What is it indicated for?
The Optical Tracking System (OTS) is a graphical planning tool that allows for pre-operative and operative planning of cranial and spinal surgical procedures. The OTS is indicated for use in cranial and spinal surgical procedures in which anatomical structures are not clearly visible or where a desired target is close to critical regions. Examples of such procedures using OTS with the Non-Invasive DRF include, but are not limited to:
Catheter shunt placement.
Craniotomies /
Tumor resections
Skull lesioning
Vascular malformations
Various ENT procedures
