Switching from 400 RS to 200 RS typically results in

Explanation:
Lowering the screen speed rating from 400 RS to 200 RS makes the imaging screen slower. Slower screens emit less light per exposure and have less lateral light spread, which reduces geometric blur and sharpens fine details. That sharpening means higher spatial resolution. There’s a trade-off, though: the slower screen usually requires more exposure to achieve the same image brightness, which tends to increase the patient dose.
