Midjourney, the community-backed AI lab known for its image generator, has made an unexpected leap into healthcare hardware, unveiling a full-body ultrasound scanner it calls "Ultrasonic CT." The system promises MRI-quality, whole-body imaging in about 60 seconds — with no radiation and no magnets, just sound and water.
How the scanner works
A person steps onto a platform and is gently lowered, at roughly five centimeters per second, into a shallow pool of warm water. As they descend, they pass through a ring built from about half a million tiny elements, each the size of a grain of sand and each capable of acting as both a microscopic speaker and microphone. The elements fire ultrasonic waves through the body from every angle and listen to how those waves change as they cross boundaries between water, skin, fat, muscle and bone. A cluster of thousands of computers then reconstructs the returning signals into cross-sectional images, producing terabytes of data per second.
The Midjourney Spa
Rather than selling machines to hospitals, Midjourney plans to house the scanners inside wellness venues it calls Midjourney Spas, complete with hot tubs, saunas and cold plunges. The first is slated to open in San Francisco at the end of 2027. The pitch is that scanning becomes a casual, even pleasant, routine — "the scans are a side-effect," the company says — while users quietly build a longitudinal library of body-composition data they can track over time and share with doctors or AI health assistants.
Regulation, partners and roadmap
Midjourney is starting with non-diagnostic body-composition maps and says it will submit regular test results to the U.S. Food and Drug Administration as it seeks expanded, diagnostic capabilities. The effort builds on a co-development and exclusive licensing agreement with ultrasound pioneer Butterfly Network, signed in late 2025. A third-generation scanner with fully custom silicon is planned for 2028, and the lab's stated ambition is a fleet of more than 50,000 scanners worldwide by 2031, capable of a billion scans a month.
Part of a broader imaging push
The announcement lands as AI reshapes medical imaging across the board, from Philips' FDA-cleared auto-measurement ultrasound to Aidoc's breakthrough radiology foundation model and research such as MIT's ultrasound wristband for robotic control. Whether a self-funded image lab can clear the regulatory and clinical bar for whole-body diagnostics remains the open question — but Midjourney is betting that cheap, fast, frequent imaging could fundamentally change how people relate to their own health.
