The Optical Tissue Imaging System (OTIS™)

Perimeter Medical's Optical Tissue Imaging System (OTIS™) is an intra-operative imaging tool which provides surgeons, radiologists and pathologists with the ability to review tissue microstructure during surgery.

The OTIS™ is based on Optical Coherence Tomography (OCT), a non-contact and non-destructive imaging technique. OCT is analogous to ultrasound imaging, but uses light instead of sound to extract structural information to a depth of 1-2mm. OCT is a mature technology with commercial applications in ophthalmology and vascular imaging, where samples are small and smooth. Perimeter's novelty the ability to rapidly image large and complex tissue samples.

OTIS™ Delivers:

  • High-resolution subsurface images of intact excised tissue specimens
  • Automated full specimen scanning
  • Intra-operative, real-time results
  • Orientation representation
  • Non-destructive analysis (preserves entire sample for pathology)
  • Interdisciplinary clinical use

Clinical Example: OTIS™ Imaging of a Breast Lumpectomy Specimen
