We propose a novel dual dynamic programming (DDP) technique for detecting intimal and adventitial layers of the common carotid artery of the B-mode sonographic images. This method embeds 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 (TDP). Our experimental study shows that the DDP technique achieves a detection performance comparable to manual tracing achieved by physicians. The results demonstrate that it has the potential to perform qualitatively better than applying TDP twice in intimal and adventitial layer detection on sonographic B-mode images.
我们提出了一种新颖的双重动态规划（DDP）技术，用于检测B型超声图像中颈总动脉的内膜层和外膜层。该方法将解剖学知识融入其结构中，从而提高了对斑点噪声的鲁棒性。此外，它继承了传统动态规划（TDP）能够获得最优解的特性。我们的实验研究表明，DDP技术实现了与医生手动追踪相当的检测性能。结果表明，在超声B型图像的内膜层和外膜层检测中，它有可能在定性方面比应用两次TDP表现得更好。
