Non-Invasive

Non-invasive refers to a medical procedure or diagnostic tool that does not require the insertion of instruments or devices into the body. In the context of space and astronautical engineering, non-invasive techniques are used to study and monitor the health of astronauts during spaceflight. These techniques include imaging technologies such as ultrasound, magnetic resonance imaging (MRI), and computed tomography (CT) scans, as well as physiological monitoring devices that can measure vital signs such as heart rate, blood pressure, and oxygen saturation levels. Non-invasive techniques are preferred in spaceflight because they are less invasive and less risky than traditional invasive procedures, which can be difficult to perform in microgravity and can pose a risk of infection or other complications. Non-invasive techniques also allow for real-time monitoring of astronaut health, which is critical for ensuring the safety and well-being of crew members during long-duration space missions.
