A variable kVp-fixed mAs chart is developed for a radiographic unit.  A technique of 100 kVp and 8 mAs is used for a lateral projection of a chest that measures 30 cm in thickness.  If this projection is performed on a chest that measures 20 cm, what new technical factors should be used?

Excess fluid that accumulates in the pleural cavity is termed:

A scratch mark is embedded on a film during the loading process, which results in a lighter area on this area of the film when processed.  This artifact is referred to as a  _____ density on the radiographic image.

Choose the two (2) responses that accurately describe the photographic properties that comprise a radiographic image:

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 3.png

The following AP oblique (frog leg) projection of the right hip was taken on a patient using AEC and the center ionization chamber was chosen. Due to underexposure of the image, which of the detector configurations below would be optimal in producing an image with adequate density? (Hint, the underexposed segment of the image is on the left side of the image) frog leg hip.jpg

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?
