A method and a device for driving high-voltage X ray tube with positive and negative pulses are disclosed comprises a microprocessor unit having a first output port and a second output port, respectively outputting a first and a second timing sequence of control signals, a high-voltage X ray tube, a first high-frequency voltage boost circuit outputting a first regulated high-voltage, a first high-voltage protection circuit, a second high-frequency voltage boost circuit outputting a second high-voltage, and a second high-voltage protection circuit. The first high and the second voltages are respectively, regulated by the first timing sequence of control signal and the second timing sequence of control signal. Both regulated high-voltages are, respectively, inputted to anode and cathode of the high-voltage X ray tube vias the high-voltage protected circuits.

Driving device for driving a high-voltage X ray tube and method thereof driving the same

A handheld X ray device comprises a camera-like X ray generator body having a zoom ring-like object at a front side of the X ray generator body as an exit of X rays and has a collimator section atop a surface of the zoom ring-like object. The camera-like X ray generator body inside has a voltage boosting circuit, an oscillator circuit, a battery, and a control circuit, and a user interface at a real panel of the camera-like X ray generator body. The glass ball-tube is a cold cathode type X-ray generator with a tungsten filament at a periphery of a cold cathode. The voltage boosting circuit, the oscillator circuit, boosting the voltage of the battery up to a predetermined high voltage under controlled of the control circuit assisting by the user interface.

Handheld x-ray device by cold cathode

An encapsulated structure of an X ray generator with a cold cathode and method of vacuuming the same are disclosed. The X ray generator has a glass ball-tube having a base, a tungsten filament, a cold cathode, a focus cap, and an anode target inside, associated with a first electrode pin, a second electrode pin, a single-used pin, and anode pin extended out. The tungsten filament located at the periphery of the base has a first wire end connected with the second electrode pin and a second wire end connected with the single-used pin. While vacuuming the glass ball-tube before melting an end to seal, a voltage is exerting on the single use pin to heat the tungsten, and a high voltage is exerting on the anode target to accelerate the hot electrons emitting from the filament to bombard the inside wall of the glass ball-tube and the anode target so as to shorten the vacuuming time and increase the vacuum level.
