Our Technologies
NDI provides two industry-leading tracking technologies:
- Optical tracking systems for precise, 3D navigation of surgical tools, essential in advanced applications like robotic and computer-assisted surgeries.
- Electromagnetic (EM) tracking systems for in-body instrument tracking, even when visual access is limited
Both platforms are designed to integrate directly into your medical devices, delivering real-time data and dependable performance, precisely where you need it. Their accuracy and versatility make them essential in today’s most advanced clinical and surgical applications across the MedTech landscape.
Optical Navigation
NDI’s Polaris® optical navigation solutions provide sub-millimeter accuracy and precision for image-guided procedures, including robotic and computer-assisted surgeries. Every day, we are driven by a commitment to develop solutions that make healthcare better. This passion motivates us to continually expand our portfolio of optical navigation technologies to meet diverse clinical needs.
For optical navigation, NDI offers advanced optical tracking cameras and a range of optical markers designed for seamless integration.
- The Polaris Vega® and Polaris Lyra® cameras deliver real-time tracking of surgical tool positions and orientations within the operative field. With multiple models available, NDI provides options tailored to varied clinical and technical requirements, including hardware size, measurement rate, latency, noise levels, accuracy, data connectivity, and mounting flexibility.
- Our Passive and Active optical markers are engineered specifically to work with Polaris Vega and Lyra cameras. OEMs can select markers that best suit their clinical applications and workflow demands.
- NDI software packages help our OEM partners to configure, characterize, and track surgical tools, ensuring a smooth and efficient product integration experience.
NDI’s optical technologies support a wide range of clinical applications, including:
- Neurosurgery: Enhancing navigation accuracy in brain surgeries.
- Spinal Surgery: Assisting with accurate and safe pedicle screw placement.
- Orthopedic Surgery: Supporting patient-specific bone resection and implant placement.
- Radiation Therapy: Improving targeting accuracy for cancer treatments.
- External Neuromodulation: Enabling non-invasive brain stimulation for neurological and psychiatric disorders.
Electromagnetic Tracking
NDI’s Aurora® and 3D Guidance® systems enable real-time tracking of instruments inside the body without requiring a direct line of sight. This unique capability, combined with the small size of EM sensors, empowers OEMs to develop advanced, minimally invasive solutions.
NDI’s electromagnetic tracking system includes key components engineered for dependable performance in medical device applications:
- Transmitters/ Field Generators create a low-intensity electromagnetic field that defines the space where sensors are tracked. Various models are available to fit different clinical setups and workflows.
- Sensors are small devices embedded into OEM instruments like catheters, scopes, and needles. They detect their exact position and orientation within the electromagnetic field, enabling real-time tracking inside the body.
- Electronic Units/ Sensor Interface Unit (SIU) and System Control Unit (SCU) work together to amplify, process, and convert sensor signals into precise location data. This information is then shared with the OEM system to guide instruments accurately during procedures.
NDI’s electromagnetic technologies support a broad range of clinical applications, including:
- Interventional Radiology: Enabling precise navigation during minimally invasive image-guided procedures.
- Spinal Surgery: Assisting with accurate placement and navigation in spinal interventions.
- Ear, Nose, and Throat (ENT) Surgery: Supporting precise instrument tracking in ENT procedures.
- Pulmonology/Bronchoscopy: Facilitating navigation during airway interventions.
- Electrophysiology and Endovascular Surgery: Allowing accurate instrument tracking without interference during fluoroscopy.
By serving these diverse clinical markets, we aim to support our OEM partners in improving patient outcomes and assist healthcare professionals by delivering reliable, high-quality medical technology solutions.
Every day, we push the boundaries of tracking technology, helping our partners deliver better care, today and into the future.
