Ct segmentation challenge
WebThe segmentation performance strongly depends on the intensity, size, and the location of lesions, and can be improved by using specialized loss functions. Specifically, the models performed best in detection of lesions with SUVmax>5.0. Another challenge was to accurately segment lesions close to the bladder. WebIn this challenge, we will provide a dataset of CT scans of patients with nasopharyngeal carcinoma, where the segmentation targets will include OARs, Gross Target Volume of the nasopharynx (GTVnx), and Gross Target Volume of the lymph nodes (GTVnd). The dataset will consist of CT scans from 200 patients (120, 20, and 60 patients for training ...
