* A radiologic technologist is using an X-ray machine with a grid to reduce scatter radiation. The initial exposure settings without a grid were 5 mAs. After placing a 8:1 grid, what should the new mAs be to maintain image receptor exposure?

* For a histogram in digital radiography, what does the vertical (Y) axis represent? 

Increasing kVp of an x-ray beam will result in the photon having:

* If an object is positioned with its long axis parallel to the image receptor (IR) but the central ray (CR) is angled, what type of shape distortion will occur?

If you had used 40 mAs at 75 kVp at a distance of 72” and then you repeat the image at a distance of 40”, what would your new mAs need to be in order to maintain your IR exposure?

The pixel size in CR/PSP imaging is determined by:
