| Title |
| Radiographic Imaging, Part 7: Exposure Selection ...COMING SOON! (0 credit hours) |
| Abstract |
| Exposure Selection is the seventh of nine modules in the Radiographic Imaging course.
This module will help you understand the relationships of technique factors and their effects on exposure selection. You will learn more about how factors, such as mAs and kVp, affect radiographic qualities like density and contrast so that you can make selections that will produce the best images possible |

| Objectives |
On completion of this module, you should be able to do the following:
1. Define the important terms in the module.
2. Explain the impact of kVp selection on contrast, density, patient dose, and scatter.
3. Explain how mAs selection relates to balance with kVp, density, SID, and motion blur.
4. State the inverse square law and describe how it relates to SID.
5. Describe the advantage and disadvantage of using a grid.
6. Explain why added filtration is used generally and why compensating filters are used in some circumstances.
7. Describe what is different about falling load generators. |
