At ZAP, we know a thing or two about what comes next. In everything, we are a team motivated by a single question: Can a device address the limitations of the past to treat more people in more places? We believe it can.

We believe that ZAP-X® defines what’s next in radiosurgery for the brain.


Built upon a unique self-shielded design, ZAP-X eliminates the need for costly and complex shielded radiation vaults, unlocking point-of-care delivery in locations previously inconceivable.


As a simple solution for departmental expansions, ZAP-X now also makes SRS delivery feasible via more cost-efficient satellite facilities, physician offices and ambulatory surgery centers.


ZAP was founded in 2014 by Dr. John Adler, Professor of Neurosurgery and Radiation Oncology at Stanford University. Dr. Adler is also the inventor of the CyberKnife® Robotic Radiosurgery System and founder of Accuray, Inc. In 2018, Dr. Adler was awarded the American Association of Neurological Surgeons (AANS) Cushing Award for Technical Excellence and Innovation in Neurosurgery.


Global Healthcare Group Co. Ltd, GHG,  is the sole distributor of ZAP-X® in Hong Kong and Macau.
