Particle beam therapy system

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 plurality of beam transport systems communicated with said charged particle beam generator and transporting the charged particle beam emitted from said charged particle beam generator separately to said respective irradiation units in said plurality of treatment rooms;
• a first manual input device provided respectively in said plurality of treatment rooms or a plurality of control rooms formed corresponding to said plurality of treatment rooms, and inputting an irradiation ready state;
• a preparation confirming unit for confirming that, after a ready signal has been outputted from said first manual input device and the treatment room to which the charged particle beam is to be introduced has been selected, preparations for generation of the charged particle beam in said charged particle beam generator are completed and preparations for transport of the charged particle beam in the beam transport system for introducing the charged particle beam to the irradiation unit in the treatment room selected in response to the ready signal from said first manual input device are completed, followed by outputting ready information;
• a ready state display unit device provided in each of said treatment rooms or each of said control rooms and displaying the ready information for the corresponding treatment room;
• and
• a second manual input device provided in each of said treatment rooms or each of said control rooms, and inputting an irradiation start instruction.

A particle beam irradiating method for irradiating a charged particle beam emitted from a charged particle beam generator to a patient in selected one of a plurality of treatment rooms by an irradiation unit in the selected treatment room, the irradiating method comprising the steps of:

• when preparations for irradiation to the patient in the treatment room are completed, operating a first manual input device provided in the treatment room or a control room formed corresponding to said treatment room, thereby outputting an irradiation ready signal;
• thereafter confirming that preparations for beam transport in the beam transport system for introducing the charged particle beam to said irradiation unit in the selected treatment room are completed;
• displaying beam transport ready information upon the confirmation in the above step;
• and
• after displaying the beam transport ready information, operating a second manual input device provided in the selected treatment room or the corresponding control room, thereby outputting a signal instructing the start of irradiation.
