A method for defining an area of a component in a blood vessel, wherein the blood vessel is substantially free of a contrast material, the method comprising selecting a first pixel in an image of the blood vessel captured by an ex vivo imager, wherein the selecting is performed at a known position relative to a boundary of the blood vessel in the image; identifying the component from a measure of a brightness of the first pixel, relative to a pre-defined brightness range of the component; and designating a pixel proximate to the first pixel as depicting the component, wherein the designating is based on a brightness of the pixels relative to the first pixel. |
