• Helps improve AI accuracy over time through expert medical input
• Manages patient cases and medical imaging files (DICOM images)

🎯 Who is this for?

• Physicians who review medical imaging
• Medical students learning about AI in healthcare
• Developers building healthcare applications
• Anyone interested in AI-powered medical technology
