Precise - pinch of salt, how close values are in a series. Accurate is how close the value is to the actual, correct value. accurate - is how close the value is to the actual, correct value. accurate and precise - graduated cylinder neither accurate nor precise - using different lengths to measure something Isaac Newton - (1665) laid the foundations for classical mechanics, explaining the law of gravity and the laws of motion. Louis Pasteur - (1856) Pasteur contributed greatly towards the...

What are the 2 factors that affect image contrast in diagnostic imaging? - correct answer Intrinsic contrast parameters: are those that cannot be changed because they are inherent to the body's tissues. Ex) Bone density Extrinsic contrast parameters: are those that can be changed because they are under our control. Ex) TR What are examples of intrinsic factors? - correct answer T1 recovery time ...
