Each of the following results in image unsharpness EXCEPT one. Which one is the EXCEPTION?
A) Patient movement during exposure
B) Image receptor positioned close to the teeth
C) A short PID
D) The use of intensifying screens

Quizplus · Accepted Answer

Image receptor positioned close to the teeth is the exception because positioning the image receptor close to the teeth actually helps in reducing image unsharpness by adhering to the principle of geometric sharpness, which states that the closer the image receptor is to the object being imaged (in this case, the teeth), the sharper the image will be. This is in contrast to the other options, which all can contribute to image unsharpness.
