Abstract

A tiered communications architecture for managing network traffic in a distributed system. Communication between client or control computers and a plurality of hardware devices is administered by agent and monitor devices whose activities are coordinated to reduce the number of open channels or sockets. The communications architecture also improves the transparency and scalability of the distributed system by reducing network mapping dependence. The architecture is desirably implemented in a proton beam therapy system to provide flexible security policies which improve patent safety and facilitate system maintenance and development.

Claims

1. A proton beam therapy device communication system, the system comprising:

a treatment station, having a plurality of hardware subsystems, that directs a proton beam towards a patient isocenter; and

one or more host applications that monitors and controls operation of the treatment station; and

an agent system connected to each host application using a single client data channel per host application, and further connected to each hardware component using a single data channel per hardware subsystem, wherein the agent system multiplexes operations between the one or more host applications and the plurality of hardware subsystems such that the one or more host applications and one or more of the plurality of hardware subsystems can be selectively removed without reconfiguration of the proton beam therapy device communication system thereby increasing scalability and flexibility of the treatment system, and wherein the agent system maps information from the one or more host applications to one or more proctors configured to monitor operational parameters of the plurality of hardware subsystems.

2. The system of claim 1, wherein the plurality of hardware subsystems is at least one of a proton beam transport system, safety system, power system, and a logging system.

3. The system of claim 2, wherein the proton beam transport system manages and monitors redirection of the proton beam from a beam source to the patient isocenter.

4. The system of claim 2, wherein the safety system monitors operational parameters of the treatment.

5. The system of claim 2, wherein the power system manages and monitors a power supplied to the treatment station to generate the proton beam.

6. The system of claim 2, wherein the logging system monitors and logs operation parameters of the treatment station.

7. A proton beam therapy device communication system, the system comprising:

a treatment station, having a plurality of hardware subsystems, that directs a proton beam towards a patient isocenter; and

one or more host applications that monitors and controls operation of the treatment station; and

one or more proctors that monitors the hardware subsystems, wherein the one or more proctors monitor operational parameters of the hardware subsystems; and

an agent system connected to each host application using a single client data channel per host application, and further connected to each hardware component using a single data channel per hardware subsystem, wherein the agent system performs routing operations between the one or more host applications and the plurality of hardware subsystems such that each host application can communicate with each hardware subsystem without specific knowledge of where each hardware subsystem is located in the communication system thereby increasing scalability and flexibility of the treatment system;

wherein the agent system maps information from the one ore more host applications to one or more proctors, wherein the mapping determines a network location for each of the hardware subsystems.

8. The system of claim 7, wherein the agent maintains a lookup table for mapping the information from the one or more host applications to the one or more proctors.

9. The system of claim 8, wherein the lookup table logs a network address of the one or more host applications.
