Inquiry for CT Segmentation Dataset

[yixuanli1230]

I want to inquire about the dataset usage mentioned in your GitHub statement. In your statement, you mentioned, "We trained it on the CNCB CT images with masks ((http://ncov-ai.big.ac.cn/download, Experiment data files): 500 training and 150 for testing taken from COVID-positive patients, but some slices have no lesions."

I would like to know which specific dataset from the website was used for training. Is it from the COVID19-1.zip to COVID19-31.zip dataset? As shown in the figure below.

Thank you for your time and consideration.
