A radiographic exposure of a humerus is made using 65 kVp and 8 mAs.  Another exposure is made on the same part using 75 kVp and 8 mAs.  Which of the following changes in contrast and density will result as a change of exposure factors?

The radiopaque material in a grid is made of:

List, in order, the steps of the latent image formation according to the Gurney-Mott theory. Repetition of the process deposits several silver atoms at the sensitivity speck. An ion absorbs an x-ray/light photon and frees an electron. The silver ion neutralizes at the sensitivity speck.  The freed electron is trapped at the sensitivity speck, giving it a negative charge. The negatively charged sensitivity speck attracts a free silver ion.

Which of the following conditions will decrease radiographic density?

Which type of body habitus occupies 35% of the adult population?

Which of the following is a current general rule that is used for the backup timer in an AEC unit?

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:
