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

Describe "Exposure Criteria" in relation to radiographic criteria.

Describes how technique can be evautated for optimum exposure of body part.
Motion.

7

Describe "Image markers" in relation to radiographic criteria

Patient side markers (R or L)
Time markers (as needed)
