on the lung airway s1iov that it has fracta[ featuie. already notice(I by several authors : it is a complex structure vitli a high degree of recursive division (up to 23 levels). and its surface is very large (80 rn2 in average) compared to its volume. The aim of this paper is to use a fractal model to simulate the growth of a lung. In order to construct a meaningful fllO(Iel. we take into account some natural lnvs that rule the grovt1i : maximisatioii of the lung surface. minimisation of its volume. minimisation of the gas tov resistance forces due to the air circulation. border constraints. then make a COIflI)Uter simulation of the iiiorphogenesis to ol)tain a three dimensiounal model of the lung. This model shows good agreement both vith average rnorplonetric data and vith fractal measurement on real lungs. The main problem. however. remains to adjust the different parameters of the model to lit best the (lata. The advantages of such an approach is that it gives a futictionnal knowledge of the lung airway. a rather precise description of the high level branches. which are difficult to observe. and that it could he used to predict evolution under abnormal conditions (for instance border conditions). 10 / SPIE Vol. 1233 Medical Imaging IV: Image Processing (1990)
