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

Leading breast surgical oncologist Dr. Amelia Tower to present on wide-field optical coherence tomography for margin visualization during breast conserving surgery

TORONTO and DALLAS, Sept. 19, 2025 /PRNewswire/ - Perimeter Medical Imaging AI, Inc. (TSXV: PINK) (OTCQX: PYNKF) ("Perimeter" or the "Company"), a commercial-stage medical technology company, announced that Dr. Amelia Tower, a leading breast surgical oncologist will present today at the 2025 Annual Clinical Assembly ("ACA") of the American College of Osteopathic Surgeons on the use of wide-field optical coherence tomography ("OCT") during breast conserving surgery.

In her oral presentation, "Use of Adjunct Wide-field Optical Coherence Tomography to Visualize Margins During Breast Conserving Surgery: A Case Series," Dr. Tower will highlight real-world cases demonstrating the practical application of Perimeter's current product, the S-Series OCT. The S-Series received U.S. Food and Drug Administration ("FDA") clearance in 2021 under a general imaging indication, and the performance of an AI-assisted version is currently under FDA evaluation specifically for use in intraoperative breast cancer imaging.

"Too many surgeries must be repeated simply because surgeons lack tools to see disease at the cellular level in real-time," said Dr. Tower, head of the newly formed Breast Associates of Texas in Fort Worth and an academic leader in medical education. "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."

Dr. Tower's presentation underscores the impact of re-excision rates in breast conserving surgery, the functionality of OCT, and outlines how surgeons can integrate the technology into their workflow. A board certified and fellowship-trained practicing surgeon, Dr. Tower has published extensively on surgical innovations. This presentation is being shared as scientific exchange, supplementing a growing body of clinical evidence on intraoperative margin assessment.

The ACA, sponsored by the American College of Osteopathic Surgeons, is a premier event that convenes more than 1,200 multi-disciplinary surgeons from across the country each year for networking and continuing medical education. The event is being held Sept. 17-21 in Salt Lake City, Utah.
