ZD (Zamorano-Duchovny) stereotactic aluminium frame is based on the centre-of-arc principle. It enables almost unlimited intracranial target while leaving a whole freedom of choice of trepanation access. The single point method of attachment to the headring is possible in any one of the four possible positions.
It guarantees an easy handling and a fast assembly.

A cheramic headring is also available, allowing the use of any type of MRI imaging system.
