Atracsys proposes two families of optical 3D localizers based on active and passive technologies.

accuTrack

Designed to be used close to the tracking site, accuTrack 500 and accuTrack 250 localizers optimize the working volume versus precision equation. accuTrack active system detects the sub-millimetric position of infrared LEDs at a maximum speed of 4000 Hz guaranteeing to capture moving objects without losing any precision.   (more)

infiniTrack

infiniTrack is a real-time 3D/6D optical measurement system specially designed to detect and track the pose of objects in real-time video streams. Being simultaneously an active camera as well as a real passive tracking system, infiniTrack can be used in an infinite number of applications and is compatible with existing image-guided surgery tools already widespread in the medical field.   (more)
