Abstract: A high dose output, through transmission and reflective target x-ray tube and methods of use includes, in general an x-ray tube for accelerating electrons under a high voltage potential having an evacuated high voltage housing, a hemispherical shaped through and reflective transmission target anode disposed in said housing, a cathode structure to deflect the electrons toward the hemispherical anode disposed in said housing, a filament located in the geometric center of the anode hemisphere disposed in said housing, a power supply connected to said cathode to provide accelerating voltage to the electrons.
