Embodiment Construction

[0049] In describing exemplary embodiments of the present disclosure, such as Figure 1-3 , 3.1, 4-10, 11A, 11B, 12-13, specific terminology is used for the sake of clarity. However, the disclosure is not intended to be limited to the specific terms so selected and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to perform a similar function. The examples set forth herein are non-limiting examples and are merely examples of other possible examples.

[0050] now refer to figure 1 , shows a schematic cross-sectional representation of a Coolidge-type X-ray tube 12, as shown in Figure 1, comprising: an X-ray tube housing 1, which may be glass or metal; a high voltage insulator 2; In the X-ray tube housing 1. In a Coolidge tube, X-ray photons, shown as a fan-shaped output radiation pattern 7, are transmitted by impinging an electron beam (shown as electron trajectory 6) emanating from a filament 5 onto the sur...

Abstract

High dose output transmissive and reflective objective x-ray tubes and methods of use generally include an x-ray tube for accelerating electrons at a high voltage potential having: an evacuated high voltage housing; a hemispherical transmissive and reflective a target anode disposed in the housing; a cathode structure for deflecting electrons towards a hemispherical anode disposed in the housing; a filament located in the anode hemisphere disposed in the housing the geometric center of ; a power supply connected to the cathode to provide an accelerating voltage to the electrons.

Description

[0001] Cross References to Related Applications [0002] To the full extent permitted by law, this U.S. nonprovisional patent application is filed December 31, 2014 and has been assigned serial number 14 / 587,634, entitled "High Dose Output, Through Transmission Target X-Ray System and Methods of Use" Continuation-in-Part of the U.S. Nonprovisional Patent Application, priority and full benefit of which is hereby claimed. technical field [0003] The present disclosure relates generally to X-ray tube technology, and more particularly to X-ray tubes with specific anode, cathode, filament configurations, and material selections to produce high dose X-ray output. Background technique [0004] In many typical states of the art X-ray tubes, the cathode and anode assemblies are hermetically sealed within a glass or metal envelope. Electrons are generated by at least one cathode filament in the cathode assembly. These electrons are accelerated towards the anode assembly by the high...
