About Caption Health (formerly Bay Labs, now part of GE HealthCare)
Caption Health, formerly known as Bay Labs and now part of GE HealthCare, is a pioneering medical artificial intelligence (AI) company dedicated to expanding access to high-quality ultrasound examinations. The company’s core offering is the Caption AI platform, which utilizes AI to guide healthcare providers, including those without extensive specialized training, in acquiring and interpreting diagnostic-quality ultrasound images. This technology acts as a “co-pilot” during exams, providing real-time guidance on transducer manipulation, automated quality assessment, and intelligent interpretation capabilities, particularly for cardiac ultrasounds.
For physicians, Caption Health’s technology aims to democratize medical imaging by making complex ultrasound procedures more accessible and standardized. The Caption AI platform assists in performing and interpreting echocardiograms, a crucial tool for diagnosing and treating heart disease, by guiding users to capture optimal images and automatically calculating key metrics like ejection fraction. This can lead to earlier disease detection, improved treatment decision-making, and better patient outcomes, especially in settings where expert sonographers may be scarce. Beyond cardiac applications, Caption Health is also developing AI-guided ultrasound technology for pulmonary conditions, with the goal of enabling frontline care providers to effectively use ultrasound for various organ systems.
Caption Health’s technology has received significant recognition, including landmark FDA authorizations for its AI-guided ultrasound software. The company’s solutions are utilized in leading hospitals, clinics, and physician organizations, and have been cited in peer-reviewed journals. The integration with GE HealthCare’s ultrasound business is expected to further expand the reach of Caption AI, embedding it into GE HealthCare’s ultrasound devices, particularly point-of-care and handheld imaging devices.

What Physicians Need to Know
For physicians, Caption Health's AI-guided ultrasound can be a game-changer for point-of-care cardiac assessments. It enables your team, including nurses and hospitalists, to perform diagnostic-quality echocardiograms quickly and efficiently, even without extensive sonography training. This can significantly reduce wait times for crucial cardiac imaging, leading to faster diagnoses and more timely interventions for conditions like heart failure. The automated ejection fraction calculation also provides a reliable, quantitative measurement at the point of care. Consider its use in emergency settings, ICUs, and even for in-home patient assessments to expand access to care and improve early disease detection.
Caption Health's software, Caption Guidance, is designed to be integrated with compatible ultrasound scanners. They have partnered with companies like Butterfly Network to bring AI to handheld ultrasound devices. As part of GE HealthCare, their applications are being integrated into GE HealthCare's ultrasound device portfolios, with plans for expanded future use cases. This suggests a growing ecosystem of compatible hardware and potential for broader integration within existing healthcare IT infrastructures.
