The Zeta Navigation System is a stereotactic, image-guided planning and intraoperative guidance system enabling computer-assisted cranial surgical procedures. The system assists surgeons in the precise positioning of surgical instruments relative to patient anatomy by displaying the position of navigated surgical instruments relative to 3D preoperative medical scans. A core feature of the Zeta Navigation System is that it can provide surgical navigation without the need for rigid head immobilization, body-mounted frames, or fiducials, instead using its underlying RealTrack algorithm for accurate, real-time tracking of head movement using only the patient’s native anatomical features. This enables the ZETA system to be deployed in less acute surgical settings such as interventional procedure suites, with minimal setup time or workflow interruption, and relying only on non-procedure-specific 3D imaging. The Zeta Navigation System consists of a single cart, a software user interface, and a set of compatible navigated instruments, sterile equipment covers, and surgical drapes.
A mobile assembly of mains electricity (AC-powered) electronic and optical devices designed to receive and analyse patient magnetic resonance imaging (MRI) images and position landmarks manually or automatically on these images, then register the images by the mean of a three-dimensional (3-D) optical positioning system (frameless stereotactic neuronavigation) to provide real-time relative positioning for the treatment probes and instruments. It is typically used by healthcare providers in psychiatry, neuropsychiatry, and neurology for preoperative planning, in particular for consecutive image-guided transcranial magnetic stimulation (TMS) treatment sessions.
