What is the acceptable error percentage for field alignment during yearly QC checks?

The acceptable error percentage for field alignment during yearly quality control (QC) checks is typically set at 2%. This standard is critical in ensuring that imaging systems are operating correctly, as precise field alignment affects the accuracy of diagnostic images and the overall performance of radiological equipment.

Maintaining a strict limit of 2% is important because even small misalignments can lead to significant errors in image interpretation, potentially impacting patient diagnosis and treatment. A tighter tolerance level assures that the equipment is functioning optimally, minimizing the risk of adverse outcomes from imaging procedures.

Furthermore, adherence to this standard is part of a comprehensive QC program that ensures compliance with national and international safety and quality standards set for medical imaging. This rigorous approach not only helps in maintaining high-quality imaging services but also promotes patient safety and confidence in radiological examinations.
