Describe the main applications of each of the main imaging modalities.
Give ballpark figures for the resolution of each of the main imaging modalities.
How are CT images reconstructed?
How would you explain the effect of the width of a smoothing kernel in terms of spatial frequency? i.e. would a wide smoothing kernel effect the low or high spatial frequencies in an image?
Why do higher kV images have more noise?
What do you mean by statistical fluctuations in an image?
What factors affect the resolution of an x-ray image?
Why do we add copper filters to an x-ray beam?
What is the effect of adding copper filters on the x-ray image quality?
How useful do you think the software you used was? Discuss the errors of the software (project work)
What range of contrast levels does the CDRAD test object mimic clinically? (project)
What does DICOM stand for? What is a DICOM image, what information is contained within the image header?
