Student Experiment Radiographic Unit Visual Check
To ensure that the components in an x-ray room are present and functioning according to
1. Radiographic System Visual Inspection Checklist from CD-ROM
2. Tape measure
Using a checklist, check the following items. Indicate “pass” by a check mark and “fail” by an F.
1. Source-to-image distance (SID) indicator: Check accuracy of SID using a tape measure.
Remember to measure from the focal spot.
2. Perpendicularity: Stand at the end of the table and see if the tube and collimator appear to be
perpendicular to the tabletop.
3. Angulation indicator: Use a protractor to verify the accuracy of the indicator.
4. Locks: Check the function of all locks.
5. Field light: Determine whether the field light is functioning and whether it is of sufficient
brightness using a photometer.
6. Bucky center light: Verify that the light is centered to the bucky.
7. High-tension cables: Check all cables for frayed coverings, discolored insulation, tight bends,
and unsupported areas.
8. Overhead tube crane movement: Move the crane system and make sure that it moves without
9. Bucky lock: Ensure that the lock is functioning.
10. Cassette lock: Verify that the cassette lock holds the cassette firmly.
11. Measuring caliper: Check caliper with ruler to verify accuracy.
12. Handswitch placement: Should be mounted in fixed position behind barrier.
13. Panel switches, lights, and meters: Check for proper functioning and accuracy.
14. Technique charts: Ensure that technique charts are present.
15. Overload protection: Verify the function of the technique overload system by attempting to
make an exposure at maximum kilovolt (peak) (kVp), milliampere (mA), and time factors.
1. Comment on the information gathered from the checklist. Indicate any conditions that fail and
describe how they would affect both radiation safety and radiographic quality.
2. Give any recommendations for improvement of the conditions in the radiographic room that
was evaluated with the checklist.
3. Submit the checklist with the analysis.
