Category: Image Production-19An exposure was made at 40-in. SID using 300 mA, 0.12-second exposure, and 70 kV with a 200 RS combination and an 8:1 grid. It is desired to repeat the image, and, to produce improved detail, use 48-in. SID and 100 RS combination. Using 0.25-second exposure, and with all other factors remaining consistent, what mA will be required to maintain the original radiographic density?
