1. A controller for a radiation therapy apparatus comprising:
- an interface configured to receive one or more inputs indicative of a state of one or more of a patient'"'"'s physiological parameters; and
a gating controller, said gating controller configured to vary a phase between an RF pulse and an injector pulse responsive to said one or more inputs.

Abstract
A radiation therapy device (2) configured to receive a signal indicative of one or more of a patient'"'"'s physiological parameters. The signal controls a gating, whereby a phase of an RF pulse (1002) and an injector pulse (1006) are varied so as to inhibit X-ray production without affecting injector or RF amplitudes.

11. A radiation therapy apparatus, comprising:
-
means for delivering a radiation dose to a patient; and a controller for receiving an input signal indicative of one or more of said patient'"'"'s physiological parameters, said controller configured to dynamically vary application of said dose responsive to said input, said controller configured to vary a phase between an RF pulse and an injector pulse responsive to said one or more inputs. - View Dependent Claims (12, 13, 14)

15. A radiation therapy system, comprising:
-
an apparatus for delivering a predetermined radiation dose to a patient; an interface configured to receive one or more input signals indicative of one or more of said patient'"'"'s physiological parameters; and a controller configured to vary a phase between an RF pulse and an injector pulse, whereby substantially no radiation is delivered to said patient when said RF pulse and said injector pulse are out of phase, and wherein said phase is varied responsive to said one or more signals indicative of one or more of said patient'"'"'s physiological parameters. - View Dependent Claims (16, 17, 18, 19)
