Abstract
Flash artifacts in ultrasound flow images are suppressed to achieve enhanced flow discrimination. Flash artifacts typically occur as regions of elevated signal strength (brightness or equivalent color) within an image. A flash suppression algorithm includes the steps of estimating the flash within an image and then suppressing the estimated flash. The mechanism for flash suppression is spatial filtering. An extension of this basic method uses information from adjacent frames to estimate the flash and/or to smooth the resulting image sequence. Temporal information from adjacent frames is used as an adjunct to improve performance.
