RAD 214 Exam 4 Review

AEC controls what part of the exposure/technique?

• mA

• kVp

• Exposure time

• SID

A change in kVp will cause the exposure time to also change when using AEC.

• True

• False

Tags

NGSS.HS-PS4-3

If you want a long exposure when using AEC you should

• Use a high kVp

• Use the center cell

• Use a high mA

• Use a low mA

The minimum response time is a safety feature that will limit the exposure when using AEC.

• True

• False

______ will increase or decrease the preset exposure values for AEC exposures.

• Back-up time

• Density control setting

• Minimum response time

• Exposure control

What type of technique chart adjusts kV as part thickness changes?

• Variable kVp

• Fixed kVp

• Variable mAs

kVp, mAs, SID, grid/non-grid, and filtration must all be included on a technique chart.

• True

• False

A 1 cm change in part thickness requires kV to change by ___.

• Double

• Triple

• 2 kV

• 1 kV

If part thickness increases by 4-5 cm, mAs should ______.

• increase by 4 times

• increase by 2 times

• increase by 2 mA

• increase by 1 mAs

An AP pelvis measures 30 cm and the lateral measures 35. What should happen to the mAs?

• Increase by 2 mAs

• Increase by 3 mAs

• It should be doubled from the AP view

• Increase by 4 times the AP view.
