first focal zone, determining intensity around the border or “stitch line” between the two focal regions, and adjusting the second focal region based on the difference in intensity. Preferably, processing is done in real time as image frames are updated.
