Midjourney, the AI image generator known for transforming text prompts into stunning visuals, has taken a surprising leap into the world of medical imaging. During a livestreamed event, CEO David Holz unveiled the company's first hardware product: a full-body ultrasound scanner. Dubbed the Midjourney Scanner, this device uses a ring of sensors to capture vertical slices of the human body, revealing the composition of muscle, fat, bone, and organs. Holz envisions a future where people can be scanned daily, gaining insights into how their bodies change with diet, exercise, and lifestyle.
The scanner is the result of a partnership with Butterfly Network, a company specializing in ultrasound-on-chip technology. Each system integrates 40 Butterfly Ultrasound-on-Chip imaging modules, which work together to generate detailed 3D images. The scanning process begins with a user stepping onto a platform that descends into a pool of water. As the body passes through a ring of thousands of transducers, ultrasonic waves are emitted from every angle. These waves pass through the body, and the device records how they ripple and reflect. The entire scan takes about 60 seconds, and approximately a dozen people have already been scanned during testing.
Holz explained that the device uses two petaflops of processing power to analyze the data. The result is a high-resolution image that can be segmented using AI to highlight different tissues. In a demonstration, the company showed an AI overlay on a black-and-white ultrasound scan, distinguishing between muscle, fat, bone, and organs with remarkable clarity. While the image quality is not yet equivalent to an MRI, Holz believes the scanner "aims for image quality comparable to MRI in many ways" – without the need for powerful magnets, radiation, or the lengthy and often claustrophobic experience of an MRI scan.
From Cat Pictures to Medical Diagnostics
Midjourney's pivot into hardware might seem abrupt, but it reflects CEO David Holz's long-standing interest in measuring and understanding the human body. "I'm not the most measured man on Earth yet, you know, but maybe I want to have that daily measurable information," he said during the reveal. The company's job listings describe the goal as trying to "build and launch the world's first full-body ultrasound CT scanner, ultimately bringing safe, fast, and high fidelity preventative scanning to billions via a magical spa experience."
The scanner is not yet approved for diagnostic medical use. Midjourney Medical – the division behind the project – is initially focusing on "body composition maps" that do not require FDA clearance. These maps provide information about the distribution of muscle, fat, and bone, which can be useful for fitness enthusiasts, athletes, or anyone interested in tracking changes over time. Holz noted that the company plans to seek FDA clearances for specific medical applications in the future, but for now, the device is positioned as a wellness tool rather than a diagnostic one.
The Midjourney Spa Experience
To bring the scanner to the public, Midjourney is planning to open a spa in San Francisco's Union Square before the end of 2027. The Midjourney Spa will feature 10 scanning rooms, each equipped with a hot tub-like pool where visitors will descend into water to be scanned. The spa will also include a gym, saunas, and cold plunges, creating a holistic wellness environment. The scanning process itself is described as immersive: "It starts by stepping into a shallow pool of golden light. You then begin to descend into the water. Your body passes through a ring of underwater sensors, each acting like a dolphin, using its echolocation."
Holz hopes that the spa will attract people who want to understand their bodies better. The "library of scans" created by users can be shared with doctors, AI health tools, or others, with the company promising robust data privacy policies. "We take data privacy seriously — more details on our data policies will come as we get closer to launch," the company stated. The spa concept aligns with Midjourney's broader ambition to create experiences that blend technology, aesthetics, and personal well-being.
Ultrasound Technology with a Dolphin's Touch
The core technology behind the scanner is ultrasound, but on a scale never seen before in a consumer or spa context. Ultrasound uses high-frequency sound waves to create images of the inside of the body. The Midjourney Scanner amplifies this concept by deploying a ring of 40 sensor modules, each acting like a dolphin's echolocation. The sensors send ultrasonic waves through the body from every angle, and by capturing enough data points, the system constructs a three-dimensional image. This approach is fundamentally different from traditional handheld ultrasound probes, which require a technician to move the device across the body.
Butterfly Network's ultrasound-on-chip technology makes the system compact and scalable. Each chip is a miniature ultrasound transducer that can be arrayed in a ring. The partnership leverages Butterfly's expertise in solid-state ultrasound, which has been used in portable devices for point-of-care diagnostics. Holz emphasized that the scanner is safe, using no ionizing radiation and relying only on sound waves. The company claims that with enough processing power and data, the scanner could eventually become "superior to even MRI machines" for certain applications.
AI and the Future of Personal Health
Midjourney's background in AI image generation plays a role in the scanner's capabilities. The company uses machine learning algorithms to segment and enhance the ultrasound images, creating detailed maps of internal structures. The AI can isolate specific organs, measure fat layers, and track changes over time. While the current focus is on body composition, the same technology could be applied to other areas, such as detecting abnormalities or monitoring chronic conditions – provided regulatory approvals are obtained.
Holz envisions a future where people can scan themselves regularly, building a personal health database. "You could do this once a year or every single day," he said. The data could then be fed into AI health tools that provide personalized recommendations for diet, exercise, or medical interventions. This vision aligns with the broader trend of consumer health monitoring, from smartwatches to continuous glucose monitors, but adds a new dimension: deep internal imaging without the cost or inconvenience of hospital-based scans.
Regulatory Hurdles and Ethical Considerations
Bringing a full-body ultrasound scanner to market is not without challenges. The US Food and Drug Administration (FDA) classifies medical devices based on risk. For diagnostic imaging, the scanner would need to undergo rigorous clinical trials to demonstrate safety and efficacy. Midjourney Medical is initially avoiding this by marketing the device for body composition analysis, which is considered a wellness application rather than a medical one. However, as the company adds more features – such as organ-specific analysis or detection of anomalies – it will inevitably face regulatory scrutiny.
Holz acknowledged this during the livestream, suggesting that the FDA might need to create a new class of devices for "weird" things and allow people to "just try to get as much data as we can." This comment hints at a libertarian approach to health data, where individuals have the freedom to explore their own bodies without waiting for regulatory approval. However, privacy experts caution that such intimate data could be misused if not properly secured, and the company's promise of forthcoming data policies will be critical to building trust.
Another consideration is the accessibility of the spa. The scanner and spa experience are likely to be premium services, potentially limiting access to wealthy individuals. Holz did not disclose pricing, but the cost of developing and manufacturing 40 sensors per system, plus the spa real estate, suggests a significant investment. The company may need to find a business model that balances exclusivity with its stated goal of bringing preventative scanning to billions.
Despite these challenges, the Midjourney Scanner represents a bold step into a new domain for the AI company. It leverages existing technologies – ultrasound, AI segmentation, and spa aesthetics – to create a unique product. Whether it becomes a hit among wellness enthusiasts or a stepping stone to medical devices remains to be seen. For now, Midjourney is focused on building the first spa and perfecting the scanning experience. The company has already demonstrated the device on a handful of volunteers, and Holz offered to scan the hands of attendees at the launch event, giving a glimpse of what the future might hold.
The intersection of AI, health, and luxury is a rapidly evolving space. Companies like Apple, with its health-tracking wearables, and startups like Forward Health have already made inroads. Midjourney's approach – combining a scanner with a spa experience – is distinctive and reflects CEO David Holz's vision of making health measurement both enjoyable and informative. The company's journey from generating cat images to full-body ultrasound scans is a testament to its ambition and willingness to explore uncharted territory. As the Midjourney Spa prepares to open its doors in San Francisco, the world will watch to see if this bold experiment can transform how we understand our own bodies.
