Abstract
The X-ray generator includes a booster for boosting a first DC voltage supplied from a voltage source to a second DC voltage higher than the first DC voltage, at least one capacitor for receiving the second DC voltage and generating a charging voltage on the basis of the second DC voltage, a converter for converting the charging voltage into a driving voltage, an X-ray source for receiving the driving voltage and emitting X-rays according to the driving voltage, and a controller for controlling the booster, the converter, and the X-ray source. The controller calculates a cooling time required for cooling the X-ray source to a predetermined temperature or lower, determines the magnitude of the second DC voltage according to the cooling time, and applies the second DC voltage to the capacitor for the cooling time.
Claims6
An X-ray generator comprising:
- a booster configured to boost a first DC voltage supplied from a voltage source to a second DC voltage that is higher in magnitude than the first DC voltage;
- at least one capacitor configured to receive the second DC voltage and to generate a charging voltage;
- a converter configured to convert the charging voltage into a driving voltage;
- an X-ray source configured to receive the driving voltage and to emit X-rays;
- and
- a controller configured to control the booster, the converter, and the X-ray source,
- wherein the second DC voltage is variable, and
- the controller calculates a cooling time that is taken for the X-ray source to be cooled to below a predetermined temperature after the X-ray source emits X-rays, determines the magnitude of the second DC voltage according to the cooling time, and applies the second DC voltage to the capacitor for the cooling time.
