Classification and application of flat panel detector
Recently, many customers have consulted flat panel detector. Flat panel detector, also known as Dr, is an important imaging equipment equipped with X-ray machine. In addition, it is divided into direct conversion flat-panel detector and indirect conversion flat-panel detector. Recently, many customers have consulted direct flat panel detectors.
The direct flat panel detector consists of amorphous selenium layer, and the storage charge of each transistor corresponds to the dose of incident X-ray. The readout circuit knows the amount of charge at each point and the X-ray dose at each point. Because amorphous selenium does not produce visible light and has no effect of scattered rays, it can obtain relatively high spatial resolution.
