Title:
RADIATION IMAGE PICKUP DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/064640
Kind Code:
A1
Abstract:
Prior to read out of a signal charge from a pixel array of an X-ray plane detector, leak signal information is acquired by seeking the signal charge. When performing X-ray image pickup by continuous visualization using a radiation image pickup device, even if excessive X-rays are incident directly to a part of pixels of the X-ray plane detector such as halation by X-rays, the artifact caused by it is eliminated to obtain a correct X-ray image, so that an observer can easily read the picked up image.
