A Game Changer for Margin Visualization

Cancer surgeons have long recognized the challenge of achieving negative margins while preserving healthy tissue during surgery. Traditional intraoperative imaging modalities do not deliver the resolution to visualize microscopic features associated with cellular-level disease. And it’s several days or weeks before pathology reports on margin status are available. If histopathology shows positive margins, patients must typically return for another procedure due to cancer left behind.

Perimeter is looking to become the answer to intraoperative margin visualization with its OCT technology.

S-Series OCT

Changing the margin imaging paradigm

Our flagship product, Perimeter S-Series OCT (Optical Coherence Tomography) is a pioneering medical imaging system that provides cross-sectional, real-time margin visualization of excised tissue specimens in the operating room (OR).

The Perimeter system gives surgeons the ability to:

  • Visualize microscopic tissue structures associated with residual disease
  • Capture high-quality images of each margin, with the light vacuum power from the Specimen Immobilizer
  • Label orientation, measure and annotate regions of interest

Future AI in Clinical Development

Recognizing the unmet need, particularly in the field of breast cancer margin visualization, Perimeter has a randomized, controlled, multi-site, pivotal study underway. The investigational study is designed to evaluate Perimeter B-Series OCT2 with ImgAssist AI against the current standard of care and assess the impact on re-operation rates for patients undergoing breast conservation surgery.

2 Perimeter OCT B-Series is not available for sale in the United States. CAUTION – Investigational device. Limited by U.S. law to investigational use. Perimeter received U.S. FDA Breakthrough Device Designation for its Optical Coherence Tomography (OCT) Imaging System with ImgAssist AI in April 2021.

Powered by Optical Coherence Tomography (OCT)

The first of its kind

Perimeter’s technology uses Optical Coherence Tomography, an optical imaging technique that uses light to produce real-time, cross-sectional images of subsurface tissue structures. The technology was developed out of MIT in 1991 and has been successfully used in ophthalmology, cardiology, and dermatology. The Perimeter S-Series system is the first OCT imaging tool on the market for intraoperative margin visualization.

OCT benefits over traditional imaging:

  • The only intraoperative OCT imaging technology with the resolution to visualize tissue structures at the cellular level down to 2mm depth
  • 10x higher image resolution than X-ray and ultrasound
  • 100x greater image resolution than MRI
  • OCT volume correlates to histological appearance of tissue structures
  • Incredibly fast and portable, allowing for intraoperative tissue visualization in any OR
