Saturn says the 2004 Vue can accelerate from 0 to 60 mph in just 7 seconds, which is pretty quick (and about 1.5 seconds quicker than the 2003 model). Yet EPA fuel economy ratings remain unchanged (19/25 mpg for the AWD V6). Variable-valve timing enhances high-end power, low-end torque and fuel economy.
Using a noise threshold of 20 HU and a dose threshold of 2.5 cGy, a range of imaging parameters was established for each circumference from which technique optimization curves were created to determine optimal mAs and kVp pairs.The mean measured dose was 2.435 Â± 0.019 cGy. The mean measured noise was 29.35 Â± 1.45 HU.BJECTIVE: The objective of our study was to determine the effect of mAs and kVp reduction on pediatric phantoms based on patient circumference to optimize dose reduction and maintain image quality for abdominal CT.
