The present inventive concept provides a method for manufacturing a filament including the steps of inserting and bonding an electrode having a desired length into a through-hole of a plate-shaped base to form a first part; bonding a wire having a desired length to one surface of a plate-shaped disc to form a second part; and bonding the electrode of the first part and the wire of the second part to form a filament, a filament manufactured by said method, and an X-ray tube having said filament.

Method of manufacturing a filament, filament manufactured thereby, and x-ray tube having the filament

The present inventive concept provides a voltage generating apparatus for X-rays including a console that receives an X-ray irradiation signal to generate a control signal and detects the X-ray irradiation signal to generate a first detection signal, a pulse control unit that receives the control signal and the first detection signal from the console to generate a second detection signal and generates a pulse signal according to the control signal and the second detection signal, and a high voltage generating unit that generates a high voltage according to the pulse signal from the pulse control unit, and an X-ray generating apparatus having the same.

Voltage generating apparatus and x-ray generating apparatus having the same

According to the present inventive concept, there is provided an X-ray generating apparatus including a voltage generating apparatus that generates a pulse signal according to an X-ray irradiation signal and generates a predetermined voltage according to the pulse signal, and an X-ray tube that generates X-rays according to the voltage from the voltage generating apparatus, wherein the voltage generating apparatus detects arc discharge by detecting a current of the X-ray tube.

X-ray generating apparatus

Disclosed herein is a dual energy X-ray imaging apparatus. The dual energy X-ray imaging apparatus includes: an X-ray generator configured to generate a predetermined dose of X-rays; an X-ray detector configured to detect the X-rays received from the X-ray generator; an X-ray filter located between the X-ray generator and the X-ray detector, and configured to filter out part of the generated X-rays so that X-rays of two dose types reach the X-ray detector; and a medical image processing unit configured to generate medical images corresponding to the two dose types recognized by the X-ray detector.

Dual energy X-ray imaging apparatus

Provided is a miniaturized X-ray tube including an extractor and provides a miniaturized X-ray tube including a filament that emit electrons if a voltage is applied, a base having two filament through-holes for fixing the filament and for connecting power to both electrodes of the filament, a cylindrical extractor in close contact with the base and surrounding the filament without being in contact with the filament, a cutoff voltage providing unit configured to apply a cutoff voltage between one electrode of the extractor and one electrode of the filament, a body that is formed of a ceramic material, surrounds the extractor, and includes one end in close contact with the base, and a target that is connected to the other end of the body, receives the electrons emitted from the filament, and emits X-rays.
