Describe the
relationship between blur and visibility of anatomical detail and
small objects.
-
Identify the
principle cause of blurred images in human vision.
-
Identify two
causes of blurred images in photography.
-
Describe at least three
different blur shapes encountered in medical imaging and identify at
least one source for each.
-
Discuss the
concept of equivalent blur.
-
Describe the
relationship between blur and image un-sharpness.
-
Describe the
concept of resolution and how it is expressed (units).
-
Explain how
blurring affects resolution.
-
Explain why
resolution is often used to describe the capabilities of a medical
imaging system or it's components.
-
Describe the general
process of measuring the resolution of an x-ray imaging system.
-
Draw a pair of
modulation transfer function (MTF) curves for two systems which
produce different amounts of blurring.

Explain how a
MTF curve relates to visibility of anatomical detail.
-
Compare the general
blur values and visibility of detail for the different medical
modalities.
