Fractal dimensions of the sagittal (interparietal) sutures in humans.
Traditional studies of the cranial suture morphology have focused mostly on visual estimation and linear measurements, and thus on evaluating their complexity. This paper presents a new look on cranial sutures as curves, which can be analysed by fractal dimension. This new measure seems to be a much better method of expressing properties of sutural patterns than traditional methods. Our findings suggest that the fractal dimension of non-complicated interparietal sutures slightly exceeds the topological dimension of the line, that is 1.0, whereas the fractal dimension of complicated sutures may reach a value of 1.4 or even more. The difference between the minimum and maximum decimal fraction of the fractal dimension indicates a three-fold increase in complexity in the investigated sutures.
