Perimeter's Advanced Imaging Technology Featured at Annual Clinical Assembly of Osteopathic Surgeons

Executive Summary

• Perimeter Medical Imaging AI announced that Dr. Amelia Tower, a leading breast surgical oncologist, will present clinical case series data on the use of the company's S-Series Optical Coherence Tomography (OCT) system at the 2025 Annual Clinical Assembly of the American College of Osteopathic Surgeons.
• The presentation highlights the practical application of the FDA-cleared S-Series OCT for margin visualization during breast-conserving surgery, aiming to reduce re-excision rates and improve surgical precision.
• The release also reiterates the status of the company's next-generation B-Series OCT with ImgAssist AI, which is currently under FDA evaluation and supported by a grant from the Cancer Prevention and Research Institute of Texas.

Key Details

• Presentation Details: Dr. Amelia Tower will deliver an oral presentation titled "Use of Adjunct Wide-field Optical Coherence Tomography to Visualize Margins During Breast Conserving Surgery: A Case Series" at the 2025 Annual Clinical Assembly (ACA).
• Event Information: The ACA is held September 17-21, 2025, in Salt Lake City, Utah, and is sponsored by the American College of Osteopathic Surgeons, convening over 1,200 multi-disciplinary surgeons.
• Product Focus (S-Series): The presentation focuses on the Perimeter S-Series OCT, which received U.S. FDA clearance in 2021 under a general imaging indication. The technology provides real-time, cross-sectional visualization of excised tissues at the cellular level.
• Product Focus (B-Series): The release notes that the investigational Perimeter B-Series OCT with ImgAssist AI is currently under FDA evaluation specifically for intraoperative breast cancer imaging.
• Funding/Grants: The B-Series development is supported by a grant of up to US$7.4 million awarded by the Cancer Prevention and Research Institute of Texas.
• Clinical Context: The presentation addresses the issue of re-excision rates in breast-conserving surgery, arguing that advanced imaging tools can provide real-time insights to enhance surgical precision and reduce patient stress associated with repeat surgeries.
• Regulatory Status: The S-Series has 510(k) clearance under a general indication but has not been evaluated by the FDA specifically for breast tissue, breast cancer, margin evaluation, or reducing re-excision rates. The B-Series is limited to investigational use in the U.S.

Notable Quotes

• "Too many surgeries must be repeated simply because surgeons lack tools to see disease at the cellular level in real-time," said Dr. Amelia Tower. "When re-excisions are needed, patients face tremendous stress and often delayed follow-on treatment and recovery. Advanced imaging technologies, such as Perimeter's S-Series OCT, can provide real-time insights that enhance surgical precision and help us make the best decisions in the operating room."
