The ongoing COVID-19 pandemic has necessitated a comprehensive approach to improve prognostic predictions and manage patient care effectively. One such approach involves the collection and utilization of chest X-ray and CT imaging data. This article will guide you through the process of accessing and utilizing the COVID-19 image dataset while highlighting key features and troubleshooting common issues.

Understanding the Project

The goal of this project is to create a public dataset comprising chest X-ray and CT images from patients with COVID-19 or other respiratory diseases. The data will be sourced from various public and hospital records. An important point to remember is that this is not a Kaggle competition dataset; rigorous evaluation should be ensured.

How to Start Collecting the Data

• View Current Images: You can start by examining the existing images and metadata available in this project. Explore the current image dataset and the associated metadata file.
• Data Loader: An example dataloader can be found here.
• Submission of New Data: Researchers and medical professionals can contribute by submitting relevant data directly to the project.

Labeling and Classification

The images are organized under a hierarchical structure, providing clarity on the various health conditions represented. For instance, the dataset may include images of patients with:

• No Infection
• Bacterial Pneumonia
• COVID-19
• ARDS (Acute Respiratory Distress Syndrome)

The process of classification can be thought of as sorting mail at a post office. Each letter (or image) is examined, and based on its address (or labeling), it is placed into the correct compartment (or category). This ensures organized distribution and retrieval when needed.

Common Goals for Data Utilization

This image dataset can be utilized to develop AI-based approaches that aim to:

• Differentiate between healthy patients and those with pneumonia.
• Predict the severity of pneumonia to guide treatment methods.

Troubleshooting

If you encounter issues while collecting or utilizing the dataset, consider the following troubleshooting steps:

• Access Issues: Ensure you have the necessary permissions or log in correctly to access the data.
• Data Format Errors: Verify that your data matches the required formats: chest X-ray images in dcm, jpg, or png formats; CT scans in nifti format (gzip).
• Submission Problems: If you are having difficulties submitting your data, ensure that your files adhere to the guidelines set out in the metadata schema.
