Increasing Precision in Diagnostic Equipment
Precision is at the heart of every diagnostic device. The precision of a system is the degree to which the system will consistently provide the same result given the same operating conditions. Precision is crucial – whether a system is a complex magnetic resonance imaging (MRI) sensor, an embedded tire pressure sensor, or a low-cost blood glucose meter – because it serves as the foundation for both accuracy and reliability. For example, if a meter’s readings between two equivalent samples vary significantly, it will be difficult for the system to determine an appropriate response.
