Overview

The OTIS 2.1 Optical Coherence Tomography System, also known as THiA Optical Coherence Tomography System, is an advanced imaging tool developed by Perimeter Medical Imaging AI. It is designed for the evaluation of excised human tissue microstructure, providing two-dimensional, cross-sectional, real-time depth visualization. The system includes image review manipulation software that enables users to identify and annotate regions of interest within the tissue samples.

Utilizing Optical Coherence Tomography (OCT) technology, OTIS 2.1 operates similarly to ultrasound but employs non-ionizing, low-power optical radiation to generate high-resolution, sub-surface images of tissue. This technology is foundational to Perimeter Medical Imaging AI’s broader mission to transform cancer surgery, particularly in breast conservation, by providing surgeons with real-time insights to achieve clean margins and potentially reduce the need for re-excisions. While OTIS 2.1 itself is primarily an imaging device, it represents an earlier iteration of the company’s technology, which has since evolved into products like the S-Series OCT and the investigational B-Series OCT with ImgAssist AI, which incorporates artificial intelligence for enhanced detection capabilities.

What the Web Says

The OTIS 2.1 Optical Coherence Tomography system is an imaging tool designed for evaluating excised human tissue microstructure, providing real-time, two-dimensional, cross-sectional depth visualization. It offers high-resolution imaging, significantly more detailed than ultrasound or MRI, and aims to assist surgeons in assessing surgical margins to potentially reduce re-excision rates in cancer surgeries, particularly breast cancer. The system has received FDA 510(k) clearance for general use in evaluating excised human tissue.

Overall: Positive

Strengths

  • Provides real-time, high-resolution, sub-surface imaging of excised tissue.
  • Offers significantly higher resolution compared to ultrasound (10x) and MRI (100x).
  • Aids surgeons in intraoperative margin assessment, potentially reducing re-excision surgeries.
  • Non-destructive imaging, preserving tissue for subsequent histology.
  • Automates OCT scanning of the specimen surface, standardizing image collection.
  • Allows for concurrent image review and acquisition.

Limitations

  • The S-Series OCT (which includes OTIS 2.1) has a general FDA 510(k) clearance and has not been specifically evaluated by the FDA for use in breast tissue, breast cancer, other cancer types, margin evaluation, or reducing re-excision rates.
  • Without AI assistance, interpreting thousands of images generated during a scan can be time-consuming for surgeons.
  • Reimbursement pathways for new medical devices can take time (e.g., 6 months to 2-3 years).
  • The system requires a single-use consumable for each procedure.

Frequently Asked Questions

The OTIS 2.1 system automates the OCT scanning process and provides image review manipulation software for identifying and annotating regions of interest in excised human tissue microstructure. While the OTIS 2.1 itself is an imaging tool, its developer, Perimeter Medical Imaging AI, is actively developing a separate machine learning-driven AI system, 'ImgAssist AI,' to complement the OTIS platform for enhanced surgical margin assessment, particularly in breast cancer surgery.
The Perimeter OTISu2122 2.1 system received FDA 510(k) clearance in 2021 for use as an imaging tool to evaluate excised human tissue microstructure. This clearance pertains to the imaging system and its software for image review and annotation. Information regarding specific FDA clearance for integrated AI *diagnostic* features within OTIS 2.1 itself is not explicitly detailed in the provided search results, as the AI component ('ImgAssist AI') is described as a future development. For data privacy, general medical device regulations and best practices would apply, but specific details for OTIS 2.1 were not found in the provided context.
The OTIS 2.1 system, as an imaging tool, has undergone design verification and validation testing to demonstrate its safety and effectiveness, and its images are comparable to its predicate device, OTIS 2.0. For the separate, developing AI component ('ImgAssist AI'), a study on a deep learning model for breast cancer margin assessment using Wide Field OCT images achieved an AUROC of 0.976, with 93% sensitivity and 98% specificity in independent testing. This indicates strong potential for the AI in development.
The OTIS 2.1 system's current cleared indication is for imaging and identifying regions of interest, not autonomous diagnosis. While the developing 'ImgAssist AI' shows promise for breast cancer margin assessment, potential limitations for AI in medical imaging generally include biases from training data, which could affect performance across diverse patient populations or rare conditions. The current focus for the AI is on breast tissue, and its applicability to other tissue types would require further validation.
The OTIS 2.1 system offers high-resolution, real-time imaging of excised tissue margins, providing 100x more resolution than MRI and 10x greater resolution than ultrasound for intraoperative assessment. While other OCT systems exist, Perimeter's roadmap for 'ImgAssist AI' aims to integrate machine learning for enhanced decision support, potentially reducing re-excision rates in breast cancer surgery. Other AI-powered OCT solutions are emerging, particularly in ophthalmology for disease detection and progression monitoring, indicating a growing competitive landscape for AI in medical imaging.
Specific pricing for the Perimeter OTIS 2.1 medical imaging system is not publicly available in the provided search results. However, the company aims to launch commercially in early 2021, suggesting a standard sales model for medical devices. While the search results mention pricing for a different 'Otis AI' (a marketing tool), this is not relevant to the medical device. It is common for advanced software features, especially AI, in medical devices to involve additional licensing or subscription fees, but these details for Perimeter's 'ImgAssist AI' are not yet disclosed.
