Which of the following best describes the sequence of events in a direct digital flat panel detector?

X-rays captured, electrical signal generated, storage of electrical signals, image displayed on computer.

What is a characteristic feature of Charge Coupled Devices (CCD) when utilized in non-flat panel detectors?

Converts light to electrical signals

What does the 'fill factor' in a digital pixel represent?

The percentage of surface area that senses the incoming signal

What is the role of a thin film transistor (TFT) in the process depicted in the diagram?
