This is a dataset of 100 axial CT images.

Description 

This is a dataset of 100 axial CT images from the Italian Society of Medical and Interventional Radiology’s excellent collection of about 60 patients with Covid-19 that were converted from openly accessible JPG images.

Data type

The database contains 60 cases with example CXRs and single slice CT-images. A simple download from these cases resulted in 110 usable, axial CT-images of confirmed COVID-19 cases.

The images were segmented by a radiologist using 3 labels: ground-glass (mask value =1), consolidation (=2) and pleural effusion (=3). Then they trained a 2d multilabel U-Net model, which you can find and apply in MedSeg. 10 images were left out for validation/testing.

The conversion process is described in detail in the following post: Covid-19 radiology — data collection and preparation for Artificial Intelligence
