Midjourney Launches Medical Division to Build Full-Body Ultrasound Scanner in 60 Seconds

If you’ve ever had to wait weeks for an MRI appointment, only to spend over an hour lying perfectly still inside a noisy tube, the idea of a full-body scan completed in under a minute might sound almost too good to be true. That’s exactly what Midjourney — the company most people know for generating AI artwork from text prompts — is now claiming to offer. The company has announced a new healthcare division, Midjourney Medical, along with a prototype scanner it’s calling Ultrasonic CT, short for Fullbody Ultrasonic Computational Tomography.

It’s a striking pivot. One month you’re making pictures of cats in the style of Vermeer; the next you’re announcing ambitions to reshape global medical imaging. Whether the technology lives up to the billing is another matter entirely.

What Is the Ultrasonic CT Scanner, Exactly?

The device works by having a person stand on a platform and be slowly lowered through a ring packed with hundreds of thousands of ultrasound elements, all while submerged in water. The water isn’t incidental — it acts as a medium that helps ultrasound waves travel efficiently through the body. As the patient moves through the ring, the ultrasound emitters and receivers collect data from every angle, and algorithms then reconstruct that data into a three-dimensional image of the body.

Midjourney claims the system can produce a detailed 3D body map at sub-millimetre resolution in around 60 seconds. A standard full-body MRI, by comparison, typically takes 60 to 90 minutes in clinical practice, according to NHS England and standard radiology guidance. That’s a large difference, if the claims hold up.

The company describes the resulting images as MRI-like 3D visualisations, built not on magnetic resonance but on what it calls ultrasound-on-chip technology. And because ultrasound doesn’t use X-rays or ionising radiation, there’s no radiation dose involved — which, in principle, is a meaningful advantage over conventional CT scanning.

The Branding Has Already Raised Eyebrows

Not everyone is comfortable with the name. Calling the system “CT” is causing some confusion among imaging specialists, because CT — computed tomography — has for decades referred specifically to X-ray-based scanning. This device uses no X-rays in the slightest. Critics argue the “Ultrasonic CT” label could mislead patients and clinicians into assuming a level of equivalence with established imaging modalities that hasn’t yet been demonstrated.

Midjourney has also made some very large claims in its marketing materials. The company has suggested that widespread use of its scanner could prevent around 30% of deaths and cut healthcare costs by around 50%. These figures come entirely from Midjourney’s own statements and are not supported by independent epidemiological or health-economic research. No peer-reviewed clinical trials have validated the scanner’s diagnostic performance, and those projections should be treated with considerable caution.

No Regulatory Approval — Yet

This is the part that matters most right now. The Ultrasonic CT scanner does not have clearance from the US Food and Drug Administration, nor from any equivalent body, for diagnostic use. Midjourney has been clear that its initial commercial offering will focus on body-composition mapping — essentially a wellness service — rather than formal medical diagnosis. Think of it less as a hospital scan and more as an advanced health-tracking tool, at least for now.

The company’s first planned scanning location is a private “spa” facility in San Francisco, not a hospital. Midjourney has stated it intends to pursue FDA approval for diagnostic use after gathering clinical data, and plans to spend the next 12 months refining its algorithms and developing second-generation hardware. But none of that has happened yet.

Clinicians and imaging experts have raised legitimate questions about image quality compared with MRI and CT, the risk of false positives — where a scan flags something that turns out to be harmless — and the broader concern of over-screening otherwise healthy people. Ethicists have also flagged issues around data privacy, health inequalities, and whether early access will simply become another premium service available only to those who can afford it.

To be fair, Midjourney isn’t pretending otherwise at this stage. The company has positioned the current device as a prototype and a starting point, with broader ambitions — including a stated target of deploying around 50,000 scanners worldwide by 2031 — described as long-term goals rather than near-term commitments.

A Genuine Leap, or Overreach?

Supporters in the tech and AI community point to this as evidence that the computational expertise behind generative AI — processing vast amounts of data to reconstruct complex outputs — can translate meaningfully into medical imaging. There’s a logical thread there. Reconstructing a 3D body map from thousands of ultrasound data points is, at its core, a computational problem, and Midjourney has genuine strength in that area.

But the gap between a promising prototype and a clinically validated, regulatory-approved diagnostic tool is wide. Health systems like the NHS move carefully for good reason — patient safety depends on it.

What This Means for Kent Residents

There are no Midjourney Medical scanners in Kent, or anywhere in England, and the first announced location is a private facility in San Francisco. Before any version of this technology could be used in NHS Kent and Medway Integrated Care Board services, it would need to clear the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) and be assessed by relevant NHS bodies — a process that could take years. For now, Kent residents should treat this as an interesting development to watch rather than anything approaching an available option; if the technology does eventually reach the UK, it would most likely arrive first through private or research settings, not routine NHS care.
