Unformatted text preview: _________ A certain technique calls for 135 kVp, 45 mAs, which results in an x-ray intensity of 30 mR at the position of the patient. If the x-ray intensity decreased to 20 mR, what is the new kVp? ___________ Distance A certain technique calls for 100 kVp/20 mAs at a SID of 150 cm. The exposure at that the image receptor is 15 mR. If the same technique is used at a SID of 110 cm, what will be the x-ray exposure? ___________ A certain technique calls for 120 kVp/35 mAs at a SID of 125 cm. The exposure at that the image receptor is 18 mR. If you need an exposure of 8 mR, where must the patient be placed? _____________...
