Dr. John Adler: The Story behind CyberKnife & ZAP-X

Join us on the ERCM Medicine Podcast for a conversation with John R. Adler Jr., MD, the visionary inventor of the CyberKnife and founder of Zap-X. As a Stanford professor, Dr. Adler has revolutionized neurosurgery through the development of robotic radiosurgery systems. He shares his extraordinary journey – from being inspired by Lars Leksell at the Karolinska Institute in Stockholm to founding two groundbreaking medical technology companies. He speaks candidly about daily setbacks, the skepticism of colleagues (who initially called the CyberKnife „Adler's Folly“), and why persistence is the key to success. His provocative message to young innovators: „Don't do it – unless you're prepared to never give up.“ This episode provides an honest assessment of the challenges in translating medical innovations into clinical practice.
