APPARATUS FOR DETECTING X-RAYS AND METHOD OF OPERATING THE SAME
First Claim
1. A method for driving an X-ray detecting apparatus, comprising:
- sampling a first data voltage corresponding to a rheobase voltage and a bias voltage, said rheobase voltage being generated by a current from a photodiode;
sampling a second data voltage corresponding to the bias voltage after resetting the rheobase voltage; and
resetting the rheobase voltage from the time that the sampling of the second data voltage is finished to the time that a corresponding frame is finished.

Abstract
An apparatus for detecting X-rays and a driving method of the X-ray detecting apparatus. The driving method includes sampling a first data voltage corresponding to a rheobase voltage and a bias voltage, the rheobase voltage being generated by a current from a photodiode, sampling a second data voltage corresponding to the bias voltage after resetting the rheobase voltage, and resetting the rheobase voltage from the time that the sampling of the second data voltage is finished to the time that a corresponding frame is finished. An image delay generated when an X-ray motion picture is displayed may be minimized.

5. An X-ray detecting apparatus, comprising:
-
an X-ray receiving panel including a photo-detecting pixel; a data detector detecting a data signal from which noise is removed from a signal output from the X-ray receiving panel through noise sampling; and a reset driver applying a reset signal to the photo-detecting pixel, said reset signal resetting a rheobase voltage generated by the photo-detecting pixel for the noise sampling, the reset driver applying the reset signal after detecting the data signal from which the noise is removed in the data detector until the time that a corresponding frame is finished. - View Dependent Claims (6, 7, 8, 9, 10, 11)
