Which of the following is not a factor to consider in pediatric radiography?

In pediatric radiography, there are numerous factors that impact the effectiveness and safety of imaging. While the child's age and size are critical as they influence both the radiation dose and the positioning needed for accurate images, the level of parental involvement plays a significant role in ensuring the child is calm and cooperative during the procedure. The method of immobilization is also essential to secure the child in the correct position safely, minimizing movement that could result in blurry images or the need for repeat exposures.

The time of day, however, is generally not a significant consideration in the context of pediatric radiography. While it may affect scheduling, the procedures themselves, as well as the considerations for a child's engagement and safety, are more relevant to the variables that impact the quality and success of imaging. Therefore, time of day does not typically emerge as a critical factor in evaluating pediatric radiography protocols.
