Publication number: 20110261925Abstract: A grid apparatus of an X-ray detecting apparatus is provided. The grid apparatus includes an X-ray absorbing material for absorbing X-rays that are scattered from an object, and an X-ray passing material formed between the X-ray absorbing materials to allow X-rays to pass therethrough. The X-ray absorbing material and the X-ray passing material form a line pattern forming a predetermined angle with a line pattern of pixels of an X-ray detector. The grid apparatus enables simpler implementation of a grid noise reduction algorithm and reduces the time and labor for reducing grid noise.Type: ApplicationFiled: October 4, 2010Publication date: October 27, 2011Applicant: DRTECH CorporationInventors: Dong-Sik KIM, Sang-Gyun LEE, Beom-Jin MOON, Jung-Kee YOON

Publication number: 20110062342Abstract: Provided are a high-voltage power supply apparatus and method for supplying high-voltage power to a digital flat panel X-ray detector to accelerate the separation of charges ionized upon the irradiation of the digital flat panel X-ray detector with X-rays. The high-voltage power supply apparatus includes a power source outputting high-voltage power; a path determiner providing a supply path for supplying the high-voltage power to the digital flat panel X-ray detector and a short-circuit path for short-circuiting the high-voltage power; and a path controller determining the supply path and the short-circuit path. Therefore, it is possible to prevent an overshoot of the waveform of the high-voltage power. In addition, it is possible to improve the uniformity of a radiation image and reduce the time taken to obtain a radiation image by quickly discharging charges when the high-voltage power is short-circuited.Type: ApplicationFiled: May 7, 2009Publication date: March 17, 2011Applicant: DRTECH CorporationInventors: Sang-il Lee, Beom-jin Moon, Jung-kee Yoon
