Abstract: A method and apparatus for delivering localized x-ray radiation to the interior of a body includes a plurality of x-ray sources disposed in a distal portion of a flexible catheter shaft. The plurality of x-ray sources are secured to a flexible cord disposed longitudinally throughout at least a portion of the shaft. The plurality of x-ray sources are electrically coupled to a control circuit for activating specific ones of the plurality of x-ray sources in order to customize the irradiation of the interior of the body.
