For yearly quality control, what is the acceptable error for linearity of radiating power?

The acceptable error for linearity of radiating power in the context of yearly quality control is typically defined as 10%. This standard is important because linearity refers to the consistency in the output of the radiating power across a range of exposure levels. If the linearity is out of this acceptable range, it could indicate issues with the equipment or the need for recalibration, which can affect the accuracy of diagnostic imaging or therapeutic procedures.

A linearity error beyond 10% can compromise the diagnostic quality of the imaging and influence clinical decision-making. Maintaining this strict limit is crucial for ensuring patient safety and the reliability of the results obtained from imaging equipment.
