Perimeter Medical Imaging AI Giving surgeons clarity on
margins to act in the moment
and close with confidence Our goal is to improve patient outcomes and lower health care costs. The U.S.

Perimeter Medical Imaging AI is a pioneering medical technology company driven to transform cancer surgery with ultra-high resolution, real-time, advanced imaging tools that address unmet medical needs. Cancer is a global challenge, and we envision a world where patients no longer experience the costly emotional and physical trauma of being called back for a second surgery due to cancer left behind. A Toronto, Canada-based company established in 2013, with U.S. headquarters in Dallas, Texas, our proprietary technology allows surgeons to make more informed decisions during the surgical procedure. Until now, current technologies in the OR have not had the image resolution to identify microscopic features of excised tissues and shaved margins at the point-of-care. Our new OCT technology gives them real-time information vs. waiting several days for pathology reports. Perimeter S-Series OCT (Optical Coherence Tomography) is a groundbreaking medical imaging system that provides cross-sectional, real-time margin visualization of excised tissue specimens. It uses ultra-high-resolution OCT technology, developed out of MIT in 1991, an established imaging technology used in ophthalmology, cardiology and dermatology. Analogous to ultrasound images, OCT uses light waves instead of sound waves, and is now being applied in a novel way for intraoperative margin visualization. Cleared by the FDA, the Perimeter S-Series system provides cross-sectional images of tissues down to 2mm depth, with 10x higher image resolution than standard x-ray and ultrasound, and 100x greater than MRI. Perimeter is developing its proprietary, next-gen “ImgAssist” artificial intelligence technology under the ATLAS AI project, made possible, in part, by a $7.4 million grant awarded by the Cancer Prevention and Research Institute of Texas (CPRIT). FDA granted Breakthrough Device Designation for Perimeter B-Series OCT coupled with ImgAssist AI. A randomized, multi-site, pivotal study is underway to evaluate this technology against the current standard of care and assess the impact on re-operation rates for patients undergoing breast conservation surgery.

We’re excited to see Claire featured in a recent article in Radiology Today! Thank you to Radiology Today Magazine and Beth Strohbusch for the coverage, and to Dr. Teresa Reading of Intermountain Health for sharing her clinical experience. https://www.radiologytoday.net/improvement-at-the-margins/

Claire is an FDA-approved device that images excised breast tissue right in the operating room. It’s designed to enhance surgeons’ ability to detect difficult-to-see cancer during lumpectomies as an adjunct to standard intraoperative margin assessment, giving the surgical team additional high-resolution insights.

Claire uses Perimeter’s wide-field OCT imaging system combined with AI, and trained users at the facility are involved in every step of the workflow, from preparing and scanning the specimen to image interpretation. The AI flags areas for the surgeon to review, and the surgeon makes all clinical decisions.

Curious to see what Claire can do for your surgical team? https://perimetermed.com/products/perimeter-claire/

Note: The Claire OCT System is an adjunctive tool; it does not replace standard tissue histopathology nor provide a diagnosis. For additional safety information, visit https://perimetermed.com/claire-disclosures/. For full clinical trial information, visit https://clinicaltrials.gov/study/NCT05113927. Perimeter's S-Series System is cleared by FDA for general imaging and not specifically for use in cancer surgery.

We are honored that Claire™ has been recognized among a select group of special mentions on the 2026 TIME Best Inventions list!

Claire images excised breast tissue right in the operating room. It’s designed to enhance surgeons’ ability to detect difficult-to-see cancer during lumpectomies, giving the surgical team high-resolution insights while they can still change the outcome.

Thanks , for the recognition. https://time.com/collection/best-inventions-special-mentions/2026/?filters=Medical+%26+Healthcare

A single cancer cell is microscopic, roughly 10 to 20 micrometers (µm) in diameter* meaning that more than a million cancer cells could fit on one sesame seed. Each one far too small for the naked eye to see.

That’s the trouble with trying to visualize microscopic disease. At the edge of removed tissue, everything can look and feel normal. But cancer cells can still be there.

During breast-conserving surgery, the surgeon has to decide: take more tissue, or close? That decision, about cells too small to visualize, can mean the difference between one surgery and a return to the operating room.

What do clear margins mean for breast cancer surgery? It’s a key milestone that means no cancer was left behind, clearing the path to move on to the next phase of treatment.

Conversation about margins matters. If you're facing breast cancer surgery, consider asking your surgeon about margins and what that means for your specific case.

Jennifer Douglas (), patient advocate and breast cancer survivor, breaks down what you should know about margins in breast cancer surgery➡️ https://jenniferadouglas.com/what-are-clear-margins-in-breast-cancer-surgery/

The space between a high jumper and the bar decides everything. Clear it by the wisp of a hair, and the jump counts. Touch the bar, even just slightly, and it may fall.

Breast cancer surgery has a margin, too.

Surgeons remove tumors with a rim of healthy tissue. That rim is called the margin. After surgery, a pathologist confirms whether cancer cells hit the margin.

If they don't, the margin is "clear." If they do, even barely, it's "positive." That means cancer cells may remain in the breast. Many patients with positive margins need another surgery.

In breast cancer surgery, margins matter. Because when it comes to removing cancer, clearing the bar is everything.

130 years ago, there was only ONE choice.

Full removal of the breast was the only surgical option for breast cancer treatment, until surgeons began lumpectomies in the 1980s.

Today, women have options to treat breast cancer. Because of research. Because of innovation. Because patients and healthcare professionals refused to accept that there was only one way.

But we’re not done. One in five women (21.1%) undergoing a lumpectomy must return for a second surgery simply because microscopic cancer cells, invisible to the naked eye, get missed during the initial procedure.

This October, we celebrate the many innovations that have improved breast cancer care for women. And we remain focused on transforming breast cancer surgery with advanced imaging that helps surgeons see what the naked eye cannot.

Breast cancer doesn’t just affect the patient, it impacts the entire family.

Perimeter's VP of Sales Abbey Goodman and her mother-in-law, Mary, recently shared Mary’s experience with DCIS and how her breast cancer journey affected both her and her family.

Today, nine years later and thanks to the incredible support of her medical team and family, Mary is thriving.

For Abbey, this personal connection is what drives her every day. Her work at Perimeter is fueled by a passion to transform the future of breast cancer surgery and improve the lives of patients across the country.

Tune in to hear CEO Adrian Mendes chat about the future of breast conserving surgery.

Why do patients need second surgeries? What changes when surgeons have real-time answers? And how is AI helping solve tough problems in breast cancer care?

Great conversation on Empowered Patient Podcast about the problems we're solving and the potential impact on the whole healthcare system.

Your Breast Density Matters, Here's Why:
When dense breast tissue is imaged on a standard mammogram, it appears white. So does cancer.

Imagine driving through a snowstorm: it’s hard to see the road ahead clearly when snow is falling all around you. The same applies to imaging of dense breasts.

Understanding your density is the first step toward better screening. If you have dense breasts, talk with your doctor about advanced imaging options that help provide enhanced visibility.

Want to learn more? Organizations like also offer patient-friendly information to help you understand your density and screening choices.
