Obtaining a distribution of blood flow over distance from ultrasound images. (A) An injury marker and a region of interest including only the perforating vessels were drawn over the images. The distance of each pixel in the region of interest from the injury is shown via the color bar. (B) The post-injury spatial distribution curve (solid red) was constructed by binning pixels into distance bins 0.1 mm in size (not drawn to scale) and calculating the area-adjusted velocity index. Pre-injury spatial distribution in the same rat (dotted black) is also shown for comparison.
