Using Dual Dynamic Programming for Artery’s Inner Wall Detection in Sonographic Images

We propose a novel dual dynamic programming in detecting dual contours on medical images such as intimal and adventitial layers of common carotid artery (CCA) of the B-mode sonographic images. This method has embedded the anatomic knowledge into its structure so that the robustness against the speckles is increased. Moreover, it inherits the property of getting the optimal solution as the traditional dynamic programming. We compare the automated results with the manual tracing and the accuracy is convinced. Our study shows that the dual dynamic programming outperforms the previous methods in intima-media thickness measurement.
