Abstract
Abstract The present invention is directed to a method of treatment room selection verification in a radiation beam therapy system. The method compares treatment room beam request signals with a beam path configuration signal from a switchyard which controls the path of beam travel from an accelerator to one of the treatment rooms. Upon agreement of the request and beam path signals, beam transport to a selected treatment is authorized.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
90 words
A method of treatment room selection verification in a radiation beam therapy system comprising radiation beam source, beam accelerator, plurality of treatment rooms and a switchyard for directing accelerated beam from the accelerator to a selected one of the treatment rooms, the method comprising the steps of: (a) receiving a beam request signal from one or more of the treatment rooms; (b) verifying the authenticity of one of the beam request signals from one of the treatment rooms; and (c) authorizing beam transport to the one of the treatment rooms.
Claim 2
Independent Claim
90 words
A method of treatment room selection verification in a radiation beam therapy system comprising radiation beam source, beam accelerator, plurality of treatment rooms and a switchyard for directing accelerated beam from the accelerator to a selected one of the treatment rooms, the method comprising the steps of: (a) receiving a beam request signal from one or more of the treatment rooms; (b) verifying the authenticity of one of the beam request signals from one of the treatment rooms; and (c) authorizing beam transport to the one of the treatment rooms.
Claim 3
Dependent Claim
34 words
The method of claim 1 wherein steps (b) and (c) comprise comparing the beam request signal with a beam path configuration signal from the switchyard and authorizing beam transport upon agreement of the signals.
Claim 4
Dependent Claim
22 words
The method of claim 2 further comprising (d) denying beam transport to the selected treatment room in the absence of such verification.
Claim 5
Dependent Claim
48 words
The method of claim 1 further including generating a beam path configuration signal indicative of the beam path through the switchyard and wherein steps (b) and (c) comprise comparing the beam request signal with a beam path configuration signal and authorizing beam transport upon agreement of the signals.
Claim 6
Dependent Claim
22 words
The method of claim 3 further comprising (d) denying beam transport to the selected treatment room in the absence of such verification.
Claim 7
Independent Claim
117 words
A method of treatment room selection verification in a radiation beam therapy comprising radiation beam source, beam accelerator, plurality of treatment rooms and a switchyard for directing accelerated beam from the accelerator to different selected ones of the treatment rooms, the method comprising the steps of: (a) receiving a plurality of input signals comprising beam requests from the treatment rooms and a beam path configuration signal from the switchyard identifying a beam path through the switchyard to one of the treatment rooms; (b) comparing the input signals to verify the authenticity of a request from a selected one of the treatment rooms; and (c) in response to such verification, allowing beam transport to the selected treatment room.
Claim 8
Independent Claim
117 words
A method of treatment room selection verification in a radiation beam therapy comprising radiation beam source, beam accelerator, plurality of treatment rooms and a switchyard for directing accelerated beam from the accelerator to different selected ones of the treatment rooms, the method comprising the steps of: (a) receiving a plurality of input signals comprising beam requests from the treatment rooms and a beam path configuration signal from the switchyard identifying a beam path through the switchyard to one of the treatment rooms; (b) comparing the input signals to verify the authenticity of a request from a selected one of the treatment rooms; and (c) in response to such verification, allowing beam transport to the selected treatment room.
Claim 9
Dependent Claim
45 words
The method of claim 6 wherein the input signals further include beam configuration request signals from the treatment rooms and a beam configuration signal from the accelerator and the comparing of the input signals verifies the authenticity of the requests from the selected treatment room.
Claim 10
Dependent Claim
23 words
The method of claim 7 further including using the beam configuration request signals to control the configuration of the beam from the accelerator.
Claim 11
Dependent Claim
15 words
The method of claim 8 wherein the input signals further include treatment room configuration signals.
Claim 12
Dependent Claim
15 words
The method of claim 7 wherein the input signals further include treatment room configuration signals.
Claim 13
Dependent Claim
31 words
The method of claim 6 further including using the treatment room beam request signals to control the beam path through the switchyard and the beam path configuration signal from the switchyard.
Claim 14
Dependent Claim
22 words
The method of claim 6 further comprising (d) denying beam transport to the selected treatment room in the absence of such verification.
Claim 15
Dependent Claim
84 words
The method of claim 6 further comprising generating a treatment room selection signal for the selected treatment room upon agreement of the beam request input signal from the selected one of the treatment rooms and the input signal from the switchyard and wherein the verification further comprises gating with the treatment room selection signal a plurality of treatment room configuration signals from the selected treatment room to beam controllers in the switchyard to control the transport of the beam to the selected treatment room.
