Performing Chest X-Rays at Inspiration in Uncooperative Children: The Effect of Exercises with a Training Program for Radiology Technicians

Abstract EN

Objective.

It is difficult to acquire a chest X-ray of a crying infant at maximum inspiration.

A computer program was developed for technician training.

Method.

Video clips of 3 babies were used and the moment of deepest inspiration was determined in the single-frame view.

12 technicians simulated chest radiographs at normal video speed by pushing a button.

The computer program stopped the video and calculated the period of time to the optimal instant for a chest X-ray.

Demonstration software can be tested at website online.

Every technician simulated 10 chest X-rays for each of the 3 video clips.

The technicians then spent 40 minutes practicing performing chest X-rays at optimal inspiration.

The test was repeated after 5, 20, and 40 minutes of practice.

Results.

6 participants showed a significant improvement after exercises (collective 1).

Deviation from the optimal instant for taking an X-ray at inspiration decreased from 0.39 to 0.22 s after 40 min of practice.

6 technicians showed no significant improvement (collective 2).

Deviation decreased from a low starting value of 0.25 s to 0.21 s.

Conclusion.

The tested computer program improves the ability of radiology technicians to take a chest X-ray at optimal inspiration in a crying child.
