Abstract
A high dose output, through transmission 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 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.

An X-ray tube for accelerating electrons under a high voltage potential, said X-ray tube comprising:
- an evacuated housing that is sealed;
- a through transmission target anode structure disposed on said housing, said anode structure configured in a hemispherical shape having a 2D base creating a circle with a center;
- a cathode structure disposed in said housing, said cathode structure configured to deflect the electrons toward said anode structure;
- a filament disposed in said housing, said filament positioned proximate the center of the circle created by the 2D base of the hemispherical shape, and between said anode structure and said cathode structure;
- wherein said cathode structure is positioned approximate said filament at the center of the circle created by the 2D base of the hemispherical shape of the anode structure;
- and
- wherein said evacuated housing is configured to vacuum seal therein said anode structure, said cathode structure, and said filament.
A method to produce a monochromatic output X-ray spectrum, said method comprising the steps of:
- providing an X-ray tube for accelerating electrons under a high voltage potential, said X-ray tube comprising:
- an evacuated housing that is sealed, a through transmission target anode structure disposed on said housing, said anode structure configured in a hemispherical shape having a 2D base creating a circle with a center, a cathode structure disposed in said housing, said cathode structure is configured to deflect the electrons toward said anode structure, a filament disposed in said housing, said filament positioned proximate the center of the circle created by the 2D base of the hemispherical shape and between said anode structure and said cathode structure, wherein said cathode structure is positioned approximate said filament at the center of the circle created by the 2D base of the hemispherical shape of the anode structure, and wherein said evacuated housing is configured to vacuum seal therein said anode structure, said cathode structure, and said filament,
- filtering said output X-ray spectrum just below a K alpha energy of said at least one target element;
- and
- adjusting said cathode voltage just above said K alpha energy of said at least one target element.
