How often should the screen/film contact procedure be performed?

The screen/film contact procedure is essential in radiography to ensure the quality of the images and accuracy in the results. Performing this procedure semi-annually strikes a balance between maintaining image quality and not over-frequenting the quality control processes, which could cause unnecessary disruptions or delays in radiographic work.

By conducting this procedure every six months, operators can effectively monitor any changes in screen/film contact due to factors like equipment wear and tear or environmental changes, ensuring that any issues can be addressed promptly. This interval allows for sufficient time to evaluate the overall performance of the radiographic system and make necessary adjustments, ultimately leading to improved diagnostic outcomes.

More frequent evaluations, such as monthly or weekly, while they could catch issues earlier, may not be practical and could lead to inefficiency without significant benefit, as most systems remain stable with proper initial calibration and maintenance. An annual check, although less frequent, might not provide adequate oversight and could allow subtle problems to go unnoticed longer than is ideal. Thus, semi-annually provides a best practice approach in radiographic operations.
