1
Radiographs are evaluated by a definable standard called:
Radiographic criteria
2
What are the five basic radiographis criteria?
1. Structures shown
2. Positioning
3. Collimation and CR
4. Exposure criteria
5. Image Markers
3
Describe "structures shown" in relation to radiographic criteria.
The anatomic parts and structures visualized on a radiograph.
4
Describe "positioning" in relation to radiographic criteria.
Placement of body part in relationship to IR.
Positioning factors important for projection.
5
Describe "Collimation and CR" in relation to radiographic criteria.
Describes how collimation borders should be seen.
Location of CR
Center of collimation.
6
