Perimeter’s advanced technology delivers subsurface images of excised tissue microstructures associated with hard-to-detect disease, with 10x the image resolution of standard X-ray and ultrasound at 2 mm imaging depth. Clinical guidelines state that 2 mm of clear margins produce the best outcomes for patients undergoing tissue excision assessment.8

Watch the clips below to see how one surgeon has incorporated OCT technology into her OR workflow — and now has the tools to visualize margins with ultra-high-definition imagery.

Incorporating OCT into the workflow

Perimeter’s OCT technology fits readily into the workflow as an adjunct to specimen X-ray and pathology, and it’s portable so it can be easily moved into any OR.


Interacting with the software & scanning the specimen

Surgeons can label and capture images of surgical margins on all six planes, with a scan time of 1-2 minutes per margin, to convey accurate orientation for pathology.


Interpreting OCT images to inform decision-making

Ultra-clear subsurface imagery and image review manipulation tools make it easy for surgeons to identify regions of interest for optimized decision-making in the operating room.


Prepping for pathology

Tissue is entirely preserved and the device does not touch the patient or enter the sterile field. While OCT does not replace histopathology, it can provide guidance for the pathology team.

Use of adjunct wide-field optical coherence tomography to visualize margins during breast conserving surgery for ductal carcinoma in situ: a case series

Amelia Tower, DO, FACOS; Mar. 21, 2023

Three women with biopsy confirmed DCIS and/or IDC undergoing breast-conserving surgery had their lumpectomy tissue imaged using intraoperative specimen radiography followed by WF-OCT imaging. With OCT, the surgeon was able to identify regions of interest that were not detected with specimen radiography and made the decision to excise additional tissue during the primary surgery. Pathology confirmed that all final margins were negative for residual disease, saving these 3 patients from the need for a second surgery.

Getting clean margins remains a challenge for surgeons. Hear from breast surgeons Dr. Michele Carpenter, who described OCT as “like having a pathology slide in the OR,” and Dr. Beth DuPree, an early OCT user.

Dr. Carpenter describes how Perimeter’s OCT technology is the closest thing to having a Pathology slide in her operating room.

OCT vs. X-ray

Information Sheet

Since positive surgical margins can lead to re-excisions, determining clear margins at the time of surgery is vital. Traditional imaging technologies like X-ray do not have the resolution needed to visualize margins at the cellular level, and all residual disease cannot be detected in the cavity by sight or palpation. Surgeons need advanced technology support in the OR to optimize clinical decision making.
