Computer-Assisted Therapy and Optical Tracking

To treat disease, physicians need to perform procedures that challenge their abilities to navigate anatomical structures and target affected tissue, while minimizing damage to healthy surrounding tissue. Computer-assisted therapy (CAT) and computer-assisted surgery (CAS) solutions assist physicians in overcoming these problems. This revolutionizes the way they diagnose and treat a number of conditions and diseases and, ultimately, minimizes the invasiveness of these procedures and improves patient outcomes, through reduced complications and improved patient safety.

Integrating the Polaris Spectra® Optical Measurement System into CAT applications enables physicians to overcome these challenges and better target diseased tissue while preserving healthy tissue and structures.

How does integrating the Polaris Spectra achieve this? Positioning NDI markers on the key tools used in the procedure as well as on the patient allow these tools and the patient to be tracked by the Polaris Spectra Position Sensor. Once the position sensor can track the tools and the patient, it can calculate the exact location and orientation of each item. With this location and orientation information known, the physical location of the patient can be aligned with pre-operative MRI data (or other medical images) and the exact location of tools can be tracked relative to the patient’s data. As a result, the physician can more accurately target disease, minimize invasiveness, and improve overall patient recovery. CAT procedures benefiting from NDI Polaris Optical System integration, include:

  • Ablation Therapy
  • Brachytherapy
  • Biopsy
  • Craniotomy
  • Deep Brain Stimulation
