HIGH-VOLTAGE POWER SUPPLY APPARATUS AND METHOD FOR USE WITH DIGITAL FLAT PANEL X-RAY DETECTORS

摘要

Disclosed are a high-voltage power supply apparatus and method for supplying high-voltage power to digital x-ray detectors to accelerate separation of charges ionized at the time of x-ray radiation. The high-voltage power supply apparatus of the present invention is an appartus for supplying high-voltage power to a digital x-ray detector for accelerating the separation and motion of charges ionized at the time of x-ray radiation, wherein the apparatus comprises: a power source for outputting high-voltage power; a path determination section for providing a power feed path and a short-circuit path to allow the power output to be applied to the digital x-ray detector or be short-circuited; and a path controller for selecting the power feed path or the short-circuit path. Accordingly, the present invention can prevent an overshoot of a high-voltage waveform, reduce image acquisition time by quickly emitting charges when high-voltage power is short-circuited, and increase uniformity of an acquired image.
