On September 9, 2025, the Alliance hosted AI-Assisted Ultrasound: Bridging Innovation and Access in Low-Resource Settings as part of its 2025 AI and Global Health Discussion Series, sponsored by Pfizer. The panel brought together perspectives from across sectors — academics, technology innovators, clinical implementers, funders, and clinicians — including representatives from AMPATH Kenya, the Gates Foundation, the Global Ultrasound Institute (GUSI), Philips Ultrasound, and UCSF’s Bixby Center for Global Reproductive Health. 

Together, the expert panelists explored how AI-assisted ultrasound can transform care in low-resource settings while addressing the challenges of implementation. They discussed its potential to democratize diagnostics — making affordable imaging more accessible for maternal health, cancer, cardiovascular disease, tuberculosis, and other critical conditions where access is too often limited.

Dr. Dilys Walker, director of global research at UCSF’s Bixby Center, framed the discussion by underscoring both the transformative potential and the important questions to consider surrounding AI-assisted ultrasound. “With AI-assisted point-of-care ultrasound (POCUS), we have a powerful step forward with the potential to transform access and ultimately save lives,” she said.

At the same time, Dr. Walker urged the audience to look beyond just the promise and consider the implications of how the technology is developed and deployed. “[AI POCUS] raises serious questions: Are we choosing the right use cases for algorithm development? Who gets to decide which problems AI POCUS should solve? And are designers truly working with limited-resource settings in mind — or might we unintentionally be widening inequities?”

She reminded participants that this is both a moment of optimism and caution. “We are at a truly exciting — but also challenging — moment. The promise of AI POCUS is real, but so are the risks.”

Key Takeaways:

  • AI POCUS should aim to bring diagnostics to patients, rather than the other way around.
  • Affordable, multipurpose AI devices can detect risk and encourage care-seeking behavior.
  • AI POCUS should empower clinicians, not replace them.
  • Local context and health system integration are critical.
  • AI’s impact depends on multi-use design and diverse, locally relevant data.
  • Trust and pacing are essential for meaningful adoption.

The Funder Perspective: Scaling Access and Reducing Costs

Richard Zong, program officer – medical device & AI development at the Gates Foundation, highlighted why the foundation has made AI-assisted ultrasound a priority investment. 

“Training takes time and effort, and point-of-care ultrasound is relatively expensive for what these [low-resource] settings can afford…we wanted to lower the cost of ultrasound and increase accessibility, such that in the long run, people everywhere will have access to the power of ultrasound,” Zong explained, highlighting how in many low- and middle-income countries, particularly at the primary care level, ultrasound remains out of reach. 

Zong shared how the Gates Foundation sees value not only in AI’s capacity to detect risk, but also in its potential to strengthen care-seeking behavior. “We’re really excited about this AI-assisted ultrasound tool not only for its ability to detect risk, but also its ability to bring people to the clinic,” he said, describing a “magnet effect” in which greater accessibility to ultrasound encourages people to come in more frequently and receive more treatment and care.

The ultimate aim, he added, is to maximize both value and reach by building multipurpose devices that integrate several AI applications. “Our goal is to continue partnering with manufacturers to innovate on these solutions so they become lower and lower in cost. As I look towards the future, I’m incredibly excited about how much innovation we can put into AI-assisted ultrasound platforms,” he said, noting the potential and interest to expand beyond obstetrics into lung screening for tuberculosis and pneumonia, gynecological conditions, cardiac care, and even breast cancer.

 

Implementation and Building Capacity at Scale

“Democratizing and decentralizing of imaging allows the clinician to make an earlier, less delayed, less costly, and more upstream diagnosis for that patient … and AI is definitely going to accelerate that and make POCUS even more accessible.” – Dr. Kevin Bergman, GUSI

Dr. Kevin Bergman, co-founder and co-CEO of the Global Ultrasound Institute (GUSI), which has led education and training for the three largest POCUS projects globally, shared his perspective on the current opportunities and biggest risks associated with AI POCUS.

“The fundamental transformation of POCUS is that it brings the diagnostic imaging to where the patient is, instead of sending the patient to where the diagnostic imaging is,” shared Dr. Bergman. “Democratizing and decentralizing of imaging allows the clinician to make an earlier, less delayed, less costly, and more upstream diagnosis for that patient … and AI is definitely going to accelerate that and make POCUS even more accessible.”

Dr. Bergman emphasized five important considerations for integrating AI responsibly into POCUS:

  1. AI should be framed and built as an assist for human clinicians and not a replacement for them.
  2. AI point-of-care ultrasound needs to be designed to build trust. To achieve adoption and ultimately impact, it’s paramount that clinicians trust this tool.
  3. AI is an accelerator of learning ultrasound, not a replacement for knowledge or skills. 
  4. Use diverse data sets with local feedback loops.
  5. Findings on a diagnostic imaging report do not equal a diagnosis; in POCUS, context is everything.

“If we build AI for POCUS that empowers, educates, and includes clinicians, we’ll create stronger, more trusted healthcare,” Dr. Bergman added. “Done right, AI POCUS won’t replace clinicians; they’ll make them faster, better, and more capable.”

Initiating AI-Enabled POCUS Rollout: AMPATH’s Lessons in Western Kenya

AMPATH Kenya’s Dr. Hussein Elias, family physician and lecturer in the Department of Family Medicine at Moi University, and Dr. Daria Szkwarko, family physician and associate professor in the Department of Family Medicine at the Warren Alpert Medical School of Brown University, co-lead one of the largest multi-use point-of-care ultrasound programs in the world, with the goal of deploying more than 600 ultrasound probes and training over 3,000 nurses, midwives, clinical officers, and medical officers across six counties in western Kenya. 

Close collaboration with the Ministry of Health has been key in AMPATH’s work, including county-level agreements detailing all of the steps of focus, education, and clinical integration. The program spans a range of use case topics, including cardiopulmonary disease (particularly heart failure), second- and third-trimester obstetric complications, and breast cancer assessment for patients presenting with palpable masses. “We selected the topics for multiple use cases by considering morbidity and mortality in the rural region in Western Kenya where we practice,” Dr. Szkwarko shared.

“Healthcare workers and patients must trust the technology being integrated — and trust takes time, thoughtful communication, transparency, and reliability.” – Dr. Daria Szkwarko, AMPATH Kenya, Brown University

The team has encountered two main challenges while implementing multi-use POCUS without AI, with plans to integrate AI in the coming months. 

“Healthcare workers are incredibly busy … taking the extra time to document findings in patient books is very challenging. Referral outcomes are also difficult to track at baseline … without investing in additional resources,” explained Dr. Szkwarko, sharing how while they have prioritized sustainability with country-led documentation, this approach has often led to documentation gaps between scans that are performed and those that are actually recorded.

The team also cautioned that even with expanded diagnostics, broader systemic barriers persist. “Although we are implementing an incredible diagnostic tool, we are not changing the state of other social determinants of health in rural Kenya or the state of the health system,” Dr. Elias said, pointing to barriers such as patients’ inability to afford travel or limited availability of biopsies at higher-level facilities. 

As they prepare to integrate AI-assisted ultrasound in the coming months, both emphasized the importance of pacing and trust. “We’re only as good as our health system infrastructure, and we can only move at the speed of trust,” Dr. Szkwarko stressed. “Healthcare workers and patients must trust the technology being integrated — and trust takes time, thoughtful communication, transparency, and reliability.”

Product Development with Patients and Providers in Mind

Jonathan Sutton, senior scientist and group lead at Philips Ultrasound, shared his industry perspective on developing an AI-assisted ultrasound product. “We perceive that there is a major gap in care providers who can consistently assess high-risk pregnancies, and closing it is difficult due to training costs, limited personnel, and uneven health system infrastructure,” Sutton said.

In collaboration with the Gates Foundation, Philips is building a product around that perceived clinical unmet need. “We haven’t released anything to the market yet, but this SmartSweep workflow builds on our handheld Lumify ultrasound platform. After a few hours of training, a clinical user — whether a nurse, midwife, clinical officer, or even a sonographer or OB-GYN — can perform an abdominal scan guided by onscreen prompts and live feedback to ensure the user is following proper ultrasound practices,” shared Sutton.

One thing they are emphasizing is ensuring quality when machine learning is actually involved, with good machine learning practices becoming an essential tenet of their product development process.

“In product development, we focus on understanding user needs by interacting and iterating with clinicians and stakeholders who are actually in the clinical environments. These insights shape our system requirements and software and hardware specifications. We then iteratively test the product with market research, including usability, system, and AI performance validation, before release. We intend to create a platform that can continue improving in accuracy, features, and overall fit for users,” explained Sutton.

 

Collaboration and Trust: Key to AI-Assisted Ultrasound in Low-Resource Settings

“It’s important to think about the contextually relevant AI solutions that can be integrated into the existing infrastructure, which can then be monitored, evaluated, and regulated. Every country is unique in its own way, and it’s about identifying what is truly relevant for each country and how we can put it together so we don’t create parallel systems, but instead work within existing systems to strengthen them.” – Dr. Hussein Elias, AMPATH Kenya, Moi University

While AI-assisted ultrasound technology has the potential to expand access to diagnostics in low-resource settings, its success will hinge on affordability, adequate training, seamless clinical integration, and strengthened referral pathways. A consistent theme emerged across the panel: collaboration and trust are essential to harnessing AI effectively in healthcare. 

“It’s important to think about the contextually relevant AI solutions that can be integrated into the existing infrastructure, which can then be monitored, evaluated, and regulated. Every country is unique in its own way, and it’s about identifying what is truly relevant for each country and how we can put it together so we don’t create parallel systems, but instead work within existing systems to strengthen them,” emphasized Dr. Elias.

Panelists also cautioned that AI and machine learning, though promising, are not silver bullets. Stakeholders must remain both optimistic and critical, championing responsible use and ongoing education. Moving deliberately, leveraging existing systems, and prioritizing contextually relevant solutions are crucial to strengthening healthcare infrastructure. Trust, which is built through people, partnerships, and keeping patients at the center, remains key to meaningful adoption.
