Across
  1. 2. Any non- useful contribution to the image which interferes with the visibility of useful information
  2. 4. Geometric unsharpness around the edge of image
  3. 7. Degree of geometric sharpness in the image
  4. 9. sharp edge of shadow
  5. 11. The major controller of image resolution because it controls penumbra (blur)
  6. 12. high frequency= high resolution
Down
  1. 1. Motion: under the direct control of the patient
  2. 3. completely different than “restraints”, which are outside of the scope of a radiologic technologist
  3. 5. Creates false lines on the image of various shapes that not related to anatomy
  4. 6. low frequency= low resolution
  5. 8. Motion: vibrations from the reciprocating grid
  6. 10. ability of an imaging system to convert signals in the to alternating densities or pixel values
