Abstract This paper investigates an effective enhancement method for CT pulmonary vessel by using structure tensor. Firstly, based on a calculated image’s structure tensor, the image’s diffusion tensor is constructed. Then, the diffusion tensor is filtered with three different schemes. Finally, the result shows the effective of the proposed method. The synthetic dataset and CT Lung dataset from LIDC are used to verify this method’s efficiency. The result shows the pulmonary vessels are enhanced and the images’ contrast and SNR are improved. The enhancement method based on structure tensor is suitable for CT pulmonary vessel.
