Non-invasive techniques

Non-invasive techniques are methods used in various fields, such as medicine, research, and environmental studies, to observe or gather information without physically entering or altering the body or systems being studied. For example, in medicine, techniques like ultrasound or MRI provide images of internal organs without surgery. In environmental science, satellite imagery monitors land changes without direct contact. These methods are valuable because they minimize risk and discomfort, allowing for safer evaluations and interventions.
