In his workplace at the VA hospital in Seattle, Dr. Nadeem Zafar wanted to settle a debate.
Zafar is a pathologist, the type of physician that carries out scientific lab assessments on bodily fluids and tissues to diagnose situations like cancer. It’s a specialty that always operates behind the scenes, nevertheless it’s a vital spine of medical care.
Late final yr, Zafar’s colleague consulted with him a few prostate cancer case. It was clear that the affected person had cancer, however the two doctors disagreed about how extreme it was. Zafar believed the cancer was extra aggressive than his colleague did.
Zafar turned to his microscope – a canonically beloved instrument in pathology that the doctors depend on to help make their diagnoses. But the system isn’t any odd microscope. It’s an synthetic intelligence-powered microscope constructed by Google and the U.S. Department of Defense.
The pair ran the case via the particular microscope, and Zafar was proper. In seconds, the AI flagged the actual half of the tumor that Zafar believed was extra aggressive. After the machine backed him up, Zafar mentioned his colleague was satisfied.
“He had a smile on his face, and he agreed with that,” Zafar instructed CNBC in an interview. “This is the magnificence of this expertise, it is type of an arbitrator of types.”
The AI-powered instrument is named an Augmented Reality Microscope, or ARM, and Google and the Department of Defense have been quietly engaged on it for years. The expertise continues to be in its early days and is just not actively getting used to help diagnose sufferers but, however preliminary analysis is promising, and officers say it may show to be a great tool for pathologists with out quick access to a second opinion.
A brand new instrument for pathologists
Augmented Reality Microscope at Mitre

There are at present 13 ARMs in existence, and one is situated at a Mitre facility simply outdoors of Washington, D.C. Mitre is a nonprofit that works with authorities companies to sort out massive issues involving expertise. Researchers there are working with the ARM to determine the vulnerabilities that would trigger points for pathologists in a scientific setting.
At first look, the ARM appears to be like lots like a microscope that may very well be present in a highschool biology classroom. The system is beige with a big eyepiece and a tray for analyzing conventional glass slides, nevertheless it’s additionally linked to a boxy laptop tower that homes the AI fashions.
When a glass slide is ready and mounted below the microscope, the AI is in a position to define the place cancer is situated. The define seems as a shiny inexperienced line that pathologists can see via their eyepiece and on a separate monitor. The AI additionally signifies how unhealthy the cancer is, and generates a black and white warmth map on the monitor that exhibits the boundary of the cancer in a pixelated kind.
CNBC demoed the ARM with researchers at the Mitre facility in August.

Patrick Minot, a senior autonomous programs engineer at Mitre, mentioned since the AI is overlaid straight onto the microscope’s area of view, it would not interrupt the pathologists’ established workflow.
The simple utility is an intentional design selection. In latest years, pathologists have been contending with workforce shortages, identical to many other corners of well being care. But pathologists’ caseloads have additionally been mounting as the common inhabitants grows older.
It’s a harmful mixture for the specialty. If pathologists are stretched too skinny and miss one thing, it may well have severe penalties for sufferers.
Several organizations have been attempting to digitize pathologists’ workflows as a means to improve effectivity, however digital pathology comes with its personal host of challenges. Digitizing a single slide can require over a gigabyte of storage, so the infrastructure and prices related to large-scale knowledge assortment can balloon shortly. For many smaller well being programs, digitization is just not but price the trouble.
The ARM is just not meant to change digital pathology programs, however Minot mentioned it may well help well being organizations bypass the want for them. Pathologists have the choice to take display screen grabs of slides utilizing ARM’s software program, as an illustration, which are a lot cheaper to retailer.
The ARM will normally price well being programs between $90,000 to $100,000.
Minot added that the ARM ensures the bodily microscope, not simply a pc, stays an integral half of the pathologists’ course of. Many have warned him not to mess with their microscopes, he joked.
‘Big knowledge is what Silicon Valley does greatest’

Few perceive the challenges dealing with pathologists fairly like Dr. Niels Olson, the chief medical officer of the Defense Innovation Unit, or DIU, at the Department of Defense.
The DIU was created in 2015 as a means for the army to combine cutting-edge expertise developed by the business world. The group negotiates contracts with firms to allow them to collaborate and circumvent lengthy bureaucratic cling ups.
Olson is a pathologist, and earlier than starting his position at the DIU, he served in the U.S. Navy. In 2018, he was despatched to Guam, a U.S. island territory in Micronesia, the place he labored as the laboratory medical director and blood financial institution director in the Naval Hospital.
During his two years in Guam, Olson was one of two pathologists on the island, and the solely pathologist in the Naval Hospital. This meant he was usually making main selections and diagnoses on his personal.
“It’s not simply your job to say ‘This is cancer, it is this type of cancer.’ Part of the job is saying ‘It’s completely not cancer,’ and that may be nerve wracking if you’re alone,” Olson instructed CNBC in an interview. “I might have cherished to have an Augmented Reality Microscope in Guam, simply so there’d be someone, one thing else serving to.”
The ARM is supposed to function a second line of protection for pathologists, and Olson mentioned it could not change the doctors themselves. He added that the apparent preliminary use case for the microscope could be in smaller, distant labs, and it may additionally function a useful resource for pathology residents in coaching.
But Olson had dreamed up a instrument like the ARM lengthy earlier than his time in Guam. On Aug. 10, 2016, whereas working as a resident in the Naval Medical Center in San Diego, Olson determined to message a connection he had at Google. In the e mail, which was considered by CNBC, Olson described a tough concept of what a microscope like the ARM may very well be.
For some time, Olson mentioned he heard nothing. But months later, he was standing in a Google workplace building in Mountain View, California, crammed in a locked room that just a few folks at the firm had entry to. There, he watched as an early AI-powered microscope efficiently recognized cancer on a small set of slides he had introduced with him.
Olson mentioned the room was sweltering as a result of everybody inside was so “pumped.”
“I do not need to say it is fairly like seeing your child for the first time, nevertheless it was type of like, that is superior, that is gonna be a factor,” Olson mentioned.
Around the time he was despatched to Guam, a product supervisor at the DIU got here throughout Olson’s analysis. The pair wrote an article collectively in 2019 about how the Department of Defense and Silicon Valley may work collectively to leverage AI. They mentioned there are tens of millions of sufferers enrolled in the federal authorities’s well being care programs, which suggests it boasts “the most complete healthcare dataset in the world.” That knowledge has apparent business use.
“Big knowledge is what Silicon Valley does greatest, and the potential for spillover into civilian healthcare programs is huge,” they wrote.
Shortly thereafter, the DIU started searching for business companions to help construct and check the ARM. The group picked the optical expertise firm Jenoptik to deal with the {hardware}, and after evaluating 39 firms, it chosen Google to develop the software program.
Aashima Gupta, world director of well being care technique and options at Google Cloud, mentioned the firm has since launched 4 algorithms for the ARM which may determine breast cancer, cervical cancer, prostate cancer and mitosis. The AI fashions are educated on knowledge from the DIU, and Gupta mentioned neither Google staff nor Google infrastructure have entry to it.
“It’s encrypted all the means,” Gupta instructed CNBC in an interview. “From how the knowledge is collected, how it’s saved and how it’s analyzed, and something in between.”
A ‘enormous’ quantity of testing to be accomplished
With the {hardware} and the software program so as, the DIU has been finishing up preliminary analysis to check the ARM’s efficacy.
In the fall of 2022, the group revealed a peer-reviewed paper in the Journal of Pathology Informatics. The paper discovered that the breast cancer AI algorithm carried out moderately effectively throughout a big area of samples, however there are caveats, mentioned David Jin, the lead writer on the paper and the deputy director for AI evaluation at the Department of Defense’s Chief Digital and Artificial Intelligence Office.
The paper particularly examined how effectively the AI carried out when detecting breast cancer metastasis in lymph nodes, and Jin mentioned it did higher on sure sorts of cells than others. He mentioned the research is promising, however there’s nonetheless a “enormous” quantity of rigorous testing to be accomplished earlier than it may well help pathologists with actual affected person care.
“Something like this has an excessive potential for profit, but additionally there’s lots of dangers,” as it could change how cancer analysis is finished, Jin instructed CNBC in an interview.
Olson, who returned from Guam and started working at the DIU in 2020, can be listed as an writer on the paper. He mentioned unbiased assessments of the different three fashions, for prostate cancer, mitosis and cervical cancer, haven’t been carried out at the DIU but.
Research with the ARM is ongoing, and the DIU can be soliciting suggestions from organizations like Mitre and well being programs like Veterans Affairs. There is figure to be accomplished, however since the DIU has validated the preliminary idea, the group is starting to take into consideration how to scale the expertise and collaborate with regulators.
The DIU negotiated agreements with Google and Jenoptik that may permit the expertise to be distributed via the army and commercially. The DIU is hoping to make the ARM accessible to all authorities customers via the General Services Administration web site someday this fall.
Zafar of VA Puget Sound mentioned that in the end, although the ARM will definitely support pathologists, the common public will profit most from the expertise. He mentioned the ARM’s accuracy, pace and price effectiveness will all contribute to higher care.
“AI is right here, and it is going to maintain creating,” Zafar mentioned. “The level is just not to be afraid of these applied sciences, however to triage them to the greatest use for our medical and well being care wants.”
