Due to rising skepticism towards the sensitivity of<br>\nRT-PCR as screening method, medical imaging like computed<br>\ntomography offers great potential as alternative. For this<br>\nreason, automated image 分割 is highly desired as<br>\n临床决策支持 for quantitative assessment and<br>\ndisease monitoring. However, publicly available 新冠肺炎<br>\nimaging data is limited which leads to overfitting of traditional<br>\napproaches. To address this problem, we propose an innovative<br>\nautomated 分割 pipeline for 新冠肺炎 infected<br>\nregions, which is able to handle small datasets by utilization as<br>\nvariant databases. Our method focuses on on-the-fly<br>\ngeneration of unique and random image patches for training<br>\nby performing several preprocessing methods and exploiting<br>\nextensive data augmentation. For further reduction of the<br>\noverfitting risk, we implemented a standard 3D U-Net<br>\narchitecture instead of new or computational complex neural<br>\nnetwork architectures. Through a 5-fold cross-validation on 20<br>\nCT scans of 新冠肺炎 patients, we were able to develop a<br>\nhighly accurate as well as robust 分割 model for lungs<br>\nand 新冠肺炎 infected regions without overfitting on the<br>\nlimited data. Our method achieved Dice similarity coefficients<br>\nof 0.956 for lungs and 0.761 for infection. We demonstrated<br>\nthat the proposed method outperforms related approaches,<br>\nadvances the state-of-the-art for 新冠肺炎 分割 and<br>\nimproves 医学图像分析 with limited data.
