Polaris Vega® VT
Envision new possibilities in OEM surgical tool tracking and navigation with the industry’s first optical tracker to combine live HD video and infrared (IR) tracking.
Our Specialized Optical Tracker that Supports Augmented Reality Applications
Our specialized optical tracker, the Polaris Vega® VT combines accurate optical measurement and live video streaming, which supports the development of augmented reality and machine vision in OEM surgical system workflows. As with all Polaris optical trackers, the Polaris Vega VT can track OEM surgical instruments via navigation markers. The HD video camera provides a live view of the instruments (and procedure occurring within the measurement volume) using a third-party streaming client.
IR tracking data and video data are aligned to a common coordinate system – the IR sensors and HD video camera see the same thing at the same time. There is no need to calculate the offset between the IR tracking data and video streams. Medical device OEMs can use this technology to enhance existing surgical approaches, or introduce augmented reality and machine vision capabilities to their systems; for example:
- Adding AR visualization of internal structures via image fusion
- Studying joint range of motion before/after implant surgery
- Registering tools automatically by scanning barcodes
- Augmenting patient case files with procedural recordings
- Consulting with remote staff via streamed video feed
- Recording pre-op rehearsals to enhance surgical planning
Exceptional Measurement Accuracy
The Polaris Vega VT delivers volumetric accuracy to 0.12 mm RMS at 60 Hz, with minimal noise while streaming video. Track with confidence; hardware characterization and factory calibration optimize accuracy for measurements that are highly repeatable and reliable.
| Volumetric Accuracy1,2 RMS | Pyramid Volume: 0.12 mm Extended Pyramid: 0.15 mm |
|---|---|
| 95% Confidence Interval1,2 | Pyramid Volume: 0.20 mm Extended Pyramid: 0.30 mm |
Integrated HD Video Camera
The Polaris Vega VT video camera provides a live view of the measurement volume via third-party streaming clients. Camera resolution, frame rate, and other features can be quickly configured in-field to capture sharp, high-contrast images in most operative environments.
| Resolution | Frames per Second | Horizontal Field of View | Vertical Field of View |
|---|---|---|---|
| 2048 x 1536 | 20 max. | 54.8° | 42.5° |
| 1920 x 1088 | 30 max. | 51.8° | 30.6° |
| 1024 x 768 | 47 max. | 54.8° | 42.5° |
Augmented Reality Overlay
The Polaris Vega VT software enables a live augmented reality overview of tools within the video stream, which is aligned to the IR data coordinate system. Create virtual tools and new video-enhanced applications using the built-in API and available software and source code.
| Tool Types | Passive, Active Wireless |
|---|---|
| Maximum Number of Tools | Load up to 25 tools (maximum of 6 active wireless) |
| Maximum Number of Markers per Tool | 6 single-face/20 multi-face |
Seamless Data Synchronization
The Polaris Vega VT uses the Precision Time Protocol (PTP) for network synchronization and the Real-Time Streaming Protocol (RTSP) for streaming video. Tight data communication and synchronization are achieved by Gigabit Ethernet, and system power via POE (Power over Ethernet).
| Measurement Rates | 20, 30, 60 Hz |
|---|---|
| Average Latency | < 16 ms (typical) at 60 Hz |
| Data Communication | Gigabit Ethernet |
| Video Streaming Protocol | Real-Time Streaming Protocol |
