Abstract

In a complex, multi-processor software controlled system, such as proton beam therapy system (PBTS), it may be important to provide treatment configurable parameters that are easily modified by an authorized user to prepare the software controlled systems for various modes of operation. This particular invention relates to a configuration management system for the PBTS that utilizes a database to maintain data and configuration parameters and also to generate and distribute system control files that can be used by the PBTS for treatment delivery. The use of system control files reduces the adverse effects of single point failures in the database by allowing the PBTS to function independently from the database. The PBTS accesses the data, parameter, and control settings from the database through the system control files, which insures that the data and configuration parameters are accessible when and if single point failures occur with respect to the database.

Claims

1. A radiation beam therapy system comprising:

a plurality of treatment devices, including;

a charged-particle accelerator that provides a beam of energetic charged particles;

a treatment station that allows positioning of a patient to receive at least a portion of the beam of charged particles; and

a beam delivery system that delivers the beam of charged particles to the patient positioned at the treatment location;

a database component that stores parameters associated with respective treatment devices, wherein the parameters comprise instructional information that can be used to configure the respective treatment devices for operation;

an interface component that allows a user to modify one or more parameters associated with a selected treatment device stored in the database; and

a management component that, in response to a user modification of one or more parameters,

retrieves a subset of parameters from the database, the subset of parameters including the one or more modified parameters,

generates a data storage element comprising the subset of parameters in a format recognizable by the selected treatment device, wherein the data storage element permits configuration of the selected treatment devices based, at least in part, on the subset of parameters, and

distributes the data storage element to the selected treatment device to thereby permit the selected treatment device to operate independently of the database component.

2. The system of claim 1, wherein the management component waits for administrator approval before retrieving the subset of parameters, generating the data storage elements, and distributing the data storage elements.

3. The system of claim 1, wherein the parameters include one or more of treatment data, configuration parameters, operations parameters, and control settings.

4. The system of claim 1, wherein the interface component allows the user to temporarily modify the one or more parameters.

5. The system of claim 4, wherein temporarily modified parameters expire after a predetermined period of time.

6. The system of claim 1, wherein the selected treatment device is software controlled and requires at least one of the parameters in the subset of parameters for operation.

7. A radiation beam management system configured to control a plurality of proton beam therapy systems that comprise treatment devices including a radiation beam source and a beam transport device, the radiation beam management system comprising:

a database that stores a plurality of parameters associated with respective treatment devices, wherein a parameter comprises instructional information that can be used to control a treatment device;

an interface that allows a user to modify one or more parameters of the plurality of parameters, wherein the one or more parameters are associated with a respective treatment device; and

a management component configured to, in response to a user modification of the one or more parameters,

retrieve a subset of parameters from the database, wherein the subset of parameters includes the one or more modified parameters,

generate a system control file comprising the retrieved subset of parameters, wherein the system control file is usable to control the respective treatment device based, at least in part, on the instructional information comprised therein, and

transmit the system control file to a proton beam therapy system associated with the respective treatment device, thereby permitting the respective treatment device to operate independently of the database.

8. The system of claim 7, wherein the proton beam therapy system comprises a control station, and wherein the management component transmits the system control file to the control station.

9. The system of claim 8, wherein the control station transmits the system control file to the respective treatment device.

10. The system of claim 9, wherein the respective treatment device is a proton energy source, an accelerator, a beam transport system, a switchyard, a gantry, or a treatment platform.

11. The system of claim 7, wherein the subset of parameters in the control file is arranged so as to enable the respective treatment device to recognize each of the parameters.

12. The system of claim 7, wherein parameters include one or more of treatment data, configuration parameters, operations parameters, and control settings.

13. The system of claim 7, wherein the interface does not allow the user to modify parameters while a patient is being treated by the proton beam therapy system.

14. The system of claim 7, wherein the system control file is a flat file or a binary file.

15. The system of claim 7, wherein the management component transmits the system control file to a plurality of proton beam therapy systems.
