2. How AI Analyzes X-Rays

X-ray analysis was one of the first areas where AI demonstrated clinical value. When a digital X-ray image is captured, it is converted into a matrix of pixels, each with a specific intensity value. AI systems analyze these pixel matrices to identify regions that deviate from normal anatomical patterns.

The AI X-Ray Analysis Process:

  1. Image Capture: Technologist captures high-quality digital X-ray
  2. Preprocessing: AI normalizes brightness, contrast and orientation
  3. Feature Extraction: CNN scans pixel matrix for anomaly patterns
  4. Classification System: Flags regions with confidence scores
  5. Radiologist Review: Final human decision made on AI-flagged areas

What AI Detects in Chest X-Rays:

• Pulmonary Nodules: Small round growths in lung tissue; may indicate early cancer

 • Pneumothorax: Air in the pleural space; collapsed lung requiring urgent care

• Pleural Effusion: Fluid accumulation around the lungs; various underlying causes

• Cardiomegaly: Enlargement of the heart shadow; indicator of cardiac conditions

• Bone Fractures: Cortical breaks in ribs or clavicle; detected by edge analysis
