What is the size of an object radiographed at a 60 inch SID and a 6 inch OID if the image measures 5.5 inches?

A satisfactory radiograph is performed using 75 kVp and 18 mAs. If the kVp is decreased by 15% but the mAs remains constant, what changes will the image demonstrate? Decreased density Increased density Decreased contrast Increased contrast

Which of the following increments in OD indicates a doubling or halving in opacity?

The primary controlling factor of contrast is:

The product of mA and exposure time is equal to ____.

The heavy black densities produced on a radiographic image after processing correspond to what region of the characteristic curve?

A ____ is a device designed to expose the film to a reproducible, uniform light through a series of progressively darker filters or optical step wedges.

OID is related to recorded detail in which of the following ways?

The mA station is changed from 300 mA to 150 mA.  Which of the following changes in the x-ray beam will occur?

A radiographic image is taken of a lateral femur using 80 kVp and 10 mAs that demonstrates insufficient density.  In using the 15% rule, which of the following changes should be made for the second exposure in order to achieve an acceptable radiograph?
