Translating this technology from research to clinical practice requires rigorous validation and a clear understanding of its application. The digital twin's ultimate goal is to function as a theranostic tool, both diagnosing the problem and guiding the therapy.
Case Study: Pre-Surgical Optimization for a Hepatocellular Carcinoma Patient
An interventional radiologist is planning a radioembolization procedure. Instead of relying solely on standard imaging, they upload the patient's CT scans to a Digital Twin platform. Within minutes, an AI model generates a 3D vascular map.
The radiologist then virtually places the catheter at three potential injection points. The system, powered by a pre-trained PINN, runs thousands of microsphere simulations for each point, predicting the resulting 3D dose distribution. The platform highlights an injection site that increases the predicted tumor dose by 30% while simultaneously reducing the dose to adjacent healthy liver tissue by 15% compared to the standard approach. This data-driven plan is selected, leading to a more effective and safer treatment.
