ZAP Surgical, a pioneer in non-invasive robotic brain surgery, has received both U.S. Food and Drug Administration (FDA) 510(k) clearance and CE mark certification for its ZAP-Axon radiosurgery planning system.

ZAP-Axon is dedicated exclusively to cranial stereotactic radiosurgery (SRS). According to the company, it removes the time-consuming and cumbersome interfaces of multi-purpose planning software originally built for full-body applications and diverse radiation delivery techniques. Instead, Axon provides a focused, intuitive environment where data visualization meets usability.

It was developed in parallel with the ZAP-X gyroscopic radiosurgery platform, allowing integration between planning and delivery for better efficiency and treatment precision.



Axon boasts a Krylov quadratic optimizer that helps safeguard critical brain structures by allowing clinicians to rapidly generate and compare candidate plans. A twenty minute process can now be done in about 30-45 seconds, the company said.

When paired with ZAP-X, Axon awakens the full potential of the vault-free, cobalt-free radiosurgery system. ZAP-X uses an advanced gyroscopic architecture to deliver thousands of potential non-isocentric beam angles for dose conformity and to preserve healthy tissue. This is without needing shielded treatment bunkers or radioactive sources.

“As the first system in its field built entirely on modern web technologies, Axon is uniquely positioned to rapidly integrate and fully harness the power of AI,” said Alex Maslowski, Ph.D., VP of software at ZAP Surgical. “We’re witnessing the beginning of an entirely new generation in high-precision radiosurgery planning.”
