Midjourney, the AI company known for viral images like a Balenciaga-clad Pope, is launching a new division called Midjourney Medical, featuring a full-body scanner and a spa in San Francisco. The company says its ultrasound-based scanner is nearly 100x faster than a typical MRI and can build a complete 3D map of the body. Users step into a shallow pool and stand on a platform that slowly lowers through a ring of underwater sensors, which send ultrasonic sound waves through the body from every angle. Midjourney plans to install its scanners into the hot tubs, saunas, and cold plunges in its spa, which it says will open next year and allow for 24/7 access. The company aims to have a fleet of 50k scanners worldwide by 2031, generating up to 1B scans a month. However, the article notes potential pitfalls of full-body scans, including false positives, unnecessary anxiety, and extra costs, and that science communicator Hank Green cautions against comparing Midjourney’s scanner to MRI tech.
