Answer to Question 1

asthenic body types

Rationale: Increased technical factors should be considered when imaging involves casts, larger patients, and patients with additive pathologies. In addition, technical factors should be increased after a patient has received positive contrast agents such as barium or injectable contrast media.

Answer to Question 2

photocell

Rationale: A breathing technique is set manually. AEC cannot be programmed for a predetermined length of exposure. The technologist will set the kVp, a lower mA station, and a time of approximately 3-4 seconds.
