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

A satisfactory x-ray of the wrist is produced using a technique of 300 milliamperes (mA), 15 milliseconds, 50 kilovoltage peak (kVp), and a source-to-image distance (SID) of 40 inches. How should the mA be changed if the exposure time is decreased to 10 milliseconds?
