Abstract:
1. A particle beam therapy system comprising: a charged particle beam generator for emitting a charged particle beam; a plurality of treatment rooms in each of which an irradiation unit for irradiating the charged particle beam is disposed; a first beam transport system connected to said charged particle beam generator and transporting the charged particle beam emitted from said charged particle beam generator; a plurality of second beam transport systems provided respectively corresponding to said treatment rooms, connected to said first beam transport system, and transporting the charged particle beam transported through said first beam transport system to the corresponding irradiation units disposed in said treatment rooms; a control information forming unit for forming control command information, which includes control information for a plurality of elements provided in the second beam transport system introducing the charged particle beam to the irradiation unit in the selected treatment room, by using at least treatment room information representing the selected treatment room and treatment plan information specified depending on patient identification information; a plurality of detectors for outputting detected signals representing at least respective status of said plurality of elements; and an information confirming unit for confirming that element status information based on the detected signals from said plurality of detectors are matched with said control command information; said control information unit forming, as said control command information for said plurality of elements disposed in said second beam transport system associated with said selected treatment room, control command information including control data for controlling said plurality of elements, while, for said plurality of elements disposed in said second beam transport systems other than said second beam transport system associated with said selected treatment room, forming control command information including no control data for controlling said plurality of elements, said information confirming unit effecting said confirmation as said control command information by receiving all of the status information for the elements of all of said second beam transport systems, and excluding, from said all of the status information, the status information for the elements corresponding to the control command information including no control data thereby to select only the status information for the elements corresponding to the control command information including the control data, and then confirming that the selected status information is matched with the control data included in said control command information; and said information confirming unit outputting an emission authorization signal after making said confirmation.
