Exam 4: Exposure Technique Factors

The property of the x-ray beam that impacts the unsharpness on the radiograph is beam:

Film-screen images should be produced with very high kVp and very low mAs in order to reduce patient exposure.

The SOD can be determined by:

In order to see the effect of changing kVp, a greater change is needed when operating at low kVp as compared to high kVp.

Which one of the following immobilizing devices requires an increase in the exposure technique?

Which of the following contrast media do not require an adjustment in exposure factors?

With all other factors remaining the same, a patient with which body habitus would require the highest exposure factors?

Knowing that 6 mAs is appropriate for a knee examination done at 40" SID, how much mAs should be used at 56" SID?

Which of the following mA and exposure time combinations does not produce 12 mAs?

With film-screen imaging, for a given exposure technique, increasing part thickness decreases radiographic density.

When choosing a grid for an examination, the grid with the highest grid ratio should always be selected in order to most improve image contrast.

Using a small focal spot size may be prohibited due to the:

The digital imaging exposure indicator reflects the amount of radiation:

If the first radiograph of a chest is done using 72 inches and 12 mAs, and a second radiograph is done using 40 inches, how much mAs should be used to maintain exposure to the IR?

When a film-screen image needs to be repeated because it is too dark, the minimum change in mAs needed is:

Generally speaking, what do additive pathologic conditions require?

Changes in kVp do not affect the digital exposure indicator.

With film-screen imaging, which of the following technique factors will produce an image with the greatest density?

With film-screen imaging, what is the primary controller of image contrast?

When the SID is divided by the SOD, what is the result called?
