For example a chest, when I was at a hospital using cr we did an average chest at 80@20 whereas a newer machine at a different hospital performed better with 110@1-2. Both were in range.

WebbIn a second series of experiments, the tube voltage was varied between 50 and 100 kVp, and the mAs adjusted to maintain a constant exposure level at the input of the image intensifier. At a constant x-ray tube voltage, the surface dose and energy imparted were directly proportional to the input exposure per frame used to acquire the DSA images. Webb1 juni 2002 · Statistical analysis of imaging performance characteristics found for mammography units operated at 25 and 26 kVp. The data relating to mAs show that the required value at 26 kVp is about 15% lower than that at 25 kVp. The range of mAs used to generate a phantom image is from to mAs.

WebbIncrease the kVp and increase mAs to reduce noise To increase the effective mAs, decrease the gantry rotation. In MDCT scanners with automated tube current modulation, changing the scanner from “Fixed mAs” to “Automatic mAs” will allow the scanner to determine the amount of mAs to deliver per body section.
