Abstract

This paper presents a new Chain-Code algorithm based on eight-direction tracing. Whole code area is divided into four quadrants by this method. In each quadrant, the tracing order is different, but accord with holistic direction. Using the Chain-code tracing method and tracing the contour, a closed contour's information is obtained. By this tracing principle, all contours' information in the chain-code is gotten finally. Isodose curve with same dose, which is appeared several times in medical image process, is solved by this tracing principle. Using the chain-code in order, the original isodose curves can be drawn. However it need to be approximated and smoothed. The distance is taken as the intermediate variable, and the relationship of coordinate x and y translate into the relationship of distance and coordinate. It is convenient to smooth the isodose curve and get the ideal isodose information. The satisfactory result of isodose in 3-D medical image process is shown in this paper.
