A satisfactory x-ray of the thoracic spine is made at 60 inches using automatic exposure control. The exposure time was 100 milliseconds. If the exam is repeated at 40 inches, what will the new exposure time be?

Which one of these is the major factor for controlling size distortion?

At higher kVp settings, the radiographic image will demonstrate:

In the broadest sense, anything that impedes full visibility of the details in an image may be classified as:

What is the result of increased matrix size if field of view remains the same?1) decreased pixel size2) increased spatial resolution

The main advantage involved with the use of a radiographic grid is:

Which of these changes will improve the spatial resolution recorded in the radiographic image?

Which situation is most likely to result in grid errors?

Placing filtration in the path of the beam results in:

An x-ray exposure is made using 96 kilovoltage peak (kVp) and 3 milliampere-seconds (mAs). What new technique will result in the greatest decrease in patient dose?
