A spa-ready body scanner that blurs the line between wellness and medicine
Midjourney’s full-body ultrasonic scanner is a new body scanner technology that uses sound waves to produce rapid, whole-body images in a spa-like setting, promising MRI-style detail in about 60 seconds but launching without FDA diagnostic clearance, which creates a regulatory gap for consumers weighing convenience against safety and privacy. That tension is the real story here. Midjourney, known for AI image generation, has launched Midjourney Medical and unveiled the Midjourney Scanner, a full-body ultrasound machine it says can image a person in about a minute. The company openly talks about something “as powerful as MRI, and as casual as a trip to the spa,” signaling a deliberate move to reframe medical imaging as lifestyle wellness rather than clinical care. That marketing choice matters: it lowers psychological friction while sidestepping the protections people usually expect in a hospital or clinic.
How Midjourney’s body scanner technology works—and why speed is not the only metric
The Midjourney Scanner uses sound, not radiation or magnets: you stand on a platform, descend into water at about two inches per second, and pass through a ring of underwater sensors that sends ultrasonic waves from many angles to build a 3D body map. The ring is made of roughly half a million squares, each about the size of a grain of sand, firing ultrasound and recording the ripples that bounce back. Midjourney’s target is a scan in under 60 seconds, compared with the 60 to 90 minutes a full-body MRI can take, and it claims images that “look a lot like today’s MRIs but at nearly a hundred times the speed.” For now, early reports put real scans closer to 20 minutes, and the performance claims rest on the company’s demonstrations, not independent trials. The hardware itself is built on Butterfly Network’s ultrasound-on-chip technology under a November 2025 licensing deal worth up to USD 74 million (approx. RM341.6 million) over five years.
Spa locations, wellness branding, and an FDA approval gap
Midjourney is not pitching this device only to hospitals. It plans Midjourney Spas, complete with hot tubs, saunas, cold plunges, and private scanning rooms, where people can get regular full-body scans as part of a wellness routine. The first spa is scheduled for San Francisco in 2027, backed by a roadmap that includes algorithm tuning, research trials, and second-generation hardware over the next 12 months, followed by a third-generation scanner with custom silicon in 2028. Critically, the device has no FDA clearance for diagnosis; the initial product is a “body composition map” of muscle, fat, bone, and organs, a use that does not need regulatory approval. Diagnostic capabilities, Midjourney concedes, would require FDA medical device approval, which it says it will pursue in stages and by submitting regular test results. Until that process is complete, consumers are being sold powerful medical-style imaging in an environment that lacks the usual clinical safeguards.
The hidden risks: over-testing, uncertain accuracy, and health data privacy
The biggest danger is not the ultrasound waves; it is what routine whole-body scans of healthy people tend to do: surface ambiguous findings that trigger more tests, more cost, and more anxiety, even though most of those findings never need treatment. Any system built around repeated full-body scans raises questions about data storage, consent, accuracy, false positives, medical oversight, and who can access the results. In a spa setting, people may treat the scanner like a wellness gadget and underestimate the impact of false alarms, misinterpretations, or the absence of a doctor in the loop. Health data privacy is especially fraught when an AI company is involved; before this becomes part of everyday health routines, Midjourney will need to prove the technology works, show how it handles sensitive data, and meet the medical rules that apply to diagnostic tools. Until then, the excitement around fast scans risks overshadowing the practical harms of unregulated medical imaging technology.
What consumers should do as AI companies push into medical hardware
Midjourney’s pivot shows how far AI firms are willing to move beyond software and into hardware that looks and feels medical but is sold through wellness channels. The company imagines 50,000 scanners worldwide and a billion scans a month by 2031—a scale at which any design or governance flaw becomes a public health issue, not a niche concern. Consumers should treat spa-based scans with the same skepticism they would bring to a new drug: ask whether the device has FDA diagnostic clearance, who reads the images, what happens to scan data, and how findings will be handled. Routine scanning might appeal to health-conscious people, but without clear evidence of benefit, strong privacy protections, and medical oversight, it risks becoming a high-tech worry machine. The core takeaway is simple: convenience is not a substitute for regulation. Until Midjourney proves safety, accuracy, and responsible handling of health data, the safest choice is to see its scanner as experimental—not essential.
