  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
