ARTIFACTS Questions and Answers (Top
Grade Assured) 2026 Update
Digital Radiographic Artifacts - Correct Answers
✅•Software artifacts
•
•Image receptor artifacts
•Object artifacts
Image receptor artifacts - Correct Answers ✅•Rough
handling
•Scratches
•Dust
•Residual glue on imaging plate
•Pixel malfunction
•Ghost image
Ghost image - Correct Answers ✅•Incomplete erasure of a
previous image on a CR Imaging plate.
•Severely over exposed imaging plate might requires two
cycles of erasing.
•If a CR IP has not been used for 24 hours, it should be
erased again before use.
Software artifacts - Correct Answers ✅•Dead pixels

ARTIFACTS Questions and Answers (Top
Grade Assured) 2026 Update
•Dead rows or columns of pixels
•Failure of electronic preprocessing can cause uninterpretable
images.
•Bushong Figure 21-7
Interpolation - Correct Answers ✅•A correctional algorithm
•
•A mathematical process of assigning a digital value to a
dead pixel based on recorded values of adjacent pixels.
Irregular patterns - Correct Answers ✅•Irradiation of digital
radiographic image receptor by the raw x-ray beam may
show variations in density(brightness) over the image.
•Flatfielding can minimize the effect of irregular patterns.
Flatfielding - Correct Answers ✅• is a software correction
that is performed to equalize the response of each pixel to a
uniform x-ray beam.
•A preprocessing manipulation
•Ensures a uniform response on the pixels.
Compression artifacts - Correct Answers ✅•Transmitting
and archiving of large data is difficult.
