San Carlos, CA – September 10, 2025 – ZAP Surgical Systems, Inc., a global leader in non-invasive robotic brain surgery, today announced its debut at the 2025 ASTRO (American Society for Radiation Oncology) Annual Meeting, to be held September 28 – October 1 in San Francisco, California. ZAP Surgical will showcase the ZAP-X® Gyroscopic Radiosurgery® platform to the ASTRO community, alongside its internationally recognized, award-winning ZAP-Axon® Radiosurgery Planning System.*
Attendees will have the opportunity to explore a near-full-scale model of the ZAP-X system, a dedicated cranial radiosurgery (SRS) innovation that eliminates the need for costly radiation-shielded vaults and replaces outdated Cobalt-60 sources with advanced linear accelerator technology.
Live demonstrations of the ZAP-Axon planning software will also be available, offering a hands-on look at ZAP’s next-generation approach to stereotactic radiosurgery (SRS) planning.
“We are honored to bring ZAP-X to ASTRO for the first time,” said John R. Adler, MD, founder and CEO of ZAP Surgical, and Emeritus Dorothy & TK Chan Professor of Neurosurgery and Radiation Oncology at Stanford University. “With its dedicated cranial SRS design, ZAP-X empowers radiation oncologists to efficiently delivery the highest quality care without the compromises commonplace with multi-purpose radiation delivery systems.”
The ZAP-X system leverages gyroscopic mobility to deliver radiosurgical beams from thousands of unique angles, enhancing dose shaping and aiding the sparing of healthy brain tissue and critical structures. This high-precision approach not only helps reduce treatment-related risk but also aims to better preserve mental function in patients undergoing brain radiosurgery.
“Focusing solely on conformality and dose gradient in cranial radiosurgery is outdated thinking. Recent studies reveal that multi-purpose radiotherapy systems can expose significantly more healthy brain tissue to unnecessary radiation, which early evidence suggests may lead to deleterious effects such as neurocognitive decline,” said Dr. Adler. “That’s a profoundly important distinction. Emerging research confirms that even low doses to healthy brain tissue significantly changes brain function.”
Throughout ASTRO 2025, Dr. Adler and the ZAP Surgical team will host a series of in-booth presentations introducing the ZAP-X technology and its unique value proposition for modern radiation oncology practices.
