Abstract
The present invention discloses a radiation detector, an imaging device and an electrode structure thereof, and a method for acquiring an image. The radiation detector comprises: a radiation sensitive film, a top electrode on the radiation sensitive film, and an array of pixel units electrically coupled to the radiation sensitive film. Each pixel unit comprises: a pixel electrode (which is configured to collect a charge signal in a pixel area of the radiation sensitive film), a storage capacitor, a reset transistor, a buffer transistor, a column strobe transistor, and a row strobe transistor. The column strobe transistor and the row strobe transistor are connected in series between the buffer transistor and the signal line, and transfer the voltage signal of the corresponding pixel unit in response to a column strobe signal and a row strobe signal. The radiation detector may be used for, for example, X-ray digital imaging.
