Abstract: An apparatus and method for detecting radiation are provided. The apparatus includes an upper electrode layer transmitting radiation; a first photoconductive layer becoming photoconductive upon exposure to the radiation and thus generating charges therein; a charge trapping layer trapping therein the charges generated in the first photoconductive layer; a second photoconductive layer becoming photoconductive upon exposure to rear light for reading out a radiation image; a lower transparent electrode layer charged with the charges trapped in the charge trapping layer; a micro lens layer disposed between the lower transparent electrode layer and a rear light emission unit and including a plurality of micro lenses respectively corresponding to a plurality of pixels; and the rear light emission unit applying the rear light to the second photoconductive layer via the micro lens layer and the lower transparent electrode layer in units of the pixels.

Abstract: 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.

Abstract: 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.
