Atracsys is proud to introduce the spryTrack system that represents the vision of the future for computer assisted surgery. A compact solution for integration into your application.

In addition, it is:

Adaptable: can be adjusted to any set without any wires.
Affordable: as it offers competitive pricing in the marketplace.
Accessible: as it is easy to retrieve data on your tablet via Bluetooth.
Autonomous: as it has battery power, which is optional.

The extremely compact spryTrack is composed of two cameras designed to detect and track fiducials (reflective spheres, disks and/or IR-LEDs) with high precision in real time video streams. Triangulation enables retrieving 3D position of each fiducial with sub-millimetric accuracy. When several fiducials are affixed to a marker, its pose (orientation and  position) is calculated with 6 degrees of freedom (x,y,z,α,β,γ). The spryTrack has the ability to provide 3D positions of the fiducials, and/or poses of the markers.

The spryTrack offers both a USB 3.0 Type C (for power and/or data) as well as a Bluetooth connection (for data only) allowing a wireless link to a tablet on which the navigation application runs. A PC is no more needed. An optional battery pack enables complete mobility.

The SDK allows access to data at different stages of processing, starting from raw images, individual 3D positions of fiducials, and up to the pose of markers. The SDK also provides multi-level fault checking. This makes it possible to access error information in real-time at any processing stage: fiducial occlusion level, stereo de-calibration, marker registration error and more.
