Introduction
Imagine a virtual replica of a patient—a digital model capturing everything from their genomic data to real-time physiological responses. This concept, known as a “digital twin,” is no longer confined to manufacturing industries or supply chain management; it’s making significant inroads into modern healthcare. Digital twins allow clinicians, researchers, and caregivers to simulate treatment scenarios, forecast patient outcomes, and personalize therapy with unprecedented accuracy.
The basic principle of a digital twin is simple yet transformative: replicate a physical object, system, or person into a virtual environment where data-driven analyses can be performed without risk to the actual subject. These virtual simulations not only reduce healthcare costs over time but also facilitate proactive, patient-centered care that was previously out of reach for many providers. Today, the question isn’t whether digital twins will permeate healthcare, but rather how quickly they will become a vital part of clinical workflows.
