Increased Sensitivity

Definition

Increased sensitivity refers to the enhanced ability of a measurement system to detect small changes or weak signals in data. This characteristic is crucial in various advanced imaging and sensing techniques, where subtle differences can indicate significant biological or physiological changes. By improving sensitivity, these technologies can provide more accurate and reliable information about the system being studied, leading to better insights into biological processes and improved diagnostic capabilities.
