Radiographs of the abdomen should demonstrate structures with:1 adequate density2 long scale contrast3 high contrast

What is the effect on radiographic density when filtration is added to the collimator?

Start with no grid, change to a 16:1 ratio grid 

Radiographic density using conventional imaging is best defined as the .

A radiograph of the shoulder is obtained in the college lab using 75 kVp, 24 mAs and results in a 440 Exposure Index (EI). What mAs should be used to produce a 220 EI?

High kVp produces which of the following:

As a general rule, changing the SID from 40″ to 72″ requires which of the following to maintain radiographic density using conventional imaging with all other factorsremaining constant?

Start with 200 mA and 80 ms, change to 400 mA and 40 ms
