Operational consistency of medical linear accelerators manufactured and commissioned in series

Operational consistency of medical linear accelerators manufactured and commissioned in series

The purpose of this study was to determine if medical linear accelerators (linac) produced by the same manufacturer exhibit operational consistency within their subsystems and components. Two linacs that were commissioned together and installed at the same facility were monitored. Each machine deliv...
