The following statements with regard to the spatial resolution in a DR system are true except
1)DR systems have spatial resolution capabilities of approximately 3.7 lp/mm.
2)spatial resolution is affected by the size of the DELs and the spacing between them.
3)changing the size of the exposure field (collimation) does not affect spatial resolution.
4)as the DELs become larger, the spatial resolution capability increases.
A) 1 only
B) 1 and 2 only
C) 1, 2, and 3 only
D) 1, 2, and 4 only

Question

Quizplus · Accepted Answer

Statement 1 is false. DR systems have spatial resolution capabilities beyond 3.7 lp/mm. Statement 2 is true. Statement 3 is false. Changing the size of the exposure field affects spatial resolution as it can affect the number of DELs within the field. Statement 4 is false. As the DELs become smaller, the spatial resolution capability increases.
