Why does a CMOS digital X-ray detector have less image blooming than other detectors?

In conventional detectors, image blooming occurs when individual pixels in the detector are over-driven by direct radiation to the pixels. This happens because the pixels deliver their signals to the electronic amplifiers in a “bucket brigade” along each row and column. When one or more pixels are over-driven, the signals from all other pixels in that row and column can be affected causing blooming or streaks in the observed x-ray image. CMOS digital X-ray detectors eliminate this problem because each pixel is amplified separately at each pixel and as a result their signals do not affect signals from adjoining pixels.
