1. A particle therapy device comprising:
- an accelerator;
a particle beam delivery unit operable with the accelerator, the particle beam delivery unit operable to deliver particles to at least two irradiation positions; and
a control system configured to monitor the particles along a particle beam path, the control system comprising an assignment unit, at least one control unit disposed at one of the at least two irradiation positions and an accelerator control unit,wherein the at least one control unit is configured to emit a request signal that requests a particle beam for an irradiation procedure,wherein the assignment unit is configured to assign the particle beam path to the requesting irradiation position, and is connected to configurable elements that direct the beam path,wherein only those configurable elements that are required for the beam path are selectively activated, andwherein the accelerator control unit is configured to emit configuration parameters to the configurable elements, the assignment unit configured as a fail-safe control system such that the assignment unit sends an activation signal to the configurable elements of the beam path when setting up the particle beam path, the activation signal separate from the emission of configuration parameters from the accelerator control, the activation signal being present during the implementation of the configuration parameters and allowing the implementation of the configuration parameters.

14. A method for forming a beam path for an irradiation procedure in a particle therapy device which includes an accelerator and particle beam delivery unit operable to deliver particles to at least two irradiation positions and includes a control system operable to monitor and direct the particles along a particle beam path, wherein the control system comprises an assignment unit, a control unit arranged at each of the at least two irradiation positions and an accelerator control unit, the method comprising:
-
initiating the irradiation procedure by communication between a control unit and the assignment unit, wherein a beam request signal and, following an assignment of the particle beam to the requesting irradiation position, a confirmation signal confirming the request are exchanged, transferring configuration parameters from the accelerator control unit to configurable elements of the accelerator and a beam transport unit, wherein the assigned control unit transfers information about the irradiation procedure to be carried out to the accelerator control unit, and activating the required elements specified by an activation signal from the assignment unit, when setting up the particle beam path, separately from the transferring, and implementing configuration parameters transferred from the accelerator control unit when the activation signal is present. - View Dependent Claims (15, 16, 17, 20)
