Best practice guidelines for the use of automatic exposure control include all of the following except1. set the optimum kV for the body part.2. set the backup timer to 150% of the expected manual exposure.3. set the highest mA station for the focal spot size needed.4. wide collimation will ensure IR coverage.

The exposure indicator number represents all of the following except the

Quantum noise can affect edge discrimination and contrast resolution. The only way to decrease quantum noise is to increase the IR exposure by 1. increasing kV.2. increasing mAs.3. decreasing kV.4. decreasing mAs.

A new high-frequency radiographic system is being released to a customer for first clinical use. The applications person states that the AEC density controls are in 20% increments. If a normal AEC exposure of the hip is 24 mAs, a repeat exposure at +2 would yield a mAs value of
