Exam 10: Radiographic Exposure Technique

If a film image has to be repeated because of a positioning error,what should be done if the density was just a little too much?

Whenever magnification is increased:

Using excessive kVp with a digital IR results in:

What mA should be selected to produce 32 mAs using a 0.04 exposure time?

If 400 mA @ 0.03 s produces a film image of a knee that is just a bit too light to see the bony structure,the exposure factors should be changed to:

If a film image appears dark,to produce a diagnostic image you may decide to:

If the intensity of radiation at 72 inches is 225 mR,what is the intensity if the SID is decreased to 40 inches?

Using a grid to reduce scatter radiation reaching the film-screen IR results in:

Increasing collimation means decreasing the x-ray field size.

Exposure factors that include higher kVp and lower mAs are recommended for both film and digital imaging to reduce patient exposure.

A magnification of factor of 1 cannot be achieved with radiographic imaging.

The ________________ body habitus accounts for approximately 50% of the adult population.

Which of the following results in increased scatter radiation reaching the IR?

The optimal kVp for digital image receptors should be _________ than that for film-screen image receptors.

The relationship between kVp and the quantity of remnant radiation is known as the:

As the SID increases,the x-ray photons in the beam become less perpendicular to the object being imaged.

Which of the following is the correct formula to determine how mAs should be adjusted when different ratio grids are used?

Which of the following has an effect on how much mAs is used for a specific examination?

With digital imaging,if the image receptor is not exposed to enough radiation:

Assuming that all of these produce a similar amount of exit radiation,which of the following exposure factors minimize the radiation dose to the patient?
