From Lungs to Hearts: How Digital Twins Are Revolutionizing Indian Healthcare

Digital twin technology—virtual replicas of organs or entire patient systems—is rapidly emerging as a game‑changer in India’s healthcare ecosystem. By integrating AI, imaging, and real‑time patient data, digital twins enable predictive diagnostics, personalized treatment, and advanced surgical planning.

What is a Digital Twin in Healthcare?

• A digital twin is a virtual model of a patient’s body or organ, created using CT scans, vitals, lab reports, and wearable data.
• Doctors can simulate disease progression, predict treatment responses, and plan interventions with greater accuracy.
• It combines AI, IoT, big data, and imaging workflows for real‑time monitoring and diagnostics.
