An acceptable radiographic image is taken under the following conditions: single phase-2p, 400 mA, 75 ms, 1.2 mm fs, 82 kVp, 44" SID, 400 RS receptor, 8:1 grid.
What change would need to take place with the exposure conditions below, in order to maintain image quality?
HF generator, 1.0 mm fs, 94 kVp, 44" SID, 300 RS receptor, 12:1 grid
A)Change the exposure to 300 mA , 46 ms.
B)Switch to a RS 200 receptor with no compensation.
C)Change to 20 mAs.
D)Decrease the SID to 40" with no compensation.

Switching from a single-phase generator to a high-frequency (HF) generator increases the efficiency of x-ray production. To maintain image quality with the changes listed (HF generator, 1.0 mm focal spot, 94 kVp, 44" SID, 300 RS receptor, 12:1 grid), adjusting the exposure to 300 mA and 46 ms compensates for the increased efficiency and the other changes in conditions, ensuring the image quality remains consistent.
