List, in order, the process that occurs in an AEC ionization chamber device:Freed electrons are attracted to anodeTimer terminates exposureIon chambers are ionizedRadiation exits the patient

List the stages of development for a technique chart: Extrapolate the technique chart Establish a quality control program for each machine Perform limited clinical trials on patients Produce initial phantom images with various kVp and mAs settings Review and select the best phantom image Periodically review chart for accuracy Perform additional phantom images for small, medium, and large part thicknesses

A PA chest on an adult patient is ordered and the technologist uses AEC for the exposure selecting the wall bucky.  The technologist makes an error on the console when setting up for the examination and selects the table bucky by mistake and continues with the exposure.  Which of the following will occur due to this error?

Refer to the following technique table and determine the adjustment in mAs needed for the change in part thickness: Technique Chart for mAs 3.png

Which of the following accurately describes the mA and exposure time when using an AEC system?

The MRT for modern AEC units is:

An AP hip radiograph is performed using an AEC unit and the radiographer chooses the central detector.  What may result if the radiographer positions the central ray on the lateral aspect of the hip on the patient’s soft tissue instead of over the bone?

Identify each of the following disease processes as an additive or destructive condition.  Responses may be used more than once. 

Using a base of 40, how much kVp is needed to establish a baseline for a knee that measures 13 cm in the oblique projection?

Refer to the following technique table and determine the adjustment in kVp needed for the change in part thickness using the kVp/cm rule: Technique Chart for kVp 2.png
