摘要:
In one embodiment, a digital X-ray detector is provided with a plurality of pixel regions. Each pixel region includes a first photodiode having a first area and a second photodiode having a second area equal to or smaller than the first area. The digital X-ray detector also includes a shielding structure that overlies the first and second photodiodes of each pixel region with the shielding structure shielding proportionally less of the first photodiode than of the second photodiode to provide the first photodiode with a first sensitivity and the second photodiode with a second sensitivity lower than the first sensitivity.
