Abstract (en)
[origin: WO2022235985A1] A through transmission-ray system with electron manipulation and accompanying methods of use are disclosed. The system may include an x-ray tube for accelerating influenced electrons under a high voltage potential for the purpose of irradiating samples. The x-ray tube may include an evacuated and vacuum sealed housing, a through transmission target anode deposited on the housing, a filament within the housing, and a cathode structure for facilitating manipulation of emitted electrons using a waveform generator, electrostatic poles, lenses, radio frequency signals, and/or magnetic fields. The cathode structure may emit electrons toward the target anode and may facilitate electrostatic and/or magnetic influence of the emitted electrons to generate a plurality of x-ray field shapes and/or patterns. Additionally, the cathode structure may be utilized to adjust the electron trajectories of the electrons to optimize irradiation of samples within range of the x-ray tube depending on the relevant use-case scenario.
