Miniature x-ray emitter having independent current and voltage control |
摘要 |
An apparatus for emitting x-rays comprises a housing which contains an anode having an electron receiving surface and a cathode having an electron emitting surface. A cable couples the anode to a source of high voltage. An optical fiber secured to the cable has a proximal end coupled to a source of optical energy and a distal end configured to direct the optical energy onto the cathode's electron emitting surface. The cathode emits electrons which strike the anode to create x-ray radiation.
