Question

A ____ produces an electric signal when struck by photons.

Answer 1

What is hard wired, cassetteless and the detectors are permanently enclosed inside a rigid protective housing

Digital radiography

Consist of a photoconductor such as amorphous selenium (a-Se), which converts the x-ray photons directly into electrical signals.

This category also includes silicon and CCD detectors.

Flat panel detectors

What is a kind of flat panel detectors that consist of a photoconductor

Amorphous selenium (A-Se),

Holds a charge on its surface that can then be read out by a TFT

Direct capture detectors
