The problem of unequal subject radiographic density is solved by a

During the exposure, the grid in the bucky:

If an initial exposure is made using 800 mA, 0.02 sec, 16 mAs, 70 kVp, 58” SID, 4” OID, 5:1 grid ratio, 0.2 mm focal spot and 3.0 mm of filtration, with a 14 x 17 in field size, and the technologist changes the OID to 8” for a second exposure without changing any other factors, what differences would you expect to see in the second exposure?1) Increased IR exposure2) Decreased IR exposure3) Increased contrast4) Decreased contrast5) Increased spatial resolution6) Decreased spatial resolution7) Increased distortion8) Decreased distortion

Which of the following factors affect beam quantity?

The minimum kVp that requires use of a grid is:

Considering radiographs produced with the following factors, which statement is true?Radiograph ARadiograph B500 mA500 mA0.02 sec0.08 sec36-inch SID72-inch SID

Which of the following collimation settings will demonstrate the most uniform beam intensity within the exposure field?

Kilovoltage peak (kVp) in the x-ray tube is the unit of measurement describing:

All filtration can be expressed in terms of the thickness of

A radiograph is to be made with a 40 inch source-to-image distance (SID) using 12 miliampere-seconds (mAs). If the SID is increased to 72 inches, how could the mAs be changed to maintain the same receptor exposure??
