Abstract: A modulated x-ray system and method provide various applications to increase medical diagnoses and treatment as well as non-medical scenarios. At low energy levels, it is used as a sophisticated medical diagnosis tool, localizing and imaging a variety of biological systems and conditions for further characterization, rather than for destruction. As a therapeutic device, it is used for directed treatment of infectious diseases, treatment of general medical diseases such as atherosclerosis and autoimmune diseases, and genetic therapy. In one embodiment, eliminating unwanted tissue anywhere in the body, effectively allows non-invasive surgery. In another embodiment, selective destruction/activation of specific cells allows for regeneration of cells and tissues, such as spinal cord regeneration.

Abstract: Radiation of specific material within a subject is accomplished by use of a beam of x-radiation modulated at a microwave frequency. The beam with its modulation is directed at the subject wherein the material interacts with the beam to extract a portion of the radiant energy carried by the beam. In the interaction, an electric field at the modulating frequency appears at the material. By selecting the modulated frequency equal to a resonant interactive microwave frequency of the material, a photon at the microwave frequency is absorbed by the material to alter its physical and chemical properties. By way of example, the material may be an oncogene or virus having a macromolecule and constituting a malignancy within a living subject. Absorption of the modulated radiation selectively destroys the malignancy. The klystron is disposed along the path of an electron beam in an x-ray source for modulating the electron beam and the resulting x-ray beam.
