Technical considerations for abdominal imaging of obese patients include all of the following 1. increasing kV will increase the penetrability of the photons 2. increasing kV will increase the amount of scatter radiation directed toward the IR 3. decrease in mAs will increase in the amount of scatter radiation directed toward the IR 4. decrease kV will increase in the penetration of the photons

State the mAs maintenance formula and explain when this formula should be used (2 points each)

An area of anatomy that has low contrast is the:

If the statement is true, type “true” and “false” if it is false. Correct the False Statements. (2 point each) Angling the x-ray beam or the part will result in shape distortion.

With digital receptors, the consistent use of higher than necessary exposure indexes has what effect on patient dose?

Which of the following affect radiographic contrast?

Explain exposure indexes. (example high and low). (2 pts)

This determine the gray level that can be assigned to a pixel is the:

If the statement is true, type “true” and “false” if it is false. Correct the False Statements. (2 point each) Because overexposure of the digital image receptor typically produces an image with appropriate brightness and no quantum noise, all studies should be done with a little more exposure than needed.

Which of the following combinations would result in an image with the least amount of magnification?
