frameless stereotaxy
A surgical navigation technique that uses real-time imaging and computer guidance without requiring a rigid frame attached to the patient's head.
Full Definition
Frameless stereotaxy is an advanced neurosurgical navigation system that provides precise three-dimensional localization during brain surgery without the need for a traditional stereotactic frame. The system uses preoperative imaging data combined with intraoperative registration to guide surgical instruments to specific targets. This technology allows for greater patient comfort and surgical flexibility while maintaining high accuracy for procedures such as tumor resection, biopsy, and electrode placement.
Usage
Usage note: Often abbreviated as 'neuronavigation' in surgical reports; distinguish from frame-based stereotactic procedures.
