Across
- 3. the type of date obtained for DR images
- 4. recognition of this is essential for artifact -free images
- 6. the plot of the histogram has this type of plot
- 8. artifacts: positioning, collimation & backscatter
- 10. techniques used to transmit & archiving large digital image files
- 11. used properly prevents histogram errors
- 14. CR cassettes are very sensitive this
- 19. scratches on the IR require
- 20. as important as collimation
- 21. requires electronic transmission of images
- 22. vendor related cause of artifacts
- 23. can compress to factors up to 100:1.
- 24. digital IRs have artifacts associated with this failure
- 26. fields on the IR needs clear collimated edges & margins
Down
- 1. graph of frequency of occurrence versus digital value intervals
- 2. will be manipulated into for-presentation images
- 5. false visual feature on an image
- 7. artifacts: dust, dirt, scratches
- 9. radiation creates ghost artifacts.
- 12. lossless compression ratio of 3:1 is
- 13. dead pixel or row of pixels will not interfere with this
- 15. assigns a value to a dead pixel based on values of adjacent pixels.
- 16. must select technique & histogram before imaging
- 17. this recording can be saved with lossy compression because fine detail is not required.
- 18. allows reconstruction of the same image
- 25. software correction that equalizes the response of each pixel
