Which type of grid pattern will result in a radiograph with the least amount of primary beam cutoff?

Calculate the new mAs if 15 mAs was originally used with a 16:1 grid and the repeated radiograph will use a 6:1 grid.

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 filtration to 2.5 mm Al 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 generator produces the least amount of IR exposure per mAs?

The distance between the anatomy being imaged and the focal spot is called:

What is the main advantage of the use of a moving grid over a stationary grid?

Which of the following focused grids will allow for the greatest amount of centering and distance lattitude:

If an initial exposure is made using 400 mA, 1/10 sec, 40 mAs, 80 kVp, 50” SID, 12” OID, 8:1 grid ratio, 0.6 mm focal spot and 2.5 mm of filtration, with an 8 x 10 inch field size, and the technologist changes the SID to 60 inches 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

A radiographic technique chart recommends 4 milliampere-seconds (mAs) and 68 kilovoltage peak (kVp) at 72 inches for a certain procedure. How will the receptor exposure be affected if the radiograph is performed using the recommended exposure technique but at 60 inches?
