Non-invasive imaging

Definition

Non-invasive imaging refers to techniques that allow for the visualization of internal structures and processes within biological systems without the need to penetrate or disturb the subject. This method is crucial in medical diagnostics and research, as it provides valuable information about health conditions while minimizing risk and discomfort to patients. The ability to obtain high-quality images through non-invasive methods enhances the study of biological systems, particularly in understanding complex interactions at the molecular level.
