Thermal imaging

Definition

Thermal imaging is a technique that uses infrared radiation to create images based on the heat emitted by objects. This method captures temperature variations, allowing for the visualization of thermal patterns in various environments, including biological systems. By detecting changes in temperature, thermal imaging provides insights into metabolic processes and physiological states within living cells.
