Midjourney Launches Bathtub Full-Body Scanner: Generates Submillimeter 3D Human Model in 60 Seconds

AI art company Midjourney announced the formation of Midjourney Medical in May 2025 and unveiled a full-body ultrasound scanner called Midjourney Scanner. The device integrates 500,000 micro-acoustic transducers into a bathtub, allowing users to soak in warm water for 60 seconds to complete a full-body scan, generating a 3D holographic human model with 0.5 mm precision, including blood vessels, bones, muscles, and real-time blood flow information. The scan is nearly 100 times faster than traditional MRI and radiation-free.

Technical Principles

• Hardware: The scanner consists of a ring array of approximately 500,000 micro-transducers, each functioning as both a speaker and a microphone, emitting millions of ultrasonic waves per second and recording echoes.
• Data Volume: Generates several terabytes of data per second, equivalent to 500 hours of high-definition video.
• Computing Power: Equipped with 21 servers, delivering 4 Petaflops of computing power, using Midjourney's diffusion model algorithm to reconstruct acoustic waveform data into high-definition human structures.
• AI Processing: Performs semantic segmentation on raw images, labeling anatomical structures such as rectus abdominis, blood vessels, and bones, ultimately stitching them into a full-body 3D map.

Deployment Roadmap

• 2027: The first Midjourney Spa flagship store opens in San Francisco, where users can complete scans while relaxing in baths or saunas, with results provided as body composition maps.
• 2028: Launch of the third-generation scanner with custom chips, improving imaging quality and speed.
• 2031 Goal: Deploy over 50,000 scanners globally, achieving 1 billion scans per month.
• Regulatory Strategy: Initially provide only body composition information, gradually seeking approval for higher-level diagnostic capabilities.

Impact and Controversy

• Medical Potential: Midjourney claims that widespread early imaging intervention could prevent 30% of global deaths and reduce healthcare costs by 50%.
• Industry Reaction: The news caused a stir in Silicon Valley, with Elon Musk liking the announcement. Some radiologists believe that if real-time physiological changes can be captured with high fidelity, it could revolutionize vascular and blood flow imaging.
• Controversies: The device has not yet received approval from regulatory bodies like the FDA, limiting its diagnostic capabilities; large-scale deployment raises concerns about privacy, data security, and ethics.
