the process or techniques used to create visual representations of the interior or exterior of an object, body, or system for analysis, diagnosis, or research. In healthcare and science, imaging is used to observe structures, detect abnormalities, monitor changes over time, and guide treatment decisions. It encompasses a wide range of methods — from simple photographs to complex radiological scans.
Example
In a rheumatology study, imaging may involve using MRI to visualize joint inflammation and cartilage damage in patients with arthritis. These images help researchers and clinicians track disease progression and evaluate the effectiveness of treatments.
