Midjourney released a nearly 20-minute behind-the-scenes video of its medical ultrasound scanner on July 3, 2026, offering the first extended look at hardware the AI image startup hopes to place in spas and, eventually, medicine. The tour, hosted by tech YouTuber and Midjourney engineer Marcin Plaza, shows the physical build in detail but declines to answer the imaging questions experts raised when the project was first announced. The scanner will ship as a wellness product for body composition, not as a diagnostic device.
Plaza describes the machine plainly: scores of ultrasound probes "hacked apart and slapped on a glorified hot tub with an elevator in it," wired to off-the-shelf computers and Raspberry Pis. The dunk-tank design has a person submerge while an array of probes captures imagery, which Midjourney intends to process into detailed, radiation-free scans. The video walks through the team building the rig, the tank itself, and sample scans of an imaging phantom used to validate structural separation under controlled conditions.
What the video does not do is engage the physics. Experts who spoke to reporters after Midjourney first unveiled the project said the company had not shown it could overcome well-established limits of ultrasound, a technology that has been in clinical use for decades. Resolution, depth penetration, and reconstruction artifacts are not problems a larger tank of probes automatically solves. The video shows hardware, not benchmarks.
Key facts
- 01Midjourney published a nearly 20-minute behind-the-scenes video of its dunk-tank ultrasound scanner on July 3, 2026.
- 02The rig is built from ultrasound probes attached to a water tank, connected to off-the-shelf computers and Raspberry Pis.
- 03The device will launch as a wellness product for body composition, sidestepping FDA clearance and clinical trials.
- 04Head of medical Tom Calloway said the wellness framing lets Midjourney 'speedrun' to market once testing is complete.
- 05CEO David Holz cited the company's lack of investors as the reason it can pursue the scanner: 'No one can tell me not to do it.'
Tom Calloway, Midjourney's head of medical, said the wellness framing would let the company "speedrun" and open once testing is complete. A body-composition product does not require FDA clearance or clinical trials, both of which would push a launch out by years and force Midjourney to publish performance data. Calloway nonetheless leaned on medical language throughout the video, floating what physicians might do with frequent scans of a patient over time.
“I don't think there's anything to really clarify”— Tom Calloway, Midjourney head of medical
Asked about the mixed messaging, Calloway said he did not see a problem to address and promised frequent blog updates as the project progresses. That posture — medical ambition, wellness paperwork — is the tension the video does not resolve. Regulators tend to notice when a company markets a wellness device using clinical vocabulary, and body-composition scanning in spas is a much narrower claim than the imaging revolution Midjourney has hinted at publicly.
CEO David Holz framed the freedom to build the scanner as a direct consequence of Midjourney's ownership structure. The company has taken no outside investment, which Holz said gives him unilateral authority over what the company pursues. There is no board pressuring him to focus on the core image-generation business, and no VC syndicate to explain a hardware detour to.

That independence is a real advantage in a field where most AI companies now answer to investors expecting revenue growth from core model products. It also means there is no external check on whether the scanner effort is a sound use of the company's resources or whether the imaging claims stand up. Midjourney has not disclosed how much it has spent on the medical project or how large the team is.
The behind-the-scenes format itself is worth noting. Rather than publishing a technical paper, a benchmark against existing ultrasound systems, or a peer-reviewed validation study, Midjourney chose a YouTube walkthrough produced by one of its own engineers. That is a marketing artifact, not evidence. It lands well with the audience that follows Midjourney for its image models and less well with clinicians who will eventually decide whether any of this is useful in a medical setting.
For now, the scanner remains a curiosity: a well-funded image-generation company building a physical imaging device with off-the-shelf components and no published performance data. The wellness launch path lets Midjourney get the product into the market without regulatory friction, and the spa channel gives it a customer base that will pay for the experience regardless of clinical utility. Whether the images ever prove diagnostically meaningful is a separate question the company has not yet tried to answer.
The interesting business question is what Midjourney is actually building toward. If the endgame is a spa product, the medical framing is over-engineered marketing. If the endgame is a diagnostic device, the wellness launch is a way to accumulate scan data and refine the pipeline before facing regulators — a strategy that has worked for consumer health hardware before, and one that requires the imaging to eventually deliver. Either path is defensible; the company just has not said which one it is on, and its willingness to sit in that ambiguity is either strategic patience or a tell that the underlying imaging results are not yet where the pitch suggests.
