Title:
X-RAY HIGH VOLTAGE DEVICE AND X-RAY IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/016310
Kind Code:
A1
Abstract:
In this invention, the influence of noise caused by an X-ray high voltage device is reduced to increase the speed and reliability of communications between each of the units in an X-ray imaging device without increasing the size and the costs of the X-ray imaging device. Provided is the X-ray high voltage device which is applied to an X-ray imaging device wherein X-rays are generated and an image is acquired, the X-ray high voltage device comprising: a converter whereby power supplied from an alternating current power source is converted into a direct current voltage; an inverter whereby the direct current voltage is converted into an alternating current voltage; a high-voltage generator whereby the alternating current voltage is boosted to generate a high voltage; and a control unit controlling at least the inverter. On the basis of the switching timing for the operation of a plurality of semiconductor switching elements provided in the inverter, the control unit outputs communication authorization information indicating whether or not communication is possible between instruments contained in the X-ray imaging device.
