Among the many challenges in our global healthcare delivery landscape, digital health plays an increasingly important role on almost a daily basis, from personal medical devices, to wearables, to new clinical technology and data exchanges. Beyond direct patient care, digital health also applies to diagnostics, drug effectiveness, and treatment delivery. These use cases are being driven by rapid growth in data modeling, artificial intelligence (AI)/machine learning (ML), and data visualization. Given the rapid digitalization of healthcare delivery, emerging digital twin technology is considered the next system that will advance further efforts in medical discoveries and improve clinical and public health outcomes.

What is a Digital Twin?

Put simply, a digital twin is a digital replica or “twin” of a physical object, process, or service. It is a virtual model (a compilation of data plus algorithms) that can dynamically pair the physical and digital worlds. The ultimate goal for digital twins, such as in manufacturing, is to iteratively model, test, and optimize a physical object in the virtual space until that model meets expected performance, at which point it is then ready to be built or enhanced (if already built) in the physical world. To create a pairing between the digital world and the real world, a digital twin leverages real time data, such as smart sensor technology, coupled with analytics, and often artificial intelligence (AI) in order to detect and prevent system failures, improve system performance, and explore innovative uses or functional models.

As mentioned, developments in smart sensor technologies and wireless networks have pushed forward the applications of the Internet of Things (IoT), and contributed to the practical applications of digital twin technology. Thanks to IoT, cloud computing and real time analytics, digital twins can now be created to collect much more real-world and real-time data from a wide range of sources, and thus can establish and maintain more comprehensive simulations of physical entities, their functionality, and changes they undergo over time.

Digital Twins in Healthcare

While the application of digital twins in healthcare is still very new, there are three general categories for their use: digital twins of a patient/person or a body system; digital twins of an organ or a smaller unit; and digital twins of an organization.

Digital twins can simulate the whole human body, as well as a particular body system or body function (e.g., the digestive system). One example of this kind of patient-sized digital twin is the University of Miami’s MLBox system, designed for the measurement of a patient’s “biological, clinical, behavioral and environmental data” to design personalized treatments for sleep issues.

Digital twins can also simulate one body organ, part of an organ or system, like the heart, and can even model subcellular (organelle/sub-organelle) functions or functions at the molecular level of interest within a cell. Dassault Systèmes’ Living Heart Project is an example of this kind of digital twin, which is designed to simulate the human heart’s reaction to implantation of cardiovascular devices.

Additionally, healthcare institutions (e.g., a hospital) can have their corresponding digital twins, such as Singapore General Hospital. This kind of simulation can be useful when determining environmental risks within institutions, such as the risks of infectious disease transmission.

The “Heart” of Health Digital Twins is Open Source – and the LF

While digital twins represent a complex and sophisticated new digital model, the building blocks of this technology—like all other software foundations—are best supported by an open-source development and governance model. The Linux Foundation sustains the nexus of open source development that underpins digital twin technology:

Linux Foundation Public Health (LFPH) is dedicated to advancing open source software development for digital health applications across the globe. Together with its members, LFPH is developing projects that address public health data infrastructure, improving health equity, advancing cybersecurity, and building multi-stakeholder collaboration for patient engagement and health information exchange.
The LF AI and Data Foundation is working to build and support an open artificial intelligence (AI) and data community, and drive open source innovation in the AI and data domains by enabling collaboration and the creation of new opportunities for all the members of the community.
LF Edge aims to establish an open, interoperable framework for edge computing independent of hardware, silicon, cloud, or operating system. By bringing together industry leaders, LF Edge will create a common framework for hardware and software standards and best practices critical to sustaining current and future generations of IoT and edge devices.
The Open 3D Foundation includes many collaborators working to make an open source, fully-featured, high-fidelity, realtime 3D engine for building games and simulations, such as digital twins, available to every industry. “The Open 3D Foundation, along with its partners and community is helping advance 3D digital twin technology by proving an open source implementation that is completely dynamic with no need to preload the media.” said General manager Royal O’Brien, “This can ensure the smallest customizable footprint possible for any device platform to meet any industry needs.”

Additionally, LFPH has established a joint membership with the Digital Twin Consortium, focused on healthcare and life sciences. “Artificial Intelligence (AI), edge computing and digital twins represent the next generation in data transformation and patient engagement,” said Jim St. Clair, Executive Director, “Developing a collaborative relationship with the Digital Twin Consortium will greatly advance the joint efforts of model development and supporting open source components to advance adoption in healthcare through multi-stakeholder collaboration.” LFPH looks forward to supporting, innovating, and driving forward an open-source vision in the critical and growing area of digital twins for healthcare.

The role of software, specifically open source software, is more influential than ever and drives today’s innovation. Maintaining and growing future innovation depends on the open source community. Enterprises that understand this are driving transformation and rising to the challenges by boosting their collaboration across industries, understanding how to support their open source developers, and contributing to the open source community.

They realize that success depends on a cohesive, dedicated, and passionate open source community, from hundreds to thousands of individuals. Their collaboration is key to achieving the project’s goals.   It can be challenging to manage all aspects of an open source project considering all the different parts that drive it. For example:

Project’s scope and goals
Participating members, maintainers, and collaborators
Management and governance
Legal guidelines and procedures
IT services 
Source control, CI/CD, distribution, and cloud providers
Communication channels and social media

The Linux Foundation’s LFX provides various tools to help open source communities design and adopt a successful project strategy considering all moving parts. So how do they do it? Let’s explore that using the Hyperledger project as an example. 

1. Understand your project’s participation

Through the LFX Individual Dashboard, participants can register the identity they are using to contribute their code to GitHub and Gerrit (Since the Hyperledger project uses both). Then, the tool uses that identity to connect users’ contributions, affiliations, memberships, training, certifications, earned badges, and general information. 

With this information, other LFX tools gather and propagate data charts to help the community visualize their participation in GitHub and Gerrit for the different Hyperledger repositories. It also displays detailed contribution metrics, code participation, and issue participation.  

The LFX Organization Dashboard is a convenient tool to help managers and organizations manage their project memberships, discover similar projects to join, and understand the team’s engagement in the community. In detail, it provides information on:

Code contributions
Committee members
Event speakers and attendees 
Training and certification
Project enrollments

It is vital to have the project’s members and participant identities organized to understand better how their work makes a difference in the project and how their participation interacts with others toward the project’s goals.  

2. Manage your project’s processes

LFX Project Control Center offers a one-stop portal for program managers to organize their project participation, IT services, and quick access to other LFX tools.

Project managers can also connect:

Their project’s source control
Issue tracking tool
Distribution service
Cloud provider
Mail lists
Meeting management
Wiki and hosted domains 

For example, Hyperledger can view all related organizations under their Hyperledger Foundation umbrella, analyze each participant project, and connect services like GitHub, Jira, Confluence, and their communication channels like Groups.io and Twitter accounts.

Managing all the project’s aspects in one place makes it easier for managers to visualize their project scope and better understand how all their services impact the project’s performance.

3. Reach outside and get your project in the spotlight

Social and earned media are vital to ensure your project reaches the ears of its consumers. In addition, it is essential to have good visibility into your project’s influence in the Open Source world and where it is making the best impact.

LFX’s Insights Social Media Metrics provides high-level metrics on a project’s social media account like:

Twitter followers and following information 
Tweets and retweet breakdown
Trending tweets
Hashtag breakdown 
Contributor and user mentions

In the case of Hyperledger, we have an overall view of their tweet and retweet breakdown. In addition, we can also see how tweets by Bitcoin News are making an impression on the interested communities. 

Insights help you analyze how your project impacts other regions, reaches diverse audiences by language, and adjust communication and marketing strategies to reach out to the sources that open source participants rely on to get the latest information on how the community contributes and engages with others. For example, tweets written in English, Japanese, and Spanish made by Hyperledger contributors are visible in an overall languages chart with direct and indirect impressions calculated.

The bottom line

A coherent open source project strategy is a crucial driver of how enterprises manage their open source programs across their organization and industry. LFX is one of the tools that make enterprise open source programs successful. It is an exclusive benefit for Linux Foundation members and projects. If your organization and project would like to join us, learn more about membership or hosting your project.
