Abstract:
1. A method implemented by an imaging system, comprising: acquiring color Doppler data; detecting one or more border pixels of the color Doppler data; associating each of the one or more border pixels with a respective one of one or more borders; selecting a flow area bounded by a first one of the one or more borders; selecting a first one of the one or more border pixels associated with the first border; detecting a pixel adjacent to the first border pixel, determining whether the adjacent pixel is not one of the one or more border pixels, and, in response to determining that the adjacent pixel is not one of the one or more border pixels, associating the adjacent pixel with the selected flow area; detecting a second pixel adjacent to the adjacent pixel, determining whether the second pixel is not one of the one or more border pixels, and, in response to determining that the second pixel is not one of the one or more border pixels, associating the second pixels with the selected flow area; and detecting a third pixel adjacent to the second pixel, determining whether the third pixel is not one of the one or more border pixels, and, in response to determining that the third pixel is not one of the one or more border pixels, and associating the third pixel with the selected flow area.
