Midjourney, the AI research lab known for its image generation technology, has announced Midjourney Medical – a new division building what it calls “Ultrasonic CT,” a full-body imaging system that uses ultrasonic sound waves and water to produce MRI-comparable scans in as little as 60 seconds, with no radiation and no magnetic fields.
The system works by lowering a person into a shallow pool of water through a ring containing half a million tiny ultrasonic elements that each act as both speaker and microphone, generating terabytes of data per second. AI then reconstructs a detailed 3D map of the body down to a fraction of a millimeter.
The first location will be a health spa in San Francisco opening in late 2027, combining hot tubs, saunas, and cold plunges with 10 scanners that Midjourney claims could perform more body scans per year than all MRI scanners on Earth combined. The company’s goal is 50,000 scanners worldwide by 2031 with capacity for a billion scans per month.
Midjourney, which has no outside investors and is funded entirely by its community, says it will start with body composition maps and progressively seek FDA approval for additional diagnostic capabilities. The company estimates that with enough early imaging, the world could avoid 30% of all deaths and 50% of all healthcare costs.
If the technology delivers on its promise – accessible, affordable, radiation-free full-body imaging as casual as a spa visit – the implications for women’s health screening are significant: From earlier breast cancer detection and reproductive organ imaging to tracking the cardiovascular, bone density, and body composition changes that accompany menopause.
