What are the 3 things radiographers can do to control motion? Be specific in your responses.

With all other factors unchanged, if SID is increased, exposure to the image recptor will: 

Elongation of spherical anatomy can occur with off-centering of the part, but to a lesser extent than off-angling of the tube.

What is the relationship between SID and magnification?

To minimize the effect of motion on the image, exposure time should not exceed: 

When more than one ionization chamber is used, the signal is: 

A radiographer receives 24 mSv of radiation at a distance of 4 feet, what dose will the radiographer receive at 7 feet?

What effect does severe motion have on subject contrast? 

You must perform a lumbar spine on an average-sized patient. The AP had a satisfactory exposure at 20 mAs. What technique should be used for the lateral projection?

A change in what factor can effectively increase spatial resolution, decrease image magnification, increase the field of view without changing IR size, and decrease patient exposure?
