Non-invasive diagnostics

Definition

Non-invasive diagnostics refers to medical techniques that allow for the assessment of a patient's health without the need for invasive procedures, such as surgery or needle biopsies. This approach emphasizes the use of external methods to gather critical information about a patient's condition, minimizing discomfort and risk. In the realm of terahertz biosensing and medical diagnostics, non-invasive techniques leverage terahertz radiation to analyze biological tissues and detect diseases at an early stage without compromising the integrity of the body.
