Across
- 2. Columns and rows of pixels

- 7. The efficiency of an IR in converting the x-rays it receives into a quality image
- 8. The level of contrast resolution compared to the amount of noise in a digital image
- 9. The amount of radiation the IR received
- 11. When you view your image on film
- 12. Blackens out the white collimation borders
- 13. Performed by the Radiologist or Technologist
- 17. Controls brightness
- 20. Number of bits within a pixel
