Why must alternating current (AC) be used in the x-ray circuit? -Transformers cannot work without AC -Electrons cannot flow without AC -X-ray tube must have AC to produce x-rays -AC is the only type of current available - Answer -Transformers cannot work without AC AC must be used in the x-ray circuit because transformers cannot work without AC. Rectifiers are used to convert alternating current to direct current before it reaches the x-ray tube. What is the most likely effect ...

what statements are correct regarding the link between radiation and genetic effects - Answer The link has been demonstrated in animal studies. Increased risk to humans cannot be predicted with respect to an individual. The changes in kilovoltage (kVp) will result in the greatest reduction of patient dose, when milliampere-seconds (mAs) is adjusted to compensate for the change - Answer Increase kVp by 30% The following image receptor (IR) system speeds will result in the lowes...
