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. An array of x-ray sources and detectors is arranged symmetrically about a site of the subject. Sequential activation of the x-ray sources along with a scanning of the microwave modulating frequency permits measurement of absorption of radiant energy at the various modulation frequencies. This information is used to select the appropriate modulation frequency.
