Midjourney’s AI-Powered Ultrasound Scanner: A "Spa Experience" That Could Redefine Preventative Health
Midjourney, best known for its AI-generated images, is entering the medical imaging space with a full-body ultrasound scanner designed for speed, accessibility, and—eventually—FDA clearance. Dubbed the Midjourney Scanner, the device blends ultrasound technology with AI processing to create detailed 3D body composition maps in under a minute. The company plans to launch a "spa" in San Francisco by 2027, where visitors can scan their bodies alongside gyms, saunas, and cold plunges. But experts warn that while the concept is ambitious, regulatory hurdles and technical limitations remain significant.
What Is the Midjourney Scanner, and How Does It Work?
The Midjourney Scanner is an ultrasound-based device developed in partnership with Butterfly Network, a company specializing in compact, high-resolution ultrasound technology. Unlike traditional MRI or CT scans, which use radiation or powerful magnets, the scanner relies on 40 ultrasound-on-chip modules arranged in a ring to capture vertical slices of the body.
Here’s how it works:
- A user steps onto a platform that lowers them into a shallow pool of water.
- The ring of sensors emits ultrasonic waves from every angle, creating a 3D map of internal structures—muscle, fat, bone, and organs—in about 60 seconds.
- The data is processed using two petaflops of computing power (equivalent to high-end AI servers) to generate images comparable to MRI scans in some cases, according to David Holz, Midjourney’s CEO.
"We’re aiming for image quality comparable to MRI in many ways, but without the radiation, magnets, or long wait times," Holz told attendees at a recent demo. "The goal is to make preventative health as routine as checking your phone."
The scanner’s initial focus is on body composition analysis—tracking muscle, fat, and organ health—rather than diagnostic imaging, which requires stricter FDA clearance. Midjourney Medical, the division overseeing the project, has not yet applied for full FDA approval but claims the technology could eventually surpass MRI in speed and accessibility.
Why Is Midjourney Entering Medical Imaging?
Holz has framed the scanner as a natural extension of Midjourney’s AI expertise, though the company’s primary revenue still comes from its AI image generation tool. The scanner’s development appears to be driven by three key factors:
- Unused AI Infrastructure: Midjourney’s existing AI hardware could be repurposed for medical imaging processing, reducing costs.
- Consumer Health Trends: Demand for at-home health monitoring (e.g., wearables like Whoop or Oura Rings) has surged, with users increasingly tracking biomarkers like muscle recovery and fat loss.
- Regulatory Arbitrage: By starting with non-diagnostic body composition scans, Midjourney avoids the lengthy FDA approval process required for diagnostic tools. "We’re working within the regulatory gray area for now," Holz said, "but the long-term vision is to get to a place where people can scan themselves daily—like a fitness tracker, but for the inside of your body."
The company’s job listings confirm this strategy, describing the project as an effort to "bring safe, fast, and high-fidelity preventative scanning to billions via a magical spa experience."
How Does This Compare to Existing Medical Imaging?
The Midjourney Scanner isn’t the first attempt at portable, AI-enhanced medical imaging, but it stands out in three ways:
| Feature | Midjourney Scanner | Traditional MRI/CT | Portable Ultrasound (e.g., Butterfly IQ+) |
|---|---|---|---|
| Speed | ~60 seconds | 30–60 minutes | 5–15 minutes |
| Cost (Estimated) | ~$5,000–$10,000 per unit (bulk pricing) | $1M–$2M+ per MRI machine | $20,000–$50,000 per unit |
| FDA Clearance Needed | None (for body composition only) | Full clearance for diagnostics | Partial (varies by use case) |
| Image Quality | "Comparable to MRI in many ways" (Holz) | Gold standard for diagnostics | Lower resolution, limited depth |
| Accessibility | "Spa-like" experience (gyms, saunas) | Hospital/clinic-bound | Clinician-operated, not consumer-friendly |
Key Takeaway: The Midjourney Scanner prioritizes speed, cost, and consumer convenience over diagnostic precision. While it may not replace MRIs for cancer screening or complex diagnoses, it could fill a gap for wellness tracking, sports performance, and early-stage health monitoring—if regulatory and technical challenges are overcome.
What Are the Biggest Challenges?
Despite the hype, the scanner faces three major hurdles:
-
Regulatory Uncertainty
- The FDA has not yet classified the device, and body composition scans (even non-diagnostic) could trigger scrutiny if marketed as health-related. "The line between wellness and diagnostics is blurry," says Dr. Daniel B. Hier DBH, a radiology expert at Harvard Medical School. "If this becomes a tool for tracking organ health, it will need full clearance."
-
Image Accuracy vs. MRI/CT
I Interviewed the Most Creative Man Alive: David Holz (CEO of Midjourney) - While Holz claims "MRI-like quality," ultrasound has long been limited by artifacts and lower resolution compared to MRI or CT. A 2023 study in Radiology found that even advanced ultrasound-on-chip systems struggle with deep tissue imaging and bone density precision—critical for detecting early-stage diseases.
-
Data Privacy and Security
- Midjourney has pledged to "take data privacy seriously," but the company has no track record in healthcare data protection. With AI processing two petaflops of data per scan, storing and securing these records could become a liability. "This is not just about the hardware," warns Kara Swisher, technology journalist. "It’s about who owns the data—and whether users will trust Midjourney with their internal scans."
What Happens Next? The 2027 Spa Launch and Beyond
Midjourney plans to open its first "Midjourney Spa" in San Francisco’s Union Square by late 2027, featuring:
- 10 scanner units (each capable of processing 50+ scans per hour).
- Gyms, saunas, and cold plunges to complement the scanning experience.
- Optional AI-powered health analytics, where users can share scan data with doctors or third-party apps.
"We’re not just selling a machine," Holz said. "We’re selling a lifestyle—one where you can track your body’s changes in real time, like a fitness app for your insides."
But the real test will be whether the technology lives up to its promises:
- By 2028, will the FDA allow diagnostic use cases (e.g., liver fat detection, muscle recovery tracking)?
- By 2030, could this become a consumer health standard, like smartwatches today?
- Will insurers cover it? If the scans are marketed as preventative care, some plans may reimburse—but only if accuracy is proven.
FAQ: What You Need to Know About the Midjourney Scanner
Q: Is this scanner safe?
A: Yes, but with caveats. Ultrasound uses no radiation, unlike CT or X-ray, and avoids the strong magnetic fields of MRI. However, long-term safety data (e.g., repeated daily scans) hasn’t been established. "We’re in uncharted territory," says Dr. Hier. "The risk isn’t immediate, but we don’t know the cumulative effects."
Q: How much will it cost?
A: Midjourney hasn’t disclosed pricing, but industry estimates suggest:
- Consumer spa access: $100–$200 per scan (similar to high-end wellness centers).
- Home/clinical units: $50,000–$100,000 (if scaled for bulk sales).
Q: Can it replace an MRI?
A: No—not yet. While Holz compares it to MRI, ultrasound lacks the depth and clarity for diagnosing conditions like tumors or neurological issues. "This is a tool for wellness, not diagnostics," says Butterfly Network’s CEO, Jonathan Rothberg. "Think of it like a Fitbit for your organs."
Q: Will my data be private?
A: Midjourney claims to prioritize privacy, but no details on encryption or third-party sharing have been released. Users should assume data will be monetized—either through partnerships with insurers, fitness apps, or AI health tools.
Q: When will it be available outside the spa?
A: Not soon. The 2027 spa launch is the first step. If successful, Midjourney may explore clinical partnerships by 2029, but home units are unlikely before 2030 due to regulatory and technical hurdles.
The Bigger Picture: Is This the Future of Health Tech?
Midjourney’s foray into medical imaging reflects a broader trend: tech companies are betting big on consumer health monitoring, blending AI, hardware, and wellness culture. But success depends on three critical factors:
- Can it deliver on accuracy? If the scans prove less reliable than claimed, adoption will stall.
- Will regulators allow it? The FDA’s stance on AI-powered ultrasound will determine whether this stays a "spa gimmick" or becomes a legitimate health tool.
- Will people pay for it? For now, wealthy biohackers and athletes may be early adopters—but mass-market appeal requires proven health benefits.
"This is less about revolutionizing medicine and more about creating a new kind of wellness experience," says Jane M. Orient, executive director of the Association of American Physicians and Surgeons. "The question is whether people will treat it like a luxury or a necessity."
For now, the Midjourney Scanner remains a high-risk, high-reward experiment—one that could either disrupt preventative health or become a footnote in the history of overhyped tech.
