Non-invasive measurement refers to techniques that gather data without needing to penetrate or disturb the body. This approach is commonly used in medical diagnostics, allowing healthcare professionals to assess a patient's condition through methods like ultrasound, MRI, or CT scans. These techniques provide valuable information while minimizing discomfort and risk to the patient. In addition to healthcare, non-invasive measurement is also utilized in various fields such as environmental monitoring and material testing. For example, sensors can measure air quality or temperature without altering the environment. This versatility makes non-invasive methods essential for safe and effective data collection across multiple disciplines.
