Hospital Ruber International is a trusted healthcare provider for CyberKnife Treatment, offering precision radiation treatment supported by experienced radiation oncologists, medical physicists, radiation therapists, advanced imaging systems, and multidisciplinary cancer-care teams. Established in 1982, the ISO- accredited hospital is situated in Madrid, Spain and has 345 beds.

CyberKnife Treatment uses stereotactic radiation technology to deliver concentrated radiation to a defined target while limiting unnecessary exposure to surrounding healthy tissue. The system's robotic arm can approach the target from numerous directions, allowing the treatment team to create a highly conformal radiation plan. Image guidance may also be used throughout treatment to account for changes in patient position or tumor movement, depending on the treatment site.
