Abstract: front page image
(EN)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.
(FR)L'invention concerne un appareil d'alimentation haute tension et un procédé d'alimentation haute tension de détecteurs de rayons x numériques pour accélérer la séparation de charges ionisées au moment du rayonnement de rayons x. L'appareil d'alimentation haute tension selon l'invention permet d'alimenter en courant haute tension un détecteur de rayons x pour accélérer la séparation et le mouvement de charges ionisées au moment du rayonnement de rayons x; ledit appareil comprend: une source d'alimentation pour produire un courant haute tension; une section détermination de chemin qui fournit un chemin d'alimentation électrique et un chemin de court-circuit qui permet à la sortie de courant de s'appliquer au détecteur de rayons x numérique ou d'être court-circuitée; et un contrôleur de chemin pour sélectionner le chemin d'alimentation électrique ou le chemin de court-circuit. En conséquence, selon l'invention, on peut empêcher un dépassement d'une forme d'onde haute tension, réduire le temps d'acquisition d'image par émission rapide des charges lorsque le courant haute tension est court circuité, et accroître l'uniformité d'une image acquise.
(KO)디지털 X선 검출기에 X선 조사시 이온화되는 전하의 분리를 가속화하기 위한 고전압 전원을 제공하는 장치 및 그 방법이 개시된다. 본 발명의 고전압 전원 제공 장치는, 디지털 엑스선 검출기에 엑스선 조사시 이온화되는 전하의 분리 이동을 가속화하기 위한 고전압 전원을 제공하는 장치에 있어서, 고전압 전원을 출력하는 전원; 상기 전원 출력이 상기 디지털 엑스선 검출기에 인가되거나 단락될 때의 인가 및 단락 경로를 제공하는 경로 결정부; 및 상기 인가 및 단락 경로를 결정하는 경로 제어부를 포함하는 것을 특징으로 한다. 이에 의해 고전압 전원 파형의 오버슈트(overshoot)를 방지할 수 있고, 고전압 전원 단락시 신속하게 전하를 방출시킴으로써 영상 획득 시간을 단축시킬 수 있고, 획득 영상의 균일성(uniformity)을 증가시킬 수 있다.
