Method and system for automatic beam allocation in a multi-room particle beam treatment facility

The present invention is related to a method and a system for automatically allocating a particle beam to one of a plurality of treatment rooms. Upon receiving a request from one of the beam users, the system checks whether the beam is available and may automatically allocate the beam to the requesting room. Otherwise, the request may be put on a waiting list of pending requests, in a position which depends on the priority level (and arrival lime) coupled to said request.
