An operation to treat brain tumors can be performed in as little as a few minutes and does not require opening the patient's skull. This is far beyond an idea. A gyroscopic machine is designed to eliminate brain tumors without any cutting. It is called ZAP-X, which means to defeat tumors by X rays. The device among the latest advancements, will soon be available in hospitals in China. CGTN's reporter Liu Jiaxin spoke to the founder and CEO of Zap Surgical Systems, John Adler, about the technology.
