QuestionAnswer
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
