non-invasive measurement

Non-invasive measurement refers to methods of assessing data without requiring any physical intrusion into the body or system. In medical contexts, this could mean techniques like ultrasound or MRI scans, which visualize internal structures without needing surgery. In other fields, such as environmental monitoring, it can involve using sensors or cameras to collect information without disturbing the subject. The key advantage of non-invasive methods is that they minimize risk and discomfort while providing valuable insights, making them safer and often more accessible for individuals or systems being studied.
