Ascension driveBAY
Ascension makes 3D tracking devices for medical guidance, minimally invasive surgery, real-time visualization, and target acquisition. Our position and orientation tracking devices navigate, localize, and guide medical instruments for image-guided procedures. They also capture human motions for interaction with 3D graphical worlds and biomedical analysis. From our pioneering Flock of Birds to our newest 3D Guidance trackers, Ascension’s innovative technologies can solve your 3D tracking needs.
driveBay is metal tolerant, that is output is unaffected by composite materials. Capable of driving errors induced by highly constructive metals (such as aluminum) to zero by adjusting measurement rate. Using advanced magnetic technology and signal processing the driveBay features improved dynamic performance over longer ranges and “Power-line” noise filtered out. The driveBay is also occlusion and drift free removing the requirement for clear line-of-sight between transmitter and sensor(s).
Key Features
- Minimal footprint: electronics unit fits into your PC’s drive bay.
- Fast 3D tracking: 240 – 420 updates per second.
- Small, lightweight 6DOF sensors for unobtrusive tracking and instrument tip guidance.
- Multiple magnetic field transmitters (generators) for extended tracking ranges.
- Immunity from most conductive metal distorters of accuracy.
- A attitude: no inertial drift or optical occlusions.
- Tracks 1 to 4 6DOF sensors simultaneously.
Tracker electronics inside your PC. “The driveBAY is the latest addition to the Ascension 3D Guidance family of ultra-fast trackers of small magnetic sensors. Users can select update rates as high as 420 times a second for each of four miniaturised sensors. The module fits into your PC’s drive bay.” Jeff Ferguson, Immersive Technologies Consultant.
