The Time to Know is Now

Perimeter OCT Margin Imaging Technology

Re-excision surgeries due to positive margins are all too common. Surgeons need to know whether they have achieved clean margins during the initial surgery.

Harnessing the power of advanced technology, Perimeter Medical Imaging is driven to transform cancer surgery with advanced imaging tools. The Perimeter Optical Coherence Tomography (OCT) system provides high-resolution imaging to help cancer1 surgeons get clean margins in real time – when it matters most.

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.

Perimeter Medical Imaging has added unparalleled strength to my practice. Its real-time, high-resolution visualization of tissue features provides insight during surgery and supports my decision-making in the OR. Our shared commitment to the highest quality of care and to using advanced technologies, is a key strength of our collaboration with Perimeter and HonorHealth.

Sommer Gunia, DO, FACOS

This evidence-based OCT technology helps me enhance my practice of using multiple tools in the operating room to help ensure that my patients have the best possible outcome.

Amani Jambhekar, MD, MBA, FACS

Perimeter’s OCT technology has become integral in providing the best possible care to my patients.

Amelia Gunter, MD

I remember, as I was getting ready for surgery, Dr. Gunia said, ‘I’ve got this advanced imaging tool that’s going to give me additional insights.' I feel very blessed that my surgeon used this technology as part of her decision making during my surgery.

Eileen Sullivan, Patient

I'm grateful to have a technology available to me that could help shorten this journey and get me on the road to recovery.

Nadia, Patient

This technology can provide additional insights in the OR to support a surgeon’s decision making process and help address the possibility that they have to call a patient back for a second operation.

Beth DuPree, MD, FACS, ABOIM

I believe that this technology is the next giant leap in margin visualization.

Shawndeep S. Tung, MD

OCT allows our surgeons to see tissue at the cellular level, in real time, right in the OR—giving them greater confidence when they close. By using advanced technology to receive real-time insights, solutions like OCT support our efforts to provide more efficient, cost-effective, and value-based surgical care.

The S-Series OCT has a general indication and has not been evaluated by FDA for specific uses. More information here.
