Answers
What is an artifact in medical imaging? - Correct Answers
✅Any false visual feature on a medical image that can
simulate or obscure tissue.
How can artifacts affect medical diagnosis? - Correct
Answers ✅Artifacts interfere with diagnosis and should be
avoided.
What are the three categories of artifacts in digital
radiography? - Correct Answers ✅Image receptor artifacts,
software artifacts, and object artifacts.
What can cause image receptor artifacts? - Correct
Answers ✅Rough handling, scratches, or dust on the image
receptor.
How can dust artifacts be corrected? - Correct Answers
✅By proper cleaning of the image receptor.
What happens to image receptors that demonstrate artifacts

Answers
What is a ghost image in radiography? - Correct Answers
✅An incomplete erasure of a previous image on a CR image
receptor.
How can ghosting artifacts be corrected? - Correct Answers
✅By additional erasing of the CR with the CR reader.
What is preprocessing in digital radiography? - Correct
Answers ✅Manipulations of output data of an image
receptor to correct for potential artifacts before image
processing.
What is flatfielding? - Correct Answers ✅A preprocessing
software correction to equalize the response of each pixel to
a uniform x-ray beam.
What is the impact of background radiation on CR imaging
plates? - Correct Answers ✅It can produce an image on a
CR imaging plate that had not been used for several days.
What are the two types of image compression techniques? -
Correct Answers ✅Lossless and lossy compression.
