Midjourney has announced a medical imaging venture called Midjourney Medical, centered on a full-body ultrasound scanner that submerges users in water and produces MRI-quality 3D images in under 60 seconds. The technology uses half a million tiny sensor elements to send and receive ultrasonic waves, reconstructing detailed body composition maps through massive parallel computing. Plans include opening the first Midjourney Spa in San Francisco in 2027, scaling to over 50,000 scanners worldwide by 2031, with the stated ambition of preventing 30% of global deaths and halving healthcare costs through early detection.
