Midjourney Medical

Midjourney Medical is a healthcare initiative announced in mid-June 2026 by Midjourney, the artificial intelligence research lab best known for its text-to-image generative AI service. The venture marks Midjourney's first move into physical hardware and into AI in healthcare, and is built around a whole-body imaging device that the company calls "Fullbody Ultrasonic Computational Tomography," shortened to "Ultrasonic CT," and a consumer wellness concept it calls the "Midjourney Spa." Midjourney says the system can scan a human body in roughly 60 seconds using sound waves rather than X-rays, and frames it as a long-term bet on accessible diagnostic imaging.^[1][2][3] The announcement drew wide attention both for the ambition of the claims and for the fact that Midjourney, a company with no prior medical track record, was the one making them. Medical-imaging specialists and journalists quickly noted that "Ultrasonic CT" is not an established imaging modality and that the headline performance figures had not been independently validated.^[4][5][6]

Background

Midjourney, led by founder and chief executive David Holz, rose to prominence after 2022 as one of the most widely used image-generation tools, producing pictures from natural-language prompts. The company has historically operated as a small, self-funded research lab rather than a venture-backed startup, and prior to 2026 had no products outside software image generation.^[2][3]

In a blog post titled "A New Era of Midjourney," Holz framed Midjourney Medical as part of a broader expansion of the company's mission beyond pictures and toward, in the company's words, giving people direct access to data about their own bodies. Coverage of the launch repeatedly stressed the gap between that ambition and the company's experience: as one report put it, Midjourney "makes pictures" and "has never built a physical product, never operated a medical device," and the scanner "has no regulatory clearance."^[5] The product was introduced at an event in San Francisco, with the public unveiling reported on June 17, 2026 and most coverage and partner commentary dated June 18, 2026.^[2][5][4]

Notably, Midjourney has stated that its own generative-AI image technology plays no role in forming the scanner's images. The image reconstruction is described as a computational tomography process driven by ultrasound physics rather than by the kind of generative model Midjourney is known for.^[1][4]

Ultrasonic CT technology

The device is marketed as "Ultrasonic CT," but despite the "CT" in the name it does not use X-rays or any ionizing radiation. Conventional computed tomography (CT) relies on X-rays; Midjourney's system instead uses ultrasound, meaning sound waves, together with water as a coupling medium, and the company says it involves no radiation and no strong magnetic fields.^[1][4]

According to Midjourney's description of the process, a person stands on a platform that gently lowers them into a shallow pool of water at roughly 2 inches (about 5 centimeters) per second. As the body descends, it passes through a ring containing on the order of half a million tiny elements, each described as roughly the size of a grain of sand, with each element able to act as both a small speaker and a small microphone. The ring fires sound waves through the body from many angles and records the returning signals, and software then reconstructs cross-sectional images of muscle, fat, bone, and organs.^[1][3][4] Butterfly Network's chief executive described the system as having "about half a million sensors scanning simultaneously and over two petaflops of processing power."^[7]

Midjourney makes several forward-looking performance claims for the system. The company says a full-body scan takes about 60 seconds, compared with roughly 60 to 90 minutes for a traditional MRI examination, and that it operates at "nearly a hundred times the speed" of MRI.^[5] Midjourney further claims the device will produce a three-dimensional map of the body with resolution resembling, and in the company's framing in some respects superior to, MRI.^[4][5] These are Midjourney's own characterizations, made at a product launch, and as of the announcement they had not been independently verified or published in peer-reviewed form.^[4][5][6]

Midjourney has said that the initial offering will provide body-composition maps rather than medical diagnosis, and that any diagnostic use would require regulatory clearance the company says it does not yet have and intends to pursue over time.^[4][5]

The Midjourney Spa

A central part of the concept is the "Midjourney Spa," a consumer, wellness-style setting in which the scanner would be installed. Midjourney has said it is building spas where people can find the machines and be scanned, presenting the 60-second scan as something as casual and routine as a trip to the spa rather than a clinical procedure. Some coverage of the launch described the experience in evocative terms, noting imagery of patients bathing in golden light during the scan.^[1][3]

The spa framing positions the product initially as a consumer wellness and body-composition service rather than a regulated diagnostic device, which is consistent with Midjourney's statement that the first offering will be body-composition maps rather than diagnosis.^[4][5] Critics have argued that this wellness positioning is also a way to begin operating before securing the regulatory clearances that diagnostic imaging would require.^[4][6]

Butterfly Network partnership

The scanner is built on a co-development and exclusive licensing agreement with Butterfly Network, Inc. (Nasdaq: BFLY), a publicly traded company known for handheld, semiconductor-based ultrasound devices. The collaboration runs through Butterfly Embedded, the company's Ultrasound-on-Chip licensing and co-development business, which was formerly known as Octiv.^[1][7]

Butterfly disclosed the terms in a Form 8-K filed with the U.S. Securities and Exchange Commission on November 17, 2025, and publicly commented on the venture on June 18, 2026, the day after Midjourney's unveiling. Butterfly said the current scanner prototype incorporates 40 Butterfly Ultrasound-on-Chip imaging modules per system, with future generations expected to use substantially more modules.^[1][7] Butterfly shares rose following the announcement.^[8]

According to Butterfly's filing and subsequent reporting, the five-year agreement provides for up to about $74 million in expected payments to Butterfly. The disclosed structure includes a one-time, non-recurring fee, an annual licensing fee payable quarterly, and additional payments tied to certain milestones, with Butterfly also eligible for revenue-sharing on Midjourney hardware that incorporates Butterfly chips and for payments on chip purchases.^[1][9]

Butterfly chief executive Joseph DeVivo described the partnership as "a potentially meaningful commercial opportunity for Butterfly" and said the company was "proud to support Midjourney's mission to democratize access to personal imaging data." DeVivo, framing the broader rationale, added that after decades in healthcare it was clear to him that the U.S. healthcare system "is still primarily designed to treat illness, not prevent it."^[1][7]

Roadmap and rollout

Midjourney has laid out an aggressive multi-year roadmap for Midjourney Medical, though the company has cautioned that the initial device is a first-generation prototype without regulatory clearance.^[4][5] The stated plan calls for refining the system and conducting research over roughly the following year, opening a first Midjourney Spa housing the scanners in San Francisco in 2027, expanding to additional cities and introducing a third-generation machine built on custom silicon for improved image quality in 2028, and scaling to a target of roughly 50,000 scanners worldwide by about 2031, described as a goal for "the next six years." Midjourney has also expressed an ambition to perform on the order of a billion full-body scans per month once such a fleet is in place.^[1][2][4]

These figures represent Midjourney's stated targets rather than confirmed deployments, and the company has acknowledged that diagnostic use would depend on obtaining regulatory clearance it does not yet hold.^[4][5]

Reception and skepticism

The announcement was met with a mix of excitement about the engineering demonstration and substantial skepticism from medical-imaging experts, radiologists, and journalists. A recurring theme in the coverage was that the demonstration was impressive but that the clinical, regulatory, and economic case remained largely unproven.^[4][6]

Several specific concerns were raised:

• "Ultrasonic CT" is not an established modality. Multiple outlets noted that the "Ultrasonic CT" label is Midjourney's own coinage and that despite the "CT" name the device uses ultrasound rather than X-rays. Ultrasound tomography of this kind is a research area rather than a routine clinical imaging standard, and reviewers emphasized that the technique had not been validated for whole-body diagnostic use.^[1][4]

• MRI-comparable and speed claims are unverified. Reporting stressed that the comparisons to MRI, including the "in some ways superior to MRI" framing and the "nearly a hundred times the speed" figure, were Midjourney's own statements made at a launch, "not independently verified findings." One report underscored the word "claimed," noting that Midjourney "has never built a physical product" and "never operated a medical device."^[5][6]

• No peer review and no FDA clearance. Commentators noted that no peer-reviewed paper had been published on the system's accuracy, that no radiologist outside Midjourney had evaluated the image quality, and that the device had no clearance from the U.S. Food and Drug Administration for diagnostic imaging. Midjourney itself said it would begin with body-composition maps rather than diagnosis and would pursue regulatory clearance over time.^[4][5][6]

• Gap between the 60-second claim and the prototype. At least one detailed explainer reported that the working prototype took on the order of 20 minutes per scan rather than 60 seconds, that roughly 12 people had been scanned to date, and that there was no AI in the imaging-reconstruction pipeline, contrasting this prototype reality with the 60-second headline figure.^[6]

• Overdiagnosis and incidental findings. Radiologists warned about the risk of "incidentalomas," incidental findings from screening otherwise healthy people that are usually benign but can trigger unnecessary follow-up testing, anxiety, and cost. Critics pointed to longstanding guidance, including from the American College of Radiology, cautioning against whole-body screening of asymptomatic individuals, a pattern previously seen with whole-body CT and MRI screening programs.^[6]

• Data privacy and governance. Privacy researchers flagged that a full-body scan is among the most sensitive forms of biometric data and noted that details such as the consent form and the data's legal status had not been published, raising questions about governance and handling of the resulting imaging data.^[6]

• Midjourney's prior AI-anatomy controversy. Some critics, including Baltimore neuroradiologist Francis Deng, MD, invoked Midjourney's track record with anatomy when expressing doubts about the venture. Deng pointed to a widely publicized 2024 incident in which AI-generated images, produced with Midjourney and depicting grossly inaccurate rat anatomy, appeared in a paper in a Frontiers journal before the paper was retracted within days, an episode that became a high-profile example of flawed AI imagery passing peer review.^[4]

Overall, reviewers generally agreed that independent, peer-reviewed validation and regulatory clearance would be necessary before the system could be used for clinical or screening purposes, and that the announcement, however striking, should be read as a statement of ambition rather than evidence of a validated medical device.^[4][6]
