The flashcards below were created by user certifiedfly on FreezingBlue Flashcards. What would you like to do?


  1. The correct method to subtract background ROI counts from organ ROI counts is by
    area normalization
  2. Which type of ROI creation method is best suited for a MUGA study with poor red blood cell labeling?
    manual method
  3. Spatial smoothing may not be effective at the image frame edges because:
    pixels at the edges are not completely surrounded by other pixels
  4. Negative value kernels' are used in:
    edge enhancement filters.
  5. A graph of counts along a line drawn through an image which demonstrates how counts rise and fall in the structure is called
    a count profile
  6. The ability to detect small changes in radiopharmaceutical distribution over time is called:
    temporal resolution
  7. All of the following are other terms for smoothing filter,
    • kernel
    • filter function
    • mask
  8. A NMT places a box telling the computer where the left ventricle is located in a MUGA study. The computer then generates the left ventricle volume curve from the identified area. The ROIs created in this case is an example of:
    Automatic edge detection method
  9. How is image contrast affected with spatial smoothing:
    spatial smoothing decreases contrast
  10. Automatic edge detection method can be used for getting count statistics in all of the following types of studies, EXCEPT:
    STATIC
  11. 'Negative value kernels' are used in:
    edge enhancement filters
