Precision, proven in the operating room.
The A1 Stereotactic Frame reaches both cerebral hemispheres in a single session — with sub-millimetre accuracy, no skull pins, and a patient experience that is measurably better from setup to recovery.

“What once required two procedures now takes one — with no skull pins, faster setup, and a patient experience that is meaningfully better from start to finish.”
Dr. Mohamed Elsaeed, Director of Functional Neurosurgery
Where the evidence concentrates.
Across clinical use, the A1 Frame’s advantages cluster in three areas that matter most to surgical teams and patients alike.
Targeting accuracy
The frame’s physically reachable reference point and re-zeroing mechanism support consistent sub-millimetre trajectory accuracy, verified mechanically rather than reconstructed from software alone.
Operative efficiency
Simultaneous bilateral access removes an entire surgical session, a second anaesthesia event, and a separate recovery — cutting average operative time for bilateral procedures roughly in half.
Patient experience
Pin-free fixation behind the hairline leaves no visible scars, keeps the airway fully accessible for anaesthesia, and suits claustrophobic and awake patients who struggle with enclosing frames.
The evidence base.
Clinical evaluation of the A1 Frame is ongoing across partner institutions. Published findings, case series, and evaluation summaries are listed here as they are confirmed.

In the words of surgeons.
Being able to treat both sides in one session changed how I plan bilateral cases entirely.

The absence of skull pins made the biggest difference for my awake patients — far less anxiety going in.
