Midjourney Medical: What We Know So Far About the AI Company’s Full-Body Ultrasound Scanner

Midjourney, the company best known for its AI image generator, announced a new division called Midjourney Medical yesterday. Along with it, they showed an early prototype of a full-body scanner they’re calling Ultrasonic CT.

The scanner is designed to create detailed 3D images of the body using ultrasound while the person is in water. Midjourney says a scan should take about 60 seconds and aims for image quality comparable to MRI in many areas, without radiation or strong magnetic fields.

It’s the shorter video they released with the announcement. It gives readers a quick visual sense of what they’re proposing.

You can read the full announcement on their site here.

They’ve also set up a dedicated page.

The core idea is a new form of whole-body imaging they’re referring to as Ultrasonic CT. A person steps onto a platform that lowers them through a ring of ultrasonic sensors in water. The system captures data from multiple angles and reconstructs it into 3D maps of muscle, fat, bone, and organs. They’re using AI for the reconstruction and segmentation steps.

Early examples are already up on their scan gallery.

These show reconstructed slices, AI-labeled segmentations, and some comparisons with conventional MRI.

Midjourney released a longer technical video that walks through the prototype in more detail. If you want to give readers a deeper look, embed it in this section:

They’ve said the system uses a large number of tiny ultrasonic transducers arranged in a ring. Sound waves pass through the body, and the changes in those waves are used to build the image. The company has described the data volume during a scan as very high, with heavy processing involved in turning the raw acoustic data into usable 3D images.

So far, only a small number of people have been scanned with the current prototype. They’re also working with Butterfly Network on the ultrasound hardware side.

Midjourney is framing the scanner as part of a broader wellness experience rather than a traditional clinical setting. The first location, called the Midjourney Spa, is planned for Union Square in San Francisco and is scheduled to open at the end of 2027. It will include hot tubs, saunas, and cold plunges alongside the scanners.

The stated goal is to make advanced body imaging feel more like a routine, low-friction activity that people might do more regularly to track changes over time.

In the announcement, Midjourney laid out big targets: deploying around 50,000 scanners worldwide over the next six years and building capacity for roughly a billion full-body scans per month. They plan to start with body composition mapping and expand through additional regulatory steps.

They’re currently hiring for engineering and operations roles to support the effort.

The announcement has sparked a lot of discussion online. Elon Musk even commented on the announcement. Some people are interested in the technical approach and the potential for faster, more accessible imaging. Others — particularly people who work in radiology — have pointed out real-world challenges with ultrasound imaging in certain parts of the body and the need for more clinical validation and data.

Midjourney has noted that the current images come from early prototype work and that there’s still significant room to improve.

This is still very early. The prototype exists, some images and videos have been shared, and the high-level vision is public. What happens from here will depend on how the technology performs in further testing, how regulatory and clinical validation goes, and whether they can execute on the experience and scale they’ve described.

For now, the main sources are the announcement itself and the early gallery on their site. Both are worth reviewing directly if you want the raw details.
