Image Quality — Quiz
Test your understanding of image quality with 5 practice questions.
Practice Questions
Question 1
Which artifact appears as a grainy or speckled pattern on a radiograph due to insufficient photon quantity reaching the detector?
Question 2
Which term describes the range of exposure values that yield acceptably diagnostic optical densities on a radiographic receptor?
Question 3
If the source-to-image distance (SID) is decreased from 100 cm to 50 cm while keeping object position and exposure factors constant, what happens to image magnification?
Question 4
In an X-ray setup with SID = 120 cm and OID = 15 cm, calculate the magnification factor (MF).
Question 5
On a digital radiograph, increasing the window width (WW) while keeping window level constant will primarily:
