Midjourney shows off ultrasound scanner, but proof it works remains scarce

What happened

Midjourney, the AI image-generation startup, released a behind-the-scenes video of its ultrasound scanner—described as ultrasound probes connected to off-the-shelf computers and Raspberry Pis in a modified hot tub. The nearly 20-minute tour, led by engineer Marcin Plaza, showed the hardware and team but largely sidestepped physics and imaging questions that experts raised when the project was first announced.

Why it matters

Experts told The Verge that Midjourney has shown little evidence it can overcome the well-known limits of ultrasound or deliver the detailed images at the scale and speed it promises. The company is positioning the scanner as a wellness product focused on body composition rather than a diagnostic medical device, which allows it to sidestep FDA clearance and clinical trials—but the video still uses medical language, suggesting physicians could benefit from frequent scans over time. This approach may appeal to investors or early adopters, but the lack of independent validation leaves open questions about real-world performance.

What to watch

Midjourney plans to deploy the scanner in spas once testing is complete. CEO David Holz said the company's lack of investors gives it freedom to pursue the project without outside pressure. The company has promised frequent blog updates on progress.
