| Question | Answer |
| Indirect DR | two part process, photons are converted to light and light to digital signal |
| Direct DR | incoming x-ray photons are converted to an electric signal |
| What is the base layer of the PSP? | support layer |
| Conductor layer of the PSP does what? | ground the plate and absorb light |
| The light shield layer of the PSP does what? | prevents light from erasing data or decreasing spatial resolution |
