Question | Answer |
---|---|
1. What is the purpose for the breadbox in digital radiography? | read the image stored on the storage phosphor receptor and convert it to an image that can be viewed on the computer monitor |
2. Describe the CCD. | thick, black, rigid plastic piece about the width and length of an intraoral film; cord extending from it to the computer; contains a chip imbedded in silicon and electron wells for storing the latent image |
3. What type of digital radiography is associated with the CCD? | direct digital imaging |
4. What type of digital radiography requires a scanner? | indirect digital imaging (film radiographs are scanned and converted into computer images) |
5. What type of digital radiography is associated with a cassette that must be read by an optical scanner? | storage phosphor imaging |
6. Can a storage phosphor image receptor be reused? | yes - it is exposed to light to discharge the stored image and ready it for re-exposure |
7. How is cross contamination prevented when using a CCD? | plastic sleeve barrier placed over the CCD and down the cord |
8. How is cross contamination prevented when using storage phosphor image receptors? | receptors are placed into sealed plastic barriers |
9. True or false: The cost of digital radiography systems is considered an advantage. | false |
10. True or false: The sensor is guaranteed to last forever. | false |
11. True or false: It is illegal to enhance the digital image for easier patient interpretation. | false |
12. True or false: The color of the digital radiographic image can be changed using software. | true |
13. What exposes the film in digital radiography? | x-ray |
