In computed radiography, what is stored in the cassette to convert X-ray into digital information?

Explanation:
In computed radiography, the cassette uses a layer of photostimulable phosphor to store the X-ray information. When exposed, energy is trapped in the phosphor lattice, creating a latent image. Later, a laser scans the plate and releases that stored energy as light (photostimulated luminescence), which is then detected and converted into a digital image. The other materials listed—silver halide, calcium tungstate, and barium tungstate—serve in conventional film and older screen-film systems, not as the energy-storing element in CR cassettes.
