Abstract:
The present invention provides electron beam therapies with improved feedback control that delivers controlled and adjustable doses of electron beam radiation to variable shallow depths with little radiation exposure to both nearby tissues and tissues below the target. In order to control radiation to accurately penetrate to shallow depths and to allow the radiation to be adjusted to other depth settings in very small or even continuous increments, the present invention senses a plurality of different electron beam characteristics and then uses these to derive a composite characteristic, or analog, of the electron beam energy. The composite analog provides a strong correlation to energy that allows this precision. In another aspect, the present invention relates to implementing this feedback control by adjusting power levels used to establish the electron beam. In other embodiments, feedback control adjusts absorbing components with variable electron beam absorption depending on how such components are presented to the electron beam.

Claim (Index 17):
An electron beam radiation system useful to irradiate a target site on a patient with an electron beam radiation dose having a controlled and adjustable penetration depth, said system comprising:\n a) a power source providing a power output; b) a microwave source that receives the power output from the power source and emits microwave energy; c) a microwave network that receives the microwave energy from the microwave source; d) an electron beam source that emits an electron beam; e) an accelerator system configured to receive the electron beam from the electron beam source and to receive the microwave energy from the microwave network in a manner effective to accelerate the electron beam toward the target site; f) a collimator that receives and shapes the accelerated electron beam; and g) a feedback control system, comprising:\n 1) a first electron beam sensor that measures a first characteristic of the accelerated electron beam; \n 2) a second beam sensor that measures a second characteristic of the accelerated electron beam that is different from the first characteristic; and wherein: \n the feedback control system uses first and second signals from the first and second sensors to derive an analog characteristic of electron beam energy; and \n the feedback control system uses the analog of electron beam energy to generate a control signal that controls the electron beam energy at a level that is in the range from 0.1 MeV to 6 MeV and that corresponds to a desired penetration depth at the target site.
