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 to a 12:1 grid ratio 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 digital imaging system that requires the use of lenses or optical coupling systems is:

All other factors equal, when mAs is reduced, the photoelectric/Compton ratio will:

Focal spot blur can be reduced by using __________.

All factors remaining constant, which of the following set of exposure conditions would yield an image with the GREATEST IR exposure?

A radiograph of the shoulder is produced using 12 milliampere-seconds (mAs) and 75 kilovoltage peak (kVp) at the wall bucky. How could the technique be changed to decrease contrast while maintaining the same receptor exposure?

A radiographic image is produced using 20 mAs and 74 kVp. Which of the following are likely to occur on a second radiograph taken with 15% increase in the kVp value?

A radiograph is taken at 400 mA, 55 ms, 95 kVp. A second image could be taken to improve contrast  at

A radiographic technique chart recommends 30 milliampere-seconds (mAs) and 85 kilovoltage peak (kVp) at 40 inches for a certain procedure. How will the receptor exposure be affected if the radiograph is performed using the recommended exposure technique but at 50 inches?

Higher radiation exposures will result in:
