When performing a quality control check, what is a 'tolerance range'?

A 'tolerance range' refers to the acceptable limits within which test results must fall for equipment to be considered functional. In quality control, it is crucial to establish these limits to ensure that medical imaging equipment operates correctly and produces reliable results. When test results remain within this specified tolerance range, it indicates that the equipment is functioning properly and is capable of delivering accurate diagnostic information.

This concept is particularly important in fields such as medical imaging, where any deviation outside the tolerance range might compromise patient safety or diagnostic efficacy. It allows for systematic checks that help maintain equipment performance over time, ensuring compliance with regulatory and safety standards.

Tolerance ranges are determined based on various factors, such as manufacturer specifications, industry guidelines, and clinical requirements, which further reinforces their importance in quality control procedures.
