Exam 4: Exposure Technique Factors

With film-screen imaging, what would be the appropriate change in mAs if the kVp were decreased by 15% and the density needed to be maintained?

With film-screen imaging, which of the following changes will result in increased density with no change in contrast?

The misrepresentation of the size of an object is:

Assuming all produce appropriate density images, which of the following would be the best exposure technique choice when performing a chest radiograph on an infant?

With digital imaging, using twice as much mAs as needed will result in an image with _______________ brightness and _________________ patient exposure.

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 minimum change in mAs that would result in a visible change in radiographic density?

With film-screen imaging, an abdomen image is done using 60 kVp and 30 mAs.Image density is appropriate, but the image has too high (short scale)contrast.Which of these exposure factors would be the best change to make?

Once the part has been penetrated, a doubling of the mAs results in ____________ the exposure to the IR.

Any increase in magnification results in a decrease in recorded detail.

For film-screen imaging, density is controlled by:

With digital imaging, the same mAs and kVp should be used for an AP lumbar spine and a lateral lumbar spine.

As compared to a three-phase x-ray unit, a single phase unit requires higher exposure techniques to produce a comparable image.

With film-screen imaging, decreasing collimation (using a larger field size)results in ____________image contrast and ____________ patient exposure.

The radiographic grid is located:

Which of the following is a destructive pathology?

If the first radiograph of a foot is done using 4 mAs at 40 inches, and a second radiograph is done using 50 inches, how much mAs should be used to maintain exposure to the IR?

With film-screen imaging, increasing the kVp results in an image with ___________ density and ____________contrast.

If a person stands 3 feet from the source of exposure, receives an exposure of 160 mR, and then moves to 6 feet from the source of exposure, what would be the new exposure according to the inverse square law?

Increasing tube filtration results in an x-ray beam with __________________ quantity and ___________ energy.
