stereotaxy

Full Definition

Stereotaxy employs external reference frames and imaging guidance to achieve millimeter accuracy in targeting brain structures for procedures such as biopsies, electrode placement, or lesioning. The technique relies on mathematical calculations based on anatomical landmarks or imaging coordinates. Modern stereotactic procedures include frame-based and frameless systems, enabling minimally invasive approaches to deep brain structures while minimizing damage to surrounding tissue.

Usage

Usage note: Often confused with 'stereotactic' (the adjective); this is the noun form of the technique.

In Context
