Flat panel detectors can be divided into two types according to their luminescent materials: CSI and GDS. The image of CSI is clearer, and the sensitivity of GDS is higher.
If flat panel detectors are classified according to the semiconductor of the conversion material, there are two common ones, one is the flat panel detector of amorphous selenium, and the other is the flat panel detector of amorphous silicon. Amorphous selenium flat panel detectors have high sensitivity and are usually used for dynamic flat panel detectors. Amorphous silicon flat-panel detectors are conducive to storage and relatively low cost. In addition, the load-bearing capacity of the flat panel detector is generally 300KG, and the service life is generally 3-5 years.
