Abstract(in English) | μCT images capture three dimensional structures of tissues with a very high resolution of 100 micrometer or smaller. fine structures such as invasion of lung cancer. However, μCT cannot be used for clinical diagnosis. Although the clinical CT images are used for preoperative diagnosis, it cannot obtain detailed information of tumors. We are planning super-resolution of clinical CT images to μCT-level. As an initial trial, we perform super-resolution of downsampled μCT images to original resolution level. In this paper, we propose Adversarial Dense U-net, based on Dense U-net and Generative Adversarial Network. The network structure including U-net with dense blocks, while a discriminator was used to distinguish whether the output image is a super-resoluted image or an original image. Experiments were performed on μCT images of five cases of dissected lung tissues, and another one case was used for testing. We performed experiments on both 2D and 3D network structure. We evaluated results both quantitatively and qualitatively. Experimental results demonstrated that our proposed method has a SSIM (Structural Similarity) of 0.967 (3D) and 0.946 (2D). |
