Automatic segmentation of the lumen region in intravascular images of the coronary artery

101Example of the output images resulting from each step of the automatic segmentation of the lumen in one IVUS image (the green contour in the image on the right of the lumen identification step represents the final segmentation result). (The identification of the bifurcation region step is not illustrated in this example since there was no side branch in the IVUS image used.)
