Digital Twin
It is not a new trend since NASA had used first mock-up in the 1960s during their space mission Apollo 13 to replicate the physical systems present in aircraft at ground for troubleshooting and maintenance. In 2002, Dr. Michael Grieves first used the term Digital Twin. It is a virtual representation of physical assets, operational processes, people, or places. It shows the visualization of complex assets and processes and helps businesses to improve their performance. Digital Twin can perform bi-directional automated data flow between the physical object and digital representation.
Digital Twin embraces four technologies to create visual representation, capture, store, analyse data and provide valuable insights. These technologies are the IoT, Extended Reality (XR), Cloud, and Artificial Intelligence (AI).
Benefits
Major benefits of Digital Twins include remote visibility of assets, systems, processes, and understanding the behaviour of physical device. With asset behaviour insights, it runs prediction algorithm to predict the future. Also, these insights aid better decision making and automate the decision-making process, optimising productivity, and profitability. Additionally, it also performs risk analysis on different what-if scenarios and help businesses to maximise operational efficiency. Comparing Digital Twin with Digital Simulation, simulation is static and does not update in real-time, while Digital Twin is dynamic and get real-time updates from physical asset, system, or process. Thus, it produces more accurate outputs for business decisions.
Digital Twin has extensive applications in various industries like Healthcare, Manufacturing, Automotive, Utilities and Smart City. Gartner predicts that by 2021, approx. 50% of large companies will utilize digital twins and improve their internal efficiency by 10%.
Let us look at few Digital Twin use cases in the medical domain.
Patient Digital Twin – Enabling Personalised Care
Patient’s Digital Twin is designed to capture continuous data from the individual about various vitals, medical condition, response to the drug, therapy, and surrounding ecosystem. Each patient’s data is stored at Azure or AWS public cloud and fed to the Digital Twin platform. Historic and real-time data of each patient helps ML algorithm to predict future health conditions. With lifestyle, daily food habits and blood sugar data of chronic diabetes patient, model alerts the patient for medications, food habit changes, doctor consultation etc. Thus, Digital Twin leverages a large amount of rich data from various IoMT devices and uses AI-powered models to develop more personalized and better care plans.
Unique Digital Twin from each patient help in determining right therapy, predict the outcome of a specific procedure and manage the chronic disease for them using insights from historical data. Consider a scenario of heart failure patient who needs a Cardiac Resynchronization Therapy (CRT) by implanting a pacemaker. Due to different heart characteristics, few patients do not respond to the therapy. Also, for the right patients, the placement must be precise to avoid future risks. By leveraging patients MRI, ECG and Blood Pressure data, Digital Twin of the patient heart is created, and it helps cardiologists to define the position of leads and virtually experimenting the placement before intervention surgery.
Another example is right therapy decision support for cancer treatment. Digital Twin with patient’s imaging data, genetic data and laboratory results helps the doctor to decide optimum treatment from surgery, radiation therapy or hormone therapy. To manage chronic disease in a large population, Digital Twin helps in detecting chronic disease in an earlier stage by analysing physiological and behavioural data.
Hospital Digital Twin – Improving Operational Efficiency
Initially, Digital Twin was limited to a single device or component but with emergence in Artificial Intelligence (AI) technology, Digital Twin now has evolved and can represent an entire complex system, process, or place. Digital Twin of various hospital business processes helps in optimizing and improving the entire ecosystem. It models so many dimensions of hospital facility including the movement of doctors, patients, equipment and with real-time location tracking of systems, assets, and people. Using real-time data availability from entire hospital data points, the AI model can simulate the improved efficiency. The model algorithm can consolidate the results from imaging and non-imaging laboratory diagnosis and can present results which help the physician to make a better decision.
Siemens Healthineers created Digital Twin model representation for radiology department of one of the customers after analysing their process and operations. Such simulation optimizes the process and improves the patient experience by reducing long wait times, effectively managing emergency services, optimum utilization of lab and medical equipment, staffing requirement and managing devices downtime. Thus, hospital management can monitor the entire infrastructure from a unified platform – patient to clinicians to data to workflows.
Simulated Training
The idea of Digital Twin in medical training and diagnostics is a patient model created before actual surgery and virtual surgery is performed from the multidisciplinary team on it to avoid damage of human anatomy. This real-time model also allows residents to do surgery simulation on patients and help them to understand each patient’s physiological and anatomical differences. One of the examples of diagnostics using Digital Twin model is CardioInsight mapping system from Medtronic which collects and combines the patient body surface electrical data with heart-torse anatomical data and provide a 3D map of heart’s electrical activity. This diagnostics method has also received an approval from the FDA.
