Abstract
Abstract A device suitable for insertion into a body and for delivery of x-ray radiation, comprising a connector, a diamond vacuum housing coupled to a distal portion of the connector, an anode and cathode, disposed within the vacuum housing and arranged to enable the production of x-ray radiation. Also, a device suitable for insertion into a body and for delivery of x-ray radiation including a vacuum housing coupled to a distal portion of a connector where the vacuum housing has a diameter of less than 2.5 mm. A method of fabricating a miniature x-ray emitter by constructing a structure of diamond that defines a vacuum chamber and encases a cathode and an anode.
