About Caption Health

Caption Health, formerly known as Bay Labs, is a healthcare AI company that develops AI-guided medical imaging software. Their core mission is to democratize access to ultrasound technology by enabling a broader range of healthcare providers to perform and interpret ultrasound exams. The company’s flagship product, Caption AI, acts as a “co-pilot” for clinicians, providing real-time guidance, automated quality assessment, and intelligent interpretation capabilities during ultrasound examinations. This technology aims to make complex ultrasound procedures, traditionally requiring years of specialized training, more accessible and standardized, ultimately improving diagnostic accuracy and efficiency at the point of care.

Caption Health’s technology has received landmark authorization from the FDA for its AI-guided image acquisition system, particularly for cardiac ultrasound. This allows healthcare professionals, including those without extensive prior ultrasound experience, to acquire high-quality cardiac ultrasound images for diagnosing and treating heart conditions. The company is also developing ultrasound applications for pulmonary conditions, supported by grants from organizations like the Bill & Melinda Gates Foundation. In 2023, Caption Health was acquired by GE HealthCare, integrating its AI-powered ultrasound platform into GE’s broader digital ecosystem and ultrasound business.

What Physicians Need to Know

AI-Powered Ultrasound Imaging
Caption Health specializes in AI-powered ultrasound imaging, particularly for cardiac assessments. Their flagship product, Caption AI, includes Caption Guidance software, which uses artificial intelligence to provide real-time guidance and diagnostic quality assessment of images. This technology enables healthcare providers, even those without prior ultrasound experience, to capture diagnostic-quality cardiac ultrasound images. They are also expanding their AI technology to lung ultrasound.
Cardiac Function Assessment
Caption Health's technology focuses on cardiac function assessment, including automated ejection fraction (EF) interpretation. Their Caption Interpretation software uses deep learning to automatically select the best clips from ultrasound exams, perform quality assurance, and produce accurate EF measurements, incorporating three ultrasound views (apical 4-chamber, apical 2-chamber, and parasternal long-axis). This allows for quick, easy, and accurate assessments of cardiac function at the point of care.
Early Disease Detection & Democratizing Medical Imaging
Caption Health aims to democratize medical imaging and enable early disease detection by making ultrasound more accessible. Their AI-guided system allows non-specialists, such as nurses and medical assistants, to perform cardiac ultrasound exams, which can lead to earlier identification of conditions like heart failure. This expands access to diagnostic-quality imaging in various settings, including doctors' offices, critical care units, emergency rooms, and even in-home care.
AI-Guided Image Acquisition
Caption Guidance, their AI-powered software, acts as a 'co-pilot' for clinicians during ultrasound exams. It provides real-time, turn-by-turn instructions on how to manipulate the transducer and offers automated feedback on diagnostic image quality. The software can automatically capture the optimal clip when the image reaches diagnostic quality, eliminating the need for manual intervention and reducing suboptimal clips.
Key Differentiators
Caption Health was the first company to receive FDA authorization for an AI-guided medical imaging acquisition system (Caption Guidance) in February 2020. Their technology enables healthcare providers without extensive ultrasound experience to acquire and interpret high-quality cardiac ultrasound exams. Caption Interpretation is also noted as being able to analyze every pixel and frame in a given clip for highly accurate EF measurements, a capability they claim is unique among commercially available EF measurement software. They have also received a CE Mark for their Caption AI platform, expanding its availability outside the US.
Technology Stack
Caption Health's technology is built on artificial intelligence, specifically deep learning models. Their software was trained on millions of image frames, including a curated dataset of over 4,000,000 images representing 9,000 patients for Caption Interpretation. The AI continuously analyzes live B-mode image streams and compares them against learned patterns for standard cardiac views. The software can be integrated onto compatible ultrasound devices.
Physician Tip

For physicians, Caption Health's AI-powered ultrasound solutions, such as Caption AI, offer the ability to expand access to diagnostic-quality cardiac ultrasounds, even for clinicians without specialized sonography training. This can lead to earlier detection of heart conditions like heart failure, potentially preventing hospitalizations and improving patient outcomes. The real-time guidance and automated interpretation of ejection fraction can enhance confidence in image acquisition and provide quick, accurate assessments at the point of care, including in emergency rooms, ICUs, and even in-home settings. This technology can help standardize the quality of care and free up highly trained sonographers for more complex cases.

Caption Health's software can be integrated onto compatible ultrasound devices. Following its acquisition by GE HealthCare in 2023, Caption Guidance is being integrated into GE HealthCare's ultrasound systems, including the Venue Family point-of-care ultrasound systems and Vscan Air SL handheld ultrasound. This integration aims to further expand access to diagnostic care and the use of ultrasound in various care settings. Caption Health also partnered with Portamedic to offer in-home heart wellness assessments using the Caption AI platform.
