Adjustments in kVp should be used to control radiographic

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 exposure time to 0.04 sec 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

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

Calculate the new  mA  required to maintain the same IR exposure produced with the original values.

If the OID is 8 inches and the SID is 72 inches, what is the magnification factor?

During the exposure, the grid in the bucky:

The central ray is located in the center of the:

A compensating filter is used to create ________ optical density with a body part of _________ thickness.
