Perimeter S-Series OCT

Introducing a New Imaging Device that Gives Surgeons Real-time Insights

Perimeter S-Series OCT:
The Power to See More

Perimeter’s new technology provides high-definition, 3D images of margins in the operating room.

This gives your surgeon the clarity to make informed decisions to act in the moment — when it matters most.

The Perimeter S-Series OCT uses ultra-high-resolution Optical Coherence Tomography (OCT), developed out of Massachusetts Institute of Technology (MIT) in 1991, which has been in other specialty areas for decades.

At 10X higher resolution than ultrasound and X-ray and 100X higher than MRI, OCT has the resolution to visualize margins like no other technology available.

The S-Series OCT has 510(k) clearance under a general indication and has not been evaluated by FDA specifically for use in breast tissue, breast cancer, other types of cancer, margin evaluation, and reducing re-excision rates. The safety and effectiveness of these uses has not been established. More information here.

Your Treatment Plan

Other therapies such as chemotherapy or radiation may take place before or after your procedure depending on your diagnosis.

Perimeter S-Series OCT is used in the operating room to visualize margins in as little as 15 minutes.

The cancerous tissue that is removed during surgery is sent to Pathology to confirm clean margins. Results may take from 2-7 days, or longer.

If the margins are not clean, you will most likely be asked to return for another surgery. This can add weeks to your journey.

When it is confirmed that the margins are clean (negative), you will be able to continue on with the next steps in your treatment plan, putting you one step closer to getting back to doing the things you love.
