title = "CPSS-Net: A Cross-pseudo Semi-supervised Network for Liver Vessel Segmentation from CTA Images",
abstract = "Accurate segmentation of liver vessel from CTA images is often challenging due to the limited availability of labeled data. In the field of medical image segmentation, semi-supervised learning has garnered significant attention as it utilizes unlabeled data to enhance the training of segmentation models. In this paper, we propose a novel cross-pseudo semi-supervised network (CPSS-Net) based on nnU-Net. The CPSS-Net contains three innovative components: 1) An probability prediction (PP) module is designed to generate probability maps for both labeled and unlabeled datasets, capturing model uncertainty through parallel nnU-Net; 2) A double pseudo-label (DPL) module is used to convert the predicted probability maps into double soft pseudo-labels using an adaptive sharpening function; 3) A cross pseudo-supervised (CPS) module is introduced to learn the mutual consistency of double pseudo-labels. Test experiments on both public and private datasets show that our method achieved a Dice score of 0.67 and a sensitivity score of 0.69, surpassing the segmentation accuracy of existing related methods.",
