                  This paper presents a new blood flow detection scheme, where a
                  novel painting segmentation algorithm is utilized in order to 
                  achieve the accurate area of lumens within carotid artery 
                  B-mode ultrasound images. The scheme allows for user-defined 
                  thresholding providing tolerance levels within the contour 
                  detection process in order to overcome crippling interference
                  noise and degrading artifacts in ultrasound images. Since 
                  plaque buildup obstructs the flow of blood in the carotid 
                  artery, this scheme can identify these severe plaque-thickened
                  inflamed regions, through detecting high and low levels of
                  blood flow.
