The correct method to subtract background ROI counts from organ ROI counts is by
Which type of ROI creation method is best suited for a MUGA study with poor red blood cell labeling?
Spatial smoothing may not be effective at the image frame edges because:
pixels at the edges are not completely surrounded by other pixels
Negative value kernels' are used in:
edge enhancement filters.
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
The ability to detect small changes in radiopharmaceutical distribution over time is called:
All of the following are other terms for smoothing filter,
- filter function
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
How is image contrast affected with spatial smoothing:
spatial smoothing decreases contrast
Automatic edge detection method can be used for getting count statistics in all of the following types of studies, EXCEPT:
'Negative value kernels' are used in:
edge enhancement filters
